Intravenous cholangiography with helical CT: comparison with endoscopic retrograde cholangiography.

Abstract

Helical CT cholangiography may be a clinically useful method for visualization of the biliary tree in some patients with suspected biliary disease with normal bilirubin levels and in patients in whom attempts at ERC fail.

Helical CT in the Examination of Bile Duct Obstruction

“…Recent reports on a combination of i.v. cholangiography and helical CT have suggested 3-D reformats as a useful method in the case of patients with suspected biliary duct disease, especially if ERCP fails, or when laparoscopic s. LAHDE surgery is planned (7,14,15). 3-D images without intrabiliary contrast have also been suggested as a useful adjunct to the other imaging methods to demonstrate complex anatomical relationships (3).…”

“…There are recent reports of the application of 3-D CT reformats in the imaging of the biliary ducts (3,7,14,15) while the value of 2-D reformats in biliary duct disorders has not received attention in the literature. This retrospective analysis was performed in order to evaluate the efficacy of helical CT with 2-D multiplanar reformats in detecting the cause of bile duct obstruction, especially as a supplement to ultrasonography (US).…”

Management of Bile Duct Stones in the Era of Laparoscopic Cholecystectomy

“…Intravenous cholangiography fell into disuse over a decade ago due to poor sensitivity and concerns over contrast reactions, however some workers have recently reported good results using intravenous cholangiography with conventional tomography as a noninvasive alternative for detecting BDS prior to LC [113]. Other potentially promising new imaging techniques include three-dimensional spiral CT cholangiography [114,115] and magnetic resonance cholangiography [116,117]. Amouyal et al [65] found endoscopic ultrasonography to be more accurate than both conventional US and CT in detecting BDS [65], and other workers have confirmed the diagnostic efficacy of this technique [63].…”

Helical CT cholangiography

“…The images obtained with HCT can be utilized to create maximum intensity projections (MIP), three-dimensional (3-D) shaded surface display (SSD) images, and multiplanar displays of the bile ducts and gallbladder (Figs. [1][2][3][4][5]. These images can be rotated on a television monitor, viewed, and photographed from any orientation [3].…”
