目的 探讨CT各影像诊断方法对 脑发育性静脉畸形的诊断效果分析。方 法 选取2010年9月至2015年9月的20例 脑发育性静脉畸形患者，均行CT平扫、 CT血管造影、CT增强容积重建(VR)、CT MIP成像诊断并进行对比分析。结果 所 选取的20例脑发育性静脉畸形患者，CT 平扫可见19例患者颅内多发散在点片状 略高密度影，主要位于右侧额叶，边界 清楚，周围无水肿，确诊率达95%；CT 血管造影可见所有患者右侧额叶多发异 常强化血管影，呈“海蛇头样”，周围 无水肿，确诊率达100%；CT增强容积重 建(VR)可见所有患者右侧额叶多发异常 血管影，最终汇入下矢状窦，确诊率达 100%；CT MIP成像清楚显示所有患者的 粗大静脉血管汇入下矢状窦，血管未见 血栓，确诊率达100%；由此可见诊断结 果与临床病理确认结果相比，差异无统 计学意义。CT血管造影、VR、CT MIP成 像的诊断率高于CT平扫。结论 诊断发现 脑发育性静脉畸形具有典型的影像学特 点，所以CT各影像学诊断方法在脑发育 性静脉畸形的诊断中具有非常高的应用 价值，可以作为脑发育性静脉畸形的重 要检查方法。

Objective To explore the diagnostic effect of CT imaging diagnosis methods on cerebral developmental venous malformations. Methods 20 cases of cerebral developmental venous malformations were selected from September 2010 to September 2015. All patients underwent CT plain scan, CT angiography, CT enhanced volume reconstruction (VR) and MIP CT imaging. Results The selected 20 cases of patients with cerebral developmental venous malformation, CT scan showed 19 cases of patients with intracranial spread in the patchy slightly high density, mainly located in the right frontal lobe, clear boundary, peripheral edema, diagnosis rate was 95%. CT angiography showed the right frontal lobe all patients with multiple abnormal enhanced vessels, a "sea snake head", without peripheral edema, diagnosis rate was 100%. CT enhanced volume reconstruction (VR) visible all right frontal lobe in patients with multiple abnormal vessels, then into the inferior sagittal sinus, diagnosis rate was 100%. CT MIP imaging clearly showed thick veins in all patients into the inferior sagittal sinus, no vascular thrombosis, diagnosis rate was 100%, the diagnostic results and clinical pathology confirmed the results compared to the difference was not statistically significant. The diagnostic rate of CT angiography, VR and MIP CT imaging was higher than that of CT plain scan. Conclusion The diagnosis of cerebral developmental venous anomaly has typical imaging features, so the CT imaging diagnosis methods in cerebral developmental venous anomaly diagnosis has very high application value and is an important inspection method.
