<description><![CDATA[Objective: To evaluate the value of magnetic resonance angiography (MRA), three-dimensional arterial spin labeling (3D-ASL) and intravoxel incoherent motion imaging (IVIM) in transient ischemic attack (TIA). Materials and Methods: Fifty-two patients with clinically diagnosed TIA underwent multi-modal MRI scans including DWI, MRA, 3D-ASL (PLD=1.5 s) and IVIM within 24 h of symptom onset. The detection rate of hypoperfusion in patients with TIA was evaluated by different methods, and χ2 tests were performed. The paired t test was applied to compared cerebral blood flow (CBF), pure diffusion coefficient (D), pseudo-diffusion coefficient (D*) and perfusion fraction (f) measurements between hypoperfusion areas and contralateral normal brain regions. Pearson correlation was used to evaluate the correlations between rD*, rf and rCBF. Results: There was no significant difference in the detection rate of hypoperfusion between ASL and f (P＞0.05). There was no significant difference in the positive rate between the three techniques (MRA、ASL and IVIM) and MRA combined with ASL (P=0.426). No positive result was found in D. The CBF and f in the affected sides were lower than that of contralateral areas (P＜0.05), and the difference was significant (P＜0 05). The D and D* between the affected sides and contralateral areas were not statistically significant (P＞0.05). A significant correlation was detected between rf and rCBF. No statistically significant correlation was observed between rD* and rCBF. Conclusions: The results of IVIM f and 3D-ASL for the diagnosis of changes of brain perfusion of patients with TIA are consistent, which can be used for evaluating the real situation of cerebral perfusion. The combination of angiography and perfusion imaging is more helpful for early diagnosis of TIA, providing accurate imaging basis for clinic, and early treatment for reducing the occurrence of cerebral infarction.]]></description>

<description><![CDATA[Objective: In this study, we use multiple inversion time-pulsed arterial spin labeling (mTI-ASL) technique to quantitatively analyze the difference between recurrence and radiation injury of glioma after operation, to further evaluate the value of mTI-ASL technique in differential diagnosis between recurrence and radiation injury of glioma. Materials and Methods: In this study, 20 cases of glioma recurrence, 10 cases of radiation injury subjects were collected. We used Siemens 3.0 T Skyra scanner to collect, mTI-ASL sequence was performed on a 3.0 T MR scanner (Magnetom Skyra, Siemens Healthcare, Erlangen, Germany) after surgery and radiotherapy in patients with glioma. The original image of mTI-ASL was post processed on MATLAB software to obtain CBF and ATT maps. The region of interest was delineated manually by using MRI cron soft ware. Independent sample t-test was used to compare the parameters of the region of interest (ROI) related to recurrence and radiation injury of glioma after operation, and to evaluate the difference of CBF and ATT values of quantitative parameters, so as to evaluate the ability of mTI-ASL technology to differentiate the two parameters. Results: (1) CBF values of recurrence after glioma surgery (6.38±1.41) were higher than those of radiation injury (2.30±0.37). There was significant difference between them (P＜0.01). (2) ATT values of recurrence after glioma surgery (0.19±0.30) were higher than the CBF values of radiation injury (0.16±0.12), and the difference was statistically significant (P＜0.01). Conclusions: The mTI-ASL technique can distinguish the recurrence and radiation injury of glioma after operation.]]></description>

