Abstract

Objective To investigate the clinical diagnostic value of susceptibility weighted imaging (SWI) in hemorrhagic cerebral infarction. Methods 96 patients with hemorrhagic cerebral infarction of December 2010 to December 2014 in our hospital were examined by 3.0T magnetic resonance imaging (MRI). Conventional MRI, diffusion weighted imaging (DWI) and SWI were performed simultaneously. According to the result of image analysis to compare the positive detection rate of hemorrhagic cerebral infarction and hemorrhage stove with different scanning sequence. Measuring bleeding focal area, scoring method is used to evaluate different scanning sequence differences on the bleeding area. Results The positive detection rate of hemorrhagic cerebral infarction of SWI was significantly higher than T1WI, T2WI, DWI, they have significant difference (P<0.05). The positive detection rate of hemorrhage stove of SWI was obviously higher than T1WI, T2WI, DWI, they have significant difference (P<0.05). The positive detection rate of hemorrhagic cerebral infarction bleeding score total value of SWI was obviously higher than the total value T1WI combined with T2WI, DWI, they have significant difference (P<0.05). Conclusion Compared with the conventional MRI and DWI used to detect hemorrhagic cerebral infarction, SWI has higher positive detection rate, can early detect the focal cerebral infarction in bleeding, it can be used as a routine examination for diagnosis of hemorrhagic cerebral infarction.
