Liver Transplant Recipients

Purpose: To evaluate the ability of multi-detector row computed tomography angiography (CTA) in detecting hepatic artery complications in the follow-up of liver transplant patients, performing volume-rendering as reconstruction technique. Material and Methods: The anatomy of hepatic artery was studied in 27 liver transplant recipients with a four-row CT scanner using the following parameters: collimation, 1 mm; slice width, 1 mm; table feed, 6–8 mm/s; spiral reconstruction time, 0.5 s; reconstruction interval, 0.5 mm; mAs, 160; kVp, 120. Before the study, the patients received 1000 ml of water as oral contrast agent to produce negative contrast in the stomach and the small bowel. A non-ionic contrast medium was infused intravenously at a rate of 5 ml/s with a bolus tracking system. Volume-rendering of hepatic artery was performed with the 3D Virtuoso software. Results: The celiac trunk, the hepatic artery, and the right and left hepatic arteries were successfully displayed in high detail in all patients. Side branches, including small collaterals, and hepatic artery anastomosis could also be readily visualized. Volume-rendered CTA detected six hepatic artery stenoses, two hepatic artery thromboses, and two intrahepatic pseudoaneurysms. In two cases, CT detected hepatic artery stenosis with a diameter reduction of less than 50%, while digital subtraction angiography showed a normal artery. Conclusion: Volume-rendered multi-detector CTA is a promising non-invasive technique, since it allows images of high quality to be generated with excellent anatomical visualization of the hepatic artery and its complications in liver transplant recipients.

3D Volume Rendering

Two cases of mandibulofacial dystostosis are presented in order to describe the features associated with the condition. Computed tomography (CT) is frequently performed on these patients to aid in surgical planning. 3D volume rendering provides the opportunity to discuss the imaging features of this uncommon condition.

A dog was referred to Alta Vista Animal Hospital with a porcupine quill penetrating the right ventricle. The presenting complaint was tachypnea and dyspnea secondary to bilateral pneumothorax. Computed tomography revealed bilateral pneumothorax without evidence of quills. A median sternotomy was performed and the quill was removed. The dog recovered uneventfully. Quill injuries are common in dogs; however, intracardiac quill migration is rare. Dogs without evidence of severe cardiac injury secondary to intracardiac foreign bodies may have a good prognosis.
