| 目的 通过分析比较自旋回波(SE) 序列和梯度回波T2WI (准T2 序列T2 ) 序列对脑内海绵状血管瘤(CA)
的显示能力,以探讨T2 技术对CA 的诊断价值。方法 对18 例CA 病人采用SE 和T2 序列进行MRI 检查,观察两者对CA 病灶的检测能力。结果 SE 序列共检出23 个CA 病灶。而T2 序列则比前者多发现20 个CA 病灶。T2 序列能更准确识别邻近蛛网膜下腔的皮层下和缺血灶附近的小CA 病灶。结论 CA 病人MRI 检查时,常规SE
序列与T2 相结合,能更全面准确地提供诊断信息。 |

| Purpose To find out the efficacy of gradient echoT2WI ( T2) sequence in identification of cerebral angioma
(CA) . Methods Conventional spin echo (SE) and T2 sequence were applied in MRI examination 18 patients with CA.Results 23 CA lesions were found out by SE sequence. T2 sequence permitted analyze 20 other lesions that were not obvious on SE sequence. In comparison with SE sequence , T2 was more capable in detecting small CA lesion adjacent to subarachnoid space and infarction lesion. Conclusion Supplemental T2 sequence increases the sensitivity of MRI in CA. |
