Abstract Objective To study the clinical application value of susceptibility weighted imaging (SWI) for reperfusion hemorrhage in patients with hemorrhagic cerebral infarction and perform imaging analysis on the results. Methods From January 2016 to March 2021, a total of 70 patients with hemorrhagic cerebral infarction who were treated in the Department of Radiology, Jiangmen People′s Hospital were selected as the research objects. All patients were examined with a 1.5T superconducting MR imager, followed by regular MRI scans and magnetic sensitivity weighted imaging examinations. With digital subtraction angiography (DSA) as the diagnostic gold standard, the diagnostic efficiency and bleeding volume of different MRI technologies were compared, and the imaging characteristics of the two technologies were analyzed. Results There was no statistically significant difference in sensitivity between susceptibility weighted imaging and conventional MRI scans (P>0.05). The accuracy of susceptibility weighted imaging for hemorrhage, cerebral infarction, reperfusion, hemorrhage and specificity was higher than that of the accuracy of conventional MRI scans and the difference was statistically significant (P<0.05). The bleeding volume of magnetically weighted imaging was greater than that of conventional MRI scans the mean volume was, and the difference was statistically significant (P<0.05). Conclusion Susceptibility weighted imaging examination has high accuracy and specificity for reperfusion bleeding in patients with hemorrhagic cerebral infarction. It can scan the range of intracerebral hemorrhage as completely as possible, and provide more reliable diagnostic results for clinical treatment. It is clinically worthy of promotion.
