Abdomen

The Abdominal Division of the Department of Radiology offers a full range of imaging services to evaluate known or suspected disorders of the abdomen and pelvis. The Division is subdivided into four separate subdivisions: Gastrointestinal Radiology, Genitourinary Radiology, Abdominal Computed Tomography (CT) and Abdominal Magnetic Resonance Imaging (MR).

The Gastrointestinal Radiology subdivision provides the standard examinations for contrast evaluation of the gastrointestinal tract, including double contrast and biphasic techniques, enteroclysis and per-oral pneumocolon examinations. Three phase pharyngograms for swallowing disorders and defecography for incontinence are also performed. Interpretation of all ERCP studies is provided.

The Genitourinary Radiology subdivision performs the standard contrast examinations including excretory urography, cystography, voiding cystourethography and retrograde urethography. All hysterosalpingography is performed in conjunction with faculty from the Department of Obstetrics and Gynecology, and the images are interpreted by the Abdominal Division.

The Abdominal CT subdivision, in addition to performing standard examinations of the abdomen and pelvis for detection of the full spectrum of inflammatory and neoplastic conditions, is in the forefront of development and evaluation of cutting edge advances in CT technology. The eight current CT scanners use the helical technology, most with the newest multidetector-row platform. Some of the advanced techniques developed and now used on a daily basis include 3D CT angiography for renal transplant donors and evaluation of abdominal aortic aneurysms for stent graft placement, multiphasic imaging of pancreatic and hepatic neoplasms, and CT densitometry for differentiating benign from malignant adrenal masses.

The Abdominal MR subdivision provides a full range of MR examinations of the abdomen and pelvis including standard evaluation of known or suspected masses in the liver, spleen, pancreas, adrenal glands and kidneys. Characterization of known or suspected uterine anomalies is commonly performed. MRCP studies of the biliary and pancreatic ducts and MR urography are a growing part of our MR activities. In conjunction with the Cardiovascular and Interventional Radiology Division, the Abdominal Division performs and interprets the MR angiography studies of the abdominal and pelvic vasculature. All clinical MR scanners are state-of-the-art 1.5 Tesla units.
