    Notes: Abstract. The purpose of this study was to evaluate the role of radiological techniques in the diagnosis and management of developmental intrahepatic shunts. Hepatic vascular fistulae are recognised sequelae of liver trauma and intrahepatic tumours. However, there are rare developmental malformations which may present in childhood or later life and which may carry life-threatening complications. Retrospective analysis of clinical and radiological data was carried out in 24 patients. Anomalies evaluated were: (a) direct communication between hepatic artery and hepatic veins; (b) congenital hepatoportal arteriovenous malformations; and (c) congenital portocaval anastomosis with persistent flow through the ductus venosus. Although rare, the prompt recognition of these vascular anomalies allows early surgical or radiological intervention and reversal of the haemodynamic complications.

    Notes: Abstract. This article reviews the application of magnetic resonance imaging (MRI) to study the gastrointestinal (GI) tract. A summary of the current MRI techniques is included, emphasizing the choice of pulsing sequences, imaging plane, surface coils and intravenous and oral contrast agents for each of the different segments of the GI tract. The multiple available oral contrast agents are reviewed, including the role of both positive and negative. Finally, the major clinical applications of MRI in the GI tract are discussed by major disease categories (congenital abnormalities, inflammatory disease and benign and malignant neoplasms). The latter is further subdivided by GI tract segments such as esophagus, stomach, small bowel and colon.

    Notes: Abstract. The rectum has become the most successful area of the gastrointestinal tract to be studied with MRI. Its anatomical location, fixed in the pelvic fat, and its lack of peristalsis, make it an ideal organ to be scanned with MRI. In addition, MRI allows a direct sagittal and coronal display, of key importance to colorectal surgeons whose terminology and approach are based on the coronal plane. The sagittal plane allows the depiction of the relation of the rectum to the sacrum, uterus and prostate, with detail not available by other imaging techniques, and the use of endorectal coils allows excellent demonstration of the rectal wall. Although MRI has been used primarily to study rectal carcinoma, other diseases, congenital, inflammatory and vascular in origin, can be studied using the correct technique.
