Image data of CBTs were collected on gray-scale, CDU, CTA, and MRA. (a) Gray scale ultrasound image of a Shamblin III CBT on sagittal section and (b) transverse section. Ultrasound imaging detects a clear boundary, solid and hypoechoic mass which located at the carotid bifurcation. (c) CDU images of the CBT with a richly vascular and (d) with inner low-resistance arterial spectrum. (e) Multi slice spiral CTA with 3D VR shows a solid high vascular mass, causing widening of the carotid bifurcation and infiltrating internal carotid artery. (f) MRA images shows the typical separation of the external and the internal carotid arteries of the CBT, with heterogeneous enhancement
