研究与分析脑出血中应用磁敏感加权成像诊断效果

Research and Analysis of Cerebral Hemorrhage in Application of Magnetic Susceptibility Weighted Imaging Diagnostic Results

目的探讨与分析脑出血中应用磁敏感加权成像诊断效果。方法选取本院经病理证实为脑出血的78例患者进行研究,其中单纯性脑出血者为39例,脑肿瘤出血者为39例。对患者分别采用T1WI和T2WI及MR、CE-MR、SWI序列进行检查。同时统计与分析SWI对单纯性脑出血与脑肿瘤出血的鉴别诊断情况。结果经诊断发现,(1)脑肿瘤出血者中,6例出血完全覆盖肿瘤实质者并未见明显强化,33例可见不同程度强化。采用SWI扫描,其中33例患者病变周围或局部出现粗细不等和迂曲低信号血管影像,6例患者未见血管低信号。(2)单纯性脑出血者中,13例未见明显强化,26例边缘可见轻度强化。采用SWI扫描提示39例患者未见明显肿瘤血管低信号。结论采用SWI扫描联合增强扫描及常规MR扫描可有效提高临床单纯性脑出血与脑肿瘤出血的临床诊断及鉴别率。

Objective Susceptibility Weighted Imaging Diagnostic Discussion and Analysis of the effect of the application of cerebral hemorrhage. Methods Select the hospital confirmed by pathology study of 78 patients with cerebral hemorrhage, which were simple for 39 cases of cerebral hemorrhage, brain tumor hemorrhage of 39 cases. Patients were used T1WI and T2WI and MR, CE-MR, SWI sequence to be checked. While the differential diagnosis of Statistics and Analysis of simple SWI cerebral hemorrhage and brain tumor hemorrhage. Results After diagnosis found that （1） brain tumor hemorrhage, and six cases of bleeding tumor parenchyma were completely covered and no significant enhancement seen 33 cases of varying degrees of enhancement. Using SWI scan, 33 patients with lesions appear around or partial thickness ranging from low signal and tortuous vascular imaging, six cases of patients with no vascular low signal. （2） simple cerebral hemorrhage in 13 cases no obvious enhancement, 26 cases of mild visible edge enhancement. Using SWI scan showed that 39 patients had no obvious tumor vasculature low signal. Conclusion SWI scan using joint enhanced scan and conventional MR imaging can effectively improve the clinical Simple cerebral hemorrhage and clinical diagnosis and differential rates of brain tumor hemorrhage.