<link>http://med-sci.cn/cgzcx/en/en_articlexml.asp?doi=10.12015/issn.1674-8034.2020.05.004</link>
<description><![CDATA[Objective: To investigate the changes of functional connectivity (FC) between amygdala and whole brain regions after acute alcohol exposure in healthy young adults. Materials and Methods: Twenty-eight healthy young volunteers were recruited to evaluate the cognitive function with the Mini-mental State Examination (MMSE), MMSE score≥24. fMRI data were collected before and 0.5 h after drinking, and blood alcohol concentration (BAC) was measured at 0.5h after drinking. DPARSF software was used to preprocess the resting state data, and the bilateral amygdala was used as the seed point to correlate with the time series of all other voxels in the whole brain. (1) The paired sample t test was used to compare the difference between amygdala-whole brain FC before and after drinking. (2) The subjects after drinking were divided into high and low groups according to BAC. The independent sample t test was used to compare the FC difference between the two groups. Results: A total of twenty-three healthy volunteers (12 males and 11 females) were enrolled after screening. As compared with that before drinking, left amygdala-whole brain FC enhanced areas include bilateral occipital lobe, left middle temporal gyrus, left inferior parietal gyrus and left cerebellum, FC decreased in right superior frontal gyrus, right middle temporal gyrus, right hippocampus and parahippocampal gyrus (Puncorr＜0.001, voxels＞10). Right amygdala-whole brain FC enhanced areas include left anterior central gyrus, right cuneus, FC decreased in left cerebellum, left hippocampus and parahippocampal gyrus, right basal ganglia, left temporal fusiform gyrus (Puncorr＜0.001, voxels＞10). As compared with the low BAC group, FC of right amygdala-whole brain decreased in left insular lobe, left superior temporal gyrus, left occipital lobe, right middle frontal gyrus in the high BAC group (Puncorr＜0.001, voxels＞10). There was no significant difference region in FC of left amygdala-whole brain between high and low BAC groups. Conclusions: Acute alcohol exposure can cause FC changes between amygdala and multiple brain regions, which provides imaging evidence for some clinical manifestations after acute alcohol consumption; the right amygdala may be more susceptible to alcohol.]]></description>

<link>http://med-sci.cn/cgzcx/en/en_articlexml.asp?doi=10.12015/issn.1674-8034.2020.05.007</link>
<description><![CDATA[Objective: A digital method for eddy-current precompensation based on high resolution gradient waveform generator is proposed. Materials and Methods: Digital precompensation waveform is calculated from standard gradient waveform by field programmable gate array (FPGA). Then the original waveform and precompensation waveform are transmitted into two separated digital-to-analog converters (DAC) and transformed to analog signals respectively. Finally, compensated waveform is generated by adding the two analog waveforms. Besides, the precompensation waveform described by five various exponential decay terms is calculated timely using high-speed clock and synchronization trigger method. Results: Digital eddy-current precompensation based on two 20 bit DACs achieved higher resolution, and more precise than 23 bit resolution. Meanwhile, this method considerably reduced delay time between compensated waveform and trigger signal as well as keep it constant. Conclusions: High resolution method achieves better experimental result than analog or traditional digital eddy-current precompensation method.]]></description>

<description><![CDATA[Objective: To investigate the value of ADC, eADC and rADC in breast magnetic resonance diffusion-weighted imaging (DWI), combined with MRI plain scan for the diagnosis and differential value of suspected breast cancer. Materials and Methods: Forty-one patients underwent DWI imaging and were enrolled in the BI-RADS grade IV, and confirmed by surgery and pathology. The ADC value, eADC value and rADC value were measured in the lesion area of interest. The t test was used to compare the two groups. The difference between the good and the malignant was statistically significant at P＜0.05. At the same time, according to the size of the ADC value, the distribution of benign and malignant statistics was performed, and the surgical pathological results were used as the gold standard for statistical analysis. Results: In the pairwise comparison, the ADC and rADC values of malignant lesions were lower than those of benign lesions, and the eADC value was higher than that of benign lesions, and the difference was statistically significant (P＜0.05);The pathological diagnosis was the gold standard, and the critical value of benign and malignant breast lesions was identified by 1.440×10-3 mm2/s. The sensitivity was 85.7%, the specificity was 55.0%, and the accuracy was 70.7%. The ADC value ＜1.440×10-3 mm2/s in DWI was used as the criterion for malignancy, Kappa=0.712, which was in good agreement with pathological diagnosis. Conclusions: DWI techniques (ADC values, eADC values, and rADC values) are reliable indicators for identifying differential breast cancer by magnetic resonance imaging; combined with MRI plain scan is more important for the differential diagnosis of benign and malignant BI-RADS classification and grade Ⅳ lesions, and has guiding significance for clinical treatment.]]></description>

