摘要
目的探讨3.OTMRI磁敏感加权成像(SWI)技术对轻型脑损伤(MBI)的早期诊断。方法对周口市中心医院神经外科收治的42例入院时头颅CT阴性的MBI患者在入院48h内行3.0TMRI—SWI序列检查,明确脑微出血灶(cMB)的部位、数量等。结果42例中CMB位于皮层18例(42.9%),脑白质14例(33.3%),胼胝体7例(16.7%),基底节及脑干3例(7.1%);CMB数量单发20例(47.6%),2个14例(33.3%),多发8例(19.1%)。结论SWI为头颅CT阴性的MBI患者提供了确切的早期诊断依据,且量化了CMB的程度和范围,结合伤后昏迷时间明确了原发性脑损伤的鉴别诊断,为MBI的临床治疗及顸后评估提供了直接的影像学基础。
Objective To investigate the early diagnosis of mild brain injury (MBI) by 3.0T MRI susceptibility weighted imaging (SWI). Methods Forty-two cases of MBI in Zhoukou central hos- pital with negative head CT were examined by 3.0T MRI-SWI in 48 hours and identified location and quantity of cerebral microbleed(CMB). Results In 42 cases, 18 cases (42.9%) with CMB located in the cortex, 14 cases (33.3%) located in alba, 7 cases(16.7% ) located in corpus eallosum, 3 eases (7.1%) located in basal nucleid and brainstem. As to the quantities of CMB, 20 cases (47.6%) were single, 14 cases (33.3%) were double, 8 cases(19. 1% ) were more than three. Conclusions SWI exactly provides early diagnosis with negative head CT and quantifies degree and range of CMB, it identi- fies the differential diagnosis of primary brain injury together with coma time postinjury. It also provides first-hand iconography for clinical therapy and evaluatin~ oro^nosis.
