<description><![CDATA[Magnetic resonance functional imaging generally refers to functional magnetic resonance imaging (fMRI) based on blood oxygen level dependence (BOLD), which responds to changes in deoxyhemoglobin concentration consequent to task-induced or spontaneous modulation of neural metabolism. Since its inception in 1990, fMRI as a non-invasive tool with good spatial resolution, has been used in a large number of studies in the cognitive neurosciences, clinical psychiatry/psychology, and presurgical planning; and fMRI is increasingly being used as a biomarker for disease, and to monitor therapy or for studying pharmacological efficacy. Recently, pattern classification and other statistical methods have been applied to data analysis of functional imaging, real-time feedback has developed rapidly, and fMRI will be more involved in clinical medicine. This paper reviews the methods, the application and the future of fMRI.]]></description>

<description><![CDATA[Cardiac magnetic resonance (CMR) is a non-invasive imaging technology, gradually playing an irreplaceable role in the diagnosis and treatment of cardiovascular diseases. This review demonstrates the progress and research highlights of Chinese CMR research in the past 30 years. From the end of the 1980s to the end of the 1990s, the domestic researchers, under the guidance of Prof. Liu Yuqing and other seniors, carried out arduous explorations based on foreign equipment. They focused on the evaluation of cardiac anatomy and ventricular function in CMR. At the turn of the century, China's CMR had reached to the development period (2000-2010). Some young talents had received professional training abroad and made a fine figure after returning to China. Through their efforts, China's cardiovascular industry had a quick leap. In the meantime, with the perfection and improvement of magnetic resonance imaging equipment and technology, especially the histological characterization represented by gadolinium contrast enhancement, it was realized that CMR was not only the gold standard for assessing the structure and function of cardiovascular diseases, but it played an important role in the prognosis evaluation of the diseases. Since 2010, China's CMR has entered a period of comprehensive prosperity, and begun to be in line with international standards. It has truly achieved the “one-stop” examination in CMR, which completed a comprehensive measurement of the morphology, function, histology, perfusion, blood flow, qualitative and quantitative analysis of microstructures and the like. Along with the rise of domestically produced equipment, unique in some respects, it is now urgent to promote and popularize CMR in China.]]></description>

<title><![CDATA[Quantitative evaluation of the cortical development on neonates based on segmentation of 3D T1WI images using transfer learning]]></title>
<link>http://med-sci.cn/cgzcx/en/en_articlexml.asp?doi=10.12015/issn.1674-8034.2019.10.004</link>
<description><![CDATA[Objective: To implement a machine learning-based segmentation method on neonatal T1WI images and assess the cortical structural maturation of preterm and term neonates. Materials and Methods: This work enrolled 50 subjects without any abnormalities on magnetic resonance imaging from the First Affiliated Hospital of Xi'an Jiaotong University, including preterm neonates, preterm newborns at the term equivalent age, and term neonates. The preliminary training of a densely convolution network was performed by using the similar neonatal dataset from the shared database. Segmentation of the local dataset was performed by using this preliminary model. The segmentation results were modified manually by experts. Then the segmentation model was trained again by using the local data from randomly selected 25 subjects. According to the segmentation quality of the validation dataset (sample size: 10), the model parameters were adjusted. Finally, this segmentation model was assessed by using Dice ratios on the testing dataset (sample size: 15). The surface area, cortical thickness, and cortical volume of left and right hemispheres of the brain were extracted based on the cortical reconstruction. Correlations between these metrics and the postmenstrual age were performed by using the Spearman partial correlation. Inter-group differences were evaluated by using the Mann-Whitney U test. Results: The proposed model could effectively segment the gray matter, white matter, and cerebrospinal fluid regions in T1WI images on neonatal brains. This method was feasible on preterm neonates, preterm newborns at the term equivalent age, and term neonates. The dice ratios ranged from 0.93 to 0.99. Significant positive correlations between surface area, cortical volume and the postmenstrual age were observed on both hemispheres (P＜0.05). Postmenstrual age-related change patterns of the cortical thickness on left and right hemispheres were different. Except that no significant inter-group difference could be found in cortical thickness, preterm neonates held smaller surface area and cortical volume on both hemispheres than term neonates (P＜0.001). Conclusions: It is feasible to implement segmentation of T1WI images on neonatal brains based on a densely connected convolution network. Metrics extracted from the image segmentation and cortical reconstruction could be used to quantitatively assess the cortical structural maturation of neonates. Cortical maturation was delayed in preterm neonates than term neonates on both hemispheres.]]></description>

