【摘要】：目的:探讨磁敏感加权序列成像在检测急性脑梗塞微出血中的临床应用价值。方法:选取45例急性脑梗死合并脑微出血(cerebral micro-bleeding,CMBs)患者,行常规CT、MRI及磁敏感加权成像(SWI)扫描,对CMBs的表现进行分型,并对比各个序列对CMBs的检出率。结果:45例患者共检出CMBs 238个,A型163个,B型75个。A型多分布于基底节区及侧脑室旁,呈点状/圆形或卵圆形,边界清楚。B型发生于梗死病灶内,呈不规则小条片样低信号。将SWI序列对CMBs的检出率与各个常规MR扫描序列(T1WI、T2WI、FLAIR、DWI)对CMBs的检出率进行统计学比较,差异具有统计学意义(P0.001)。结论 :SWI序列是显示急性梗死灶中CMBs的敏感检查手段。针对CMBs病灶的不同分型对脑梗死微出血的治疗和预后有重要意义。
[Abstract]:Objective: to evaluate the clinical value of magnetic sensitivity weighted sequence imaging in detecting microhemorrhage of acute cerebral infarction. Methods: 45 patients with acute cerebral infarction complicated with cerebral micro-hemorrhage were examined by conventional CT MRI and magnetic sensitivity weighted imaging (MRI). The CMBs findings were classified and the detection rate of CMBs was compared with each sequence. Results A total of 238 types of CMBs were found in 45 patients, including 163 type A and B type A, which were distributed in basal ganglia region and lateral ventricle, and were punctate / round or oval. The boundary of type B occurred in the infarcted lesion, and the signal intensity was irregular strip like low signal. The detection rate of CMBs by SWI sequence was compared with that of CMBs by T1WII T2WIFLAIRDI. The difference was statistically significant (P 0.001). ConclusionSWI sequence is a sensitive method to display CMBs in acute infarction. Different types of CMBs lesions are of great significance for the treatment and prognosis of cerebral infarction microhemorrhage.
