摘　　要：目的:探讨CTA多种后处理方法在口腔颌面部动静脉畸形(AVM)诊断中的价值。方法:分析经手术病理证实的8例口腔颌面部AVM的MSCT表现,着重分析其CTA表现。结果:8例患者中,发生于软组织内5例,下颌骨3例。5例软组织者,边界均不清楚,无钙化,1例肿瘤内可见出血,增强扫描明显强化。3例下颌骨者,均表现为明显膨胀性溶骨性骨质破坏,增强扫描明显强化。CTA通过VR及MIP后处理能够清楚地显示病灶的供血动脉及引流静脉。结论:CTA通过不同的三维重建方法能全方位、直观、详细地显示口腔颌面部AVM病灶及血管情况。Objective： To determine the value of computed tomography angiography （CTA） in the diagnosis of arteriovenous malformations in the oral and maxillofacial regions using imaging reformating techniques. Methods： A total of 8 patients with surgically and pathologically proved arteriovenous malformations in the oral and maxillofacial regions were enrolled. The imaging features of the lesions especially the CTA findings were retrospectively analyzed. Results： In the 8 patients, lesions were located in soft tissues in 5 patients and mandible in 3 patients. All the 5 patients lesions located in soft tissues had an ill- defined boundary without calcification. Hemorrhage was seen in 1 patient. All the 5 patients had obvious enhancement. An obvious expansive osteolytic lesions was found in 3 patients located in mandible. Also, an obvious enhancement was seen in the 3 patients. Through reformating techniques such as VR and MIP, CTA could well detect the feeding and draining vessels of the lesions. Conclusion： MSCT can directly, comprehensively show the lesion details and vessels of AVM located in oral and maxillofacial by means of different 3D image reformating technique.