<link>http://med-sci.cn/cgzcx/en/en_articlexml.asp?doi=10.12015/issn.1674-8034.2019.10.005</link>
<description><![CDATA[Objective: To investigate the relationship between vertebral-basal artery atherosclerotic vascular remodeling pattern, plaque burden, distribution characteristics and cerebral infarction by high resolution magnetic resonance vessel wall imaging (HRMR-VWI). Materials and Methods: Thirty-two patients with post-circulation acute cerebral infarction were enrolled, and routine magnetic resonance imaging (including DWI sequence) and HRMR-VWI were performed to confirm the presence of cerebral infarction in the posterior circulation blood supply area and to measure the vessel wall of the responsible vessel and calculate the remodeling index (RI) of the vessel area at the narrowest point/vascular area at the reference. Compare the area of negative and positive remolding vascular plaque area, plaque burden, and observe the location distribution and enhancement characteristics of responsible plaque. Results: HRMR-VWI found 30 patients with vertebral-basal atherosclerotic plaque, including 18 cases of basilar atherosclerotic plaque, 12 cases of vertebral artery (intracranial part) atherosclerotic plaque, and 2 cases of parabrachial infarction without obvious plaques. Responsible vascular remodeling was performed in 21 patients, negative remodeling in 7 patients, and no remodeling in 2 patients. The plaque area (6.32±3.19) mm2 and plaque load (0.51±0.13)% of the positive remodeling group were larger than the plaque area of the negative remodeling group (2.14± 1.43) mm2 and the load (0.28±0.19)%. Vertebral-basal atherosclerotic plaques often occur around the opening of the branch of the perforating artery and are more common in the dorsolateral side. Conclusions: HRMR-VWI can be used as an important examination method for the diagnosis of post-circulation acute cerebral infarction.]]></description>

<link>http://med-sci.cn/cgzcx/en/en_articlexml.asp?doi=10.12015/issn.1674-8034.2019.10.006</link>
<description><![CDATA[Objective: To investigate the fractional anisotropy (FA) in various brain regions of newborns and explore the value of diffusion tensor imaging (DTI) application in the cerebral white matter myelin development. Materials and Methods: 39 term neonates (gestational age in 37—42 weeks) and 61 premature infants (corrected to 40 weeks gestational age) were investigated by routine MRI and DTI. Their perinatal medical records and nervous system examinations showed no abnormalities. FA values were detected in the regions of interest. The differences of FA values between full term and preterm neonates were explored. Results: ①FA values in the same regions of interest (ROI) had no statistic difference between left and right hemisphere (P＞0.05). ②The FA values between preterm infants and full term infants in same white matter regions were different. FA values in ALIC, CCS, external capsule (EC) were statistically higher than in PLIC, centrum semiovale (CS), and middle cerebellar peduncles (MCP)(P＜0.05). The FA values of FPVZ were the lowest in all ROIs; and CCS and PLIC were highest. The comparison of between FPVZ and CCS, FPVZ and PLIC had significant difference respectively (P＜0.05). ③The FA values of premature and full term infants in various white matter regions were different and all values were compared in pairs. We found the values in posterior limb of internal capsule (PLIC) were higher than in anterior limb of internal capsule (ALIC), the values in occipital periventricular zone (OPVZ) were higher than in frontal periventricular zone (FPVZ), and corpus callosum splenium (CCS) were higher than corpus callosum genu (CCG). All the differences were statistically significant (P＜0.05). Conclusions: FA values can be used to evaluate the myelination quantitatively. The different FA values in preterm and full term infants suggest late myelination in preterm infants. FA values reflects the difference of the myelination time.]]></description>

