From: Intra-arterial versus intra venous contrast-enhanced computed tomography of the equine head
Transverse pre-contrast (a), IA post-contrast (b) and IV post-contrast (c) CT images at the level of the temporo-mandibular joints (right is to the left and dorsal is to the top). a The visibility of the vascular structures are less clear definite compared to the post-contrast images, especially the smaller arterial structures (A and T) are more difficult to distinguish from the surround soft tissue. b Bilateral contrast-enhancement after unilateral left-sided intra-arterial contrast injection is clearly delineating the vascular structures; contrast streaming is seen in the left maxillary vein. c Homogenous, bilateral contrast-enhancement of the arterial and venous vascular structures after intra-venous contrast injection. TMJ: temporomandibular joint; H: pituitary gland; A: maxillary artery; V: maxillary vein; T: truncus linguofacialis; L: linguofacial vein
