【摘要】：目的:探討磁敏感加權(quán)成像技術(shù)(SWI)對腦梗死合并腦微出血的診斷能力及微出血的臨床應(yīng)用價(jià)值。方法:分析2015年1月到2016年12月我院收治的腦梗死患者87例完整的臨床資料,并行常規(guī)磁共振成像及SWI序列檢查,并根據(jù)是否發(fā)生微出血(CMBs)分為以下兩組:CMBs組(A組48例),非CMBs組(B組39例)。統(tǒng)計(jì)分析患者CMBs病灶數(shù)目、病灶分布范圍,觀察比較兩組患者的有關(guān)危險(xiǎn)因素。根據(jù)是否出現(xiàn)出血性轉(zhuǎn)化(HT)分為HT組(C組15例)和非HT組(D組72例),觀察比較分析兩組的危險(xiǎn)因素。結(jié)果:在腦微出血患者中,SWI序列檢出微出血病灶947個(gè),檢出率可達(dá)100%;MRI T1WI序列檢出微出血病灶134個(gè),檢出率為14.1%;MRI T2WI序列檢出微出血病灶152個(gè),檢出率為16.1%;FLAIR序列檢出微出血病灶159個(gè),檢出率為16.8%;SWI與其余3種方法相比,對腦微出血病灶檢出率具有優(yōu)勢,且差異具有統(tǒng)計(jì)學(xué)意義(P0.05)。A、B兩組患者在高血壓級別、收縮壓、舒張壓、腔梗級別、腦白質(zhì)變性級別方面進(jìn)行比較,差異均具有統(tǒng)計(jì)學(xué)意義。C、D兩組在微出血、腦梗死面積方面差異具有統(tǒng)計(jì)學(xué)意義(P0.05)。結(jié)論:SWI能敏感的檢測CMBs病灶,CMBs可能增加HT的風(fēng)險(xiǎn),對于腦梗死患者治療、轉(zhuǎn)歸及預(yù)后等方面具有重要的臨床應(yīng)用價(jià)值。
[Abstract]:Objective: to evaluate the value of magnetic sensitivity weighted imaging (SWI) in the diagnosis of cerebral infarction complicated with microhemorrhage. Methods: 87 patients with cerebral infarction admitted to our hospital from January 2015 to December 2016 were analyzed. Routine magnetic resonance imaging and SWI sequence were performed. According to the occurrence of microhemorrhage, (CMBs) was divided into two groups: group A (n = 48) and group B (n = 39). The number and distribution of CMBs lesions were statistically analyzed and the relative risk factors were observed and compared between the two groups. According to whether hemorrhagic transformation occurred, (HT) was divided into HT group (group C, n = 15) and non-HT group (group D, n = 72). The risk factors of these two groups were compared and analyzed. Results: in the patients with intracerebral microhemorrhage, 947 microhaemorrhage lesions were detected by T1WI sequence, and the detectable rate was up to 134 by T1WI sequence, and the detectable rate was 14.1MRI T2WI sequence to detect 152 microhemorrhage lesions. The detection rate was 16.1% flair sequence to detect 159 microhemorrhage lesions. The detection rate of SWI was 16.8%. Compared with the other three methods, SWI had an advantage over the other three methods, and the difference was statistically significant (P0.05). The systolic blood pressure (SBP), diastolic blood pressure (DBP) in the two groups were significantly higher than those in the other three groups. Compared with the grade of cerebral infarction and white matter degeneration, the difference was statistically significant. The difference between the two groups in the area of microhemorrhage and cerebral infarction was statistically significant (P0.05). Conclusion the detection of CMBs foci in CMBs may increase the risk of HT, and has important clinical value in the treatment, outcome and prognosis of patients with cerebral infarction.
