| ［摘要］ 目的 探讨磁共振成像（MRI）在颅脑损伤中的诊断作用。方法 对48例急性脑损伤患者，用自身对比的方法进行计算机X线体层扫描（CT）与MRI检查；分析两者的优缺点。结果 硬膜下血肿、硬膜外血肿的诊断, CT与MRI结果相符；蛛网膜下腔出血、颅骨骨折的诊断，CT较敏感；脑叶挫裂伤、脑深部挫裂伤的诊断, MRI明显优于CT。结论 MRI能明显提高脑叶挫裂伤和脑深部挫裂伤诊断敏感性, 减少漏诊和误诊。 |

| Abstract: |
| ［Abstract］ Objective To study the diagnostic value of MRI in patients with craniocerebral trauma.Methods The 48 cases of cerebral trauma were examined with CT and MRI simultaneously using self-comparative method, and the advantages and disadvantages of both examination were analyzed.Results In the light of subdural hematoma and epidural hematoma, both MRI and CT had the similar diagnostic significance, but considering traumatic subarachnoid hemorrhage and skull fracture, CT was more sensitive than MRI.However, MRI was more reliable than CT in diagnosing cortical cerebral contusion and laceration, and deep cerebral contusion and laceration. Conclusion MRI can increase diagnostic sensitivity in recognizing cortical cerebral contusion and laceration, and deep cerebral contusion and laceration. |
