目的:介绍MRI及CT在脑血管疾病诊断中的特点。方法 :对36例脑血管疾病患者在治疗前及治疗2～4个月后复查MRI及CT。结果 :36例患者中脑血肿18例和脑梗塞12例均获得满意的诊断。6例蛛网膜下腔出血患者在MRI与CT检查比较 ,CT扫描优于MRI检查。MRI对脑血肿亚急性期和脑梗塞早期诊断明确。对蛛网膜下腔出血7d之内的病灶 ,在MRIT1和T2加权像中信号显示不敏感 ,而在CT扫描显示颅内纵裂内为高密度条状影[1]。36例均做治疗后复查。脑内病灶CT和MRI显示正常或接近正常。结论 :MRI对脑血肿、脑梗塞病灶有肯定的诊断。对蛛网膜下腔(7d之内)出血病灶的诊断CT优于MRI。
Objective: To introduce the features of MRI and CT in the diagnosis of cerebrovascular disease. Methods: Thirty-six patients with cerebrovascular disease underwent MRI and CT before and 2 to 4 months after treatment. Results: 36 patients with cerebral hematoma in 18 cases and cerebral infarction in 12 cases were satisfactory diagnosis. 6 cases of patients with subarachnoid hemorrhage in MRI and CT examination, CT scan is better than MRI. MRI early diagnosis of cerebral hematoma subacute and cerebral infarction clear. For lesions within 7 days of subarachnoid hemorrhage, the signals were not sensitive in the MRIT1 and T2 weighted images, whereas high-density intracranial longitudinal rupture was seen on CT scans [1]. 36 cases were done after treatment review. Brain lesions CT and MRI showed normal or near normal. Conclusion: MRI has positive diagnosis of cerebral hematoma and cerebral infarction. The diagnosis of hemorrhagic lesions in the subarachnoid space (within 7 days) is superior to MRI.