<description><![CDATA[Objective: To assess the diagnosis value of proton density weighted-spectral attenuated inversion recovery (PDW-SPAIR)  in detecting active inflammations in patients with rheumatoid arthritis (RA). Materials and Methods: Retrospective analysis of 35 RA patients with active lesions confirmed clinically were elected and MR examinations of PDW-SPAIR and contrast enhancement-T1 weighted image-spectral presaturation inversion recovery (CE-T1WI-SPIR) were performed on 1.5 T MR scanner. The lesions were evaluated by two radiodiagnostic doctors, and five imaging signs (bone marrow edema, synovitis, tendonitis, soft tissue swelling, and joint effusion) were evaluated by double-blind method. Comparing the lesions of the two examination sequences showed a coincidence rate. Results: Active lesions of RA showed well in PDW-SPAIR. There was no statistical significance between the two sequences of detecting the active lesions of bone marrow edema (BME), synovitis, tendinitis, soft tissue swelling (P=0.500, 0.219, 0.625, 0.625). The detection rate of joint effusion in PDW-SPAIR was higher than CE-T1WI-SPIR (P=0.004). The coincident rate of the first four signs was between 81.8%—92.6% by two radiographers with double-blind method. Conclusions: Both PDW-SPAIR and CE-T1WI-SPIR sequences can be used to evaluate active joints of RA. PDW-SPAIR can be recommended to evaluate RA joint activity lesions in MRI without contrast-enhanced scan in RA patients.]]></description>

<description><![CDATA[Objective: To investigate the value of visual imaging in ischemic stroke using multiple b-value diffusion weighted magnetic resonance imaging (MR-DWI), that is aquaporins (AQPs) magnetic resonance molecular imaging. Materials and Methods: A total of 25 Sprague-Dawley rats were underwent transient cerebral ischemic for one hour by middle cerebral artery occlusion (MCAO). Then, the rats were quinquesected randomly into 5 groups: 1, 3, 6, 24, 48 h. Magnetic resonance imaging were performed for all of the 5 groups, containing T2-FLAIR, DWI and AQP-MRI (18b value DWI) scanning series. Relative areas of the lesions were measured for all of the imagings. The areas of AQP-MRI/T2-FLAIR mismatch were compared with that of DWI/T2-FLAIR mismatch. The correlations between MR imagings and TTC staining were analyzed. Results: The location and the range of the lesions, and severity of infarctions were clearly displayed by AQP-MRI. AQP-MRI/T2-FLAIR mismatch showed ischemic penumbra within 24 hours. The result showed that the area of AQP-MRI/T2-FLAIR mismatch was larger than that of DWI/T2-FLAIR mismatch within 24 hours, there was significant difference between them (P＜0.01). The aquaporin-apparent diffusivity coefficient (AQP-ADC) values of peripheral to the penumbra in the ipsilateral areas were much higher than that of in the contralateral areas (P＜0.05). The microscopic differences between the basal ganglia and ipsilateral distal cortex could be displayed visually in AQP-MR pseudo-color images (P＜0.01). There were no significant differences between TTC staining and AQP-MRI, DWI, T2-FLAIR results (P＞0.05), and there were significant correlations between them (r=0.903, P=0.004; r=0.935, P=0.02; r=0.872, P=0.054). Conclusions: As a new molecular imaging technology, AQP-MRI dynamic visualized ischemic stroke with multi-layer, multi-angle and more accurately. AQP-MRI had a wide range of potential applications in the diagnosis of ischemic stroke.]]></description>

