Abstract 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.