<description><![CDATA[Objective: To evaluate the diagnostic value of Magnetic resonance DWI-ADC values in diagnosis of sarcopenia on perimenopausal women. Materials and Methods: Women aged 21—30 and 41—60 who accepted MRI in Changˊan Hospital of Dongguan City from Mar 2017 to Nov 2019 was recruited and their data were collected. According of age the included subjects were divided into three groups, namely I group of 21—30 years old, Ⅱ group of 41—50 and Ⅲ group of 51—60. DWI images from the upper margin of the thoracic 12 vertebra to the lower margin of the lumbar 4 vertebra were captured with DWI sequences at Siemens Essenza 1.5 T system. The average ADC values of paravertebral muscles at the level of the lumbar 3 vertebra on the automatically generated ADC maps were measured. SPSS 21.0 was used to perform all analyses. The means of average ADC values were described as (x±s). Paired-sample t test was used to compare difference between the means of average ADC values of psoas and erector spinae. Single factor analysis of variance (ANOVA) was used to compare differences on the means of average ADC values of paravertebral muscles among three groups. The difference was statistically significant with P＜0.05. Results: Three hundred and sixty-one subjects were included. The means of average ADC values of psoas and erector spinae were respectively 1.279±0.133 and 1.119±0.109, and there was a significant difference between the two groups (t=25.52, P=0.000). The means of average ADC values of paravertebral muscles from I group (n=105), Ⅱ group (n=143) and Ⅲ group (n=113) were respectively 1.220±0.091,1.208±0.084 and 1.159±0.122, and there were significant differences among the three groups (F=11.46, P=0.000). Through further pairwise comparison significant differences were found between I group and Ⅱ group (P＜0.01), Ⅱ group and Ⅲ group (P＜0.01). Based on 1.038 (x-2SD) of average ADC values of paravertebral muscles from I group as diagnostic thresholds of sarcopenia, a total of 23 from Ⅱ group and Ⅲ group were below 1.038. Twenty-two cases among them were confirmed sarcopenia by follow-up. Conclusions: The method of quantifiable DWI-ADC values can reduce the error caused by individual differences in diagnosing sarcopenia and is of great value for qualitative diagnosis of sarcopenia.]]></description>

<description><![CDATA[The ovarian tumor is one of the most common gynecologic tumors with various pathological types and high incidence. Traditional imaging diagnosis is often based on qualitative analysis of medical images and thus lack of objectivity. In recent years, with the development of artificial intelligence, radiomics is an emerging method for the research of tumor diseases. This method could extract a large number of quantitative features from magnetic resonance imaging, computed tomography and ultrasound medical images, and analyze these features to distinguish between benign and malignant ovarian tumors, to identify the type and stage of ovarian cancer and to forecast the prognosis of ovarian tumors. Therefore, radiomics might provide new clues for further understanding the biological characteristics of ovarian tumors.

<description><![CDATA[With the rapid development of magnetic resonance imaging technologies and big data era, the diagnosis of tumors does not only depend on imaging manifestations. How to quantitatively evaluate the characteristics of tumors has gradually become a hot research issue. T1-weighted imaging (T1WI), T2-weighted imaging (T2WI), diffusion weighted imaging (DWI) and dynamic contrast enhancement (DCE) techniques have become routine sequences during the daily MRI scanning at present. The signal intensity on the weighted images cannot directly reflect the characteristics of the tissue. As one of the MR quantitative technologies, T2 mapping is objective, reproductive and stable, and has been frequently applied to the researches about osteoarthritis and myocardial edema. With the development of MR imaging, it has been applied to the studies of body tumor gradually in recent years. This article reviews the progress about quantitative research of T2 mapping in body tumors.]]></description>
