Utilization of low-field MR scanner on cerebral diseases

[Abstract] Central nervous system examination takes the majority of MR scan in clinical practice. A statistic data by Neusoft from 148 second-rank hospitals which equipped with low-field MR scanners showed that brain MR examination occupied 33.0% of the total studies. Although it is expected that the low-field MR scanner could fulfill the requirement of brain examination in most cases, there are still some problems remained due to the major drawback of low signal-to-noise ratio of low-field MR imaging. Recent improvements in low-field MR scanners have generated a renewed interest in low-field MR imaging with higher image quality and shorter scan times. In this article, we reviewed brain imaging in low-field MR, focusing on the imaging feature of intracranial hemorrhage, application of pulse sequences and the usage of contrast medium.
