Diagnosis of a vertebral artery loop in the transverse canal, suggested by a CT scan image, is dependent mainly on results of angiography (preferably computer assisted and by the venous route). This lesion is a differential diagnosis of a neuroma, when the cervical intervertebral foramen is enlarged.
CT扫描图像提示的横突孔内椎动脉袢的诊断主要依赖于血管造影结果（最好是计算机辅助且经静脉途径）。当颈椎椎间孔扩大时，这种病变需与神经瘤进行鉴别诊断。