<description><![CDATA[Objective: To analyze the relationship between multimode function magnetic resonance imaging (MRI) of Wistar rat epilepsy model and histopathology by comparative study. Materials and Methods: Wistar rats were divided into normal control group (n=30) and epilepsy model group (n=30). Epileptic model group established epilepsy model. Three males and three females were taken at 3 days, 1 week, 3 weeks, 5 weeks, and 8 weeks after the disease, and routine MRI, diffusion kurtosis imaging (DKI) and three-dimensional magnetization preparatory gradient echo (3D-MPRAGE) were performed. Multi-sequence brain scans, selecting bilateral symmetric regions of interest (ROI) in the gray matter (GM) and white matter (WM) regions, detecting anisotropy fraction (FA), mean diffusion coefficient (MD), and average diffusion kurtosis (MK). After the end of scan, the rat brain tissues were taken out to conduct pathological HE staining analysis. Rat brain tissue was taken for HE staining analysis to analyze the relationship between MRI parameters and pathological findings in rats. Results: With the extension of attack time, FA and MD in GM and WM areas of epilepsy model group were gradually decreased, while MK was gradually increased (P＜0.05). At the same attack time points, FA and MD in GM and WM areas of epilepsy model group were lower than those of normal control group, while MK was higher than that in normal control group (P＜0.05). The pathogenic time of rats in the epilepsy model group was negatively correlated with FA and MD in the brain, and positively correlated with MK (P＜0.05). With the extension of attack time, the number of residual normal neurons in brain tissues of epilepsy model group were gradually decreased. At the same attack time points, number of residual normal neurons in epilepsy model group was lower than that in normal control group (P＜0.05). At different time points after attack, number of residual normal neurons in epilepsy model group was positively correlated with FA and MD, while negatively correlated with MK (P＜0.05). Conclusions: The test results of multimode function MRI in epilepsy model rats are significantly correlated with test results of brain histopathology. Msultimode function MRI can be applied as one of imaging methods for clinical diagnosis of epilepsy and assessment of disease severity.]]></description>

<description><![CDATA[Objective: To explore the significance of diffusion kurtosis imaging (DKI) technique in the study of gray matter development, this work investigated the differences of diffusion tensor metrics and kurtosis metrics in detecting the microstructural developmental changes from neonates to adults on the cerebral gray matter nuclei. Materials and Methods: Twenty-two term neonates (postmenstrual age of 39—44 weeks) and 22 adults (age of 18—26 years) were included. DKI was performed in a 3.0 T scanner with the following variables: b values=0, 500, 1000, 2000 and 2500 s/mm2; 18 gradient directions per nonzero b value. Fractional anisotropy (FA), mean diffusivity (MD), axial diffusivity (AD), radial diffusivity (RD), mean kurtosis (MK), axial kurtosis (AK) and radial kurtosis (RK) were calculated by using the DKI model. Four regions of interest (ROIs) of the cerebral gray matter nuclei, including thalamus, putamen, globus pallidus and caudate nucleus, were selected based on the brain atlas. Results: Compared with neonates, FA, MK, AK and RK increased in the four adults gray matter nuclei, while MD, AD and RD reduced. Except AD in thalamus (P=0.944), the mean values of FA, MD, AD, RD, MK, AK and RK in four GM nuclei were statistically different between neonates and adults (P＜0.05). The relative change ratios of MK, AK and RK ranged from 82.86% to 210.81%, while those of FA, MD, AD and RD ranged just from 1.45% to 70.59%. Conclusions: The change rates of kurtosis metrics on the gray matter nuclei between neonates and adults were higher than those of diffusion tensor metrics, which suggested that the sensitivity of kurtosis metrics was higher on the detection of microstructural changes on the gray matter nuclei. DKI has the potential to explore the developmental change of gray matter.]]></description>

<description><![CDATA[Magnetic resonance imaging (MRI) is sensitive to detect hypoxic-ischemic encephalopathy (HIE). Conventional magnetic resonance imaging technology can accurately describe the vasogenic edema in the injured area of HIE, presenting as low signal on T1WI and high signal on T2WI. However, in the early stage of brain injury, there was no significant change in TIWI and T2WI for the cytopathic edema with only slight increase in brain tissue moisture. Compared with conventional MRI, magnetic resonance diffusion imaging based on the diffusion of water molecules can better reflect the microstructure of human tissue and the movement of water molecules inside and outside the cell, and it is easier to detect early HIE. The prospect of diffusion weighted imaging (DWI), diffusion tensor imaging (DTI) and diffusion kurtosis imaging (DKI) in the diagnosis of HIE is worth exploring.]]></description>
