目的 讨论CT和核磁共振成像在 颅内海绵状血管瘤的诊断价值。方法 回 顾分析我院2014年1月-2015年12月期间接 收的17例颅内海绵状血管瘤患者的检查资 料，均进行CT和MRI检查，并分析病灶处 CT和MRI检查的影像特征和诊断结果。采 用CT、MRI、CT联合MRI的方法，对照三种 不同方法的灵敏度、特异度、准确率和 检出率。结果 单独采用CT和MRI诊断的灵 敏度分别为58.8%和76.4%，特异度分别 为64.7%和76.4%，准确率分别是41.2%和 76.5%，检出率是47.1%和82.4%，采用CT 联合MRI的诊断结果灵敏度是88.2%，特异 度是82.4%，准确率和检出率分别是88.2% 和94.1%，准确率和检出率差异具有统计 学意义(P<0.05)。结论 颅内海绵状血管 瘤通过CT和核磁共振检测，具有特征性影 像学表现，结合CT和MRI可提高准确率。

Objective To discuss CT and MRI diagnostic value of intracranial cavernous angiomas (ICA). Methods 17 cases with ICA data in our hospital during January 2014 to December 2015 were retrospectively analyzed, both CT and MRI examination were done. Adopt CT, MRI, CT and MRI methods and compare three different methods of sensitivity, accuracy and detection rate, specific degrees. Results The single CT or MRI diagnostic sensitivity rate of ICA were 58.8% and 76.4% specificity rate were 64.7% and 76.4%, the accuracy rate were 41.2% and 76.5%, detection rate is 47.1% and 82.4%, respectively. Otherwise, by using CT combine MRI the diagnosis sensitivity rate and specificity rate were 88.2%, 82.4%, accuracy rate and detection rate were 88.2% and 94.1%, which were differences statistically significant (P<0.05). Conclusion There were characteristic feature of ICA in CT and MRI, which can improve the accuracy by combing CT and MRI.
