摘要
目的探讨3.0T MR对高血压患者脑微出血(CMBs)诊断的临床价值。方法对77例研究对象进行3.0TMR多序列成像,并将其影像表现结合临床资料进行分析。结果 40例患者CMBs病灶表现为信号丢失,总数共计248个,SWI序列与DWI序列的检出率差异有统计学意义(χ2=26.061,P<0.05)。DWI序列分别与常规T2WI、T1WI序列检出率的差异有统计学意义(χ2=6.146,P=0.013;χ2=17.802,P=0.000)。T2WI与T1WI序列的检出率差异无统计学意义(χ2=2.689,P=0.101)。结论 3.0T MR SWI联合常规MR序列扫描技术明显提高了CMBs的检出率。
Objective To explore the clinic value of susceptibility weighted imaging （SWI） in patients with cerebral microbleeds （CMBs）.Methods 3.0T MR multiple sequences imaging was used to examine 77 patents in this study. The imaging founding and related clinical data were analyzed.Results The CMBs lesions of 40 patients showed signal loss. The total CMBs number was 248. The difference of the detection rate between SWI and DWI was significant （χ2=26.061, P〈0.05）. The detection rates differences between DWI sequence and conventional T2WI, T1WI sequence were significant （χ2=6.146, P=0.013; χ2=17.802, P=0.000）. The detection rate of T2WI and T1WI sequence was not statistically significant （χ2=2.689, P=0.101）.Conclusions 3.0T MR SWI scanning technology combined with conventional MR sequences CMBs significantly improved the detection rate.
