CT薄层重建与弥散加权成像技术在急性腔隙性脑梗死诊断中的对比研究
|
摘要
目的对比CT薄层重建与弥散加权成像(DWI)技术在急性腔隙性脑梗死诊断中的价值。方法将河源市人民医院30例急性腔隙性脑梗死患者先后进行CT薄层重建诊断和DWI技术诊断,根据确诊结果比较两种方法的病灶位置准确度及检测出直径小于5 mm的病灶概率。结果 DWI技术检测病灶位置准确度比CT薄层重建高,差异无统计学意义(P>0.05);DWI技术检测出直径小于5 mm的病灶概率高于CT薄层重建,差异有统计学意义(P<0.05)。结论相比于CT薄层重建,DWI技术在急性腔隙性脑梗死诊断中的价值更高。
Objective To compare the diagnostic value of thin-slice CT reconstruction and DWI technique in acute lacunar infarction. Methods 30 patients with acute lacunar cerebral infarction in the hospital were diagnosed by CT thin layer reconstruction and DWI technique respectively. According to the results of diagnosis,the accuracy of lesion location and the probability of detecting lesions with diameter less than 5 mm were compared. Results The accuracy of DWI in detecting lesion location was higher than that of CT thin layer reconstruction,and the difference was not significant(P>0.05). The probability of detecting lesions with diameter less than 5 mm by DWI technique was higher than that by CT thin layer reconstruction,and the difference was significant(P<0.05). Conclusion Compared with CT thin-slice reconstruction,DWI technique is more valuable in the diagnosis of acute lacunar infarction.
