PDFAbstract
Objective To evaluate the value of periodically rotated overlapping parallel lines enhanced reconstruction dwi technique for artifact reduction in MRI. Methods The 81patients of clinical suspicion of cerebral infarction from 2013 to 2015 with denture underwent MRI examination.To take the PROPELLERdwi and FSE dwi respectively. Results PROPELLER DWI in the detection of cerebral infarction lesion in 78 cases, frontal lobe, temporal lobe artifacts, respectively 1 cases, 2 cases; FSE DWI was detected in 20 patients with cerebral infarction, frontal lobe, temporal lobe, cerebellum and brainstem artifacts were 19 cases, 39 cases, 1 cases, 2 cases. Conclusion PROPELLER DWI for detection of cerebral infarction lesions have a good advantage, at the same time for the case with denture is effective, can eliminate the magnetic susceptibility artifacts, has a very active role in improving the image quality.
