“…Although US and CT often provide sufficient information in patients with bile duct obstruction due to malignant tumors, they lack sensitivity in the detection of choledocholithiasis [1][2][3][4][5][6]. The IVC technique was almost abandoned in the 1980 s but has gained renewed interest in the era of laparoscopic surgery, because it can detect bile duct calculi with sufficient sensitivity and may also delineate morphologic variations in the nonobstructed biliary tree [7,8]. As a drawback, IVC cannot be used in the presence of impaired hepatobiliary function or stasis, as it depends on hepatic excretion of contrast material.…”

MR cholangiopancreatography: technique, potential indications, and diagnostic features of benign, postoperative, and malignant conditions

The objective of this article is to review technical aspects, discuss potential clinical indications for MR cholangiopancreatography (MRCP) and demonstrate the spectrum of diagnostic findings in benign, postoperative, and malignant conditions. We describe our current imaging protocol in comparison with other available techniques. Using a non-breath-hold, heavily T2-weighted fast-spin-echo (FSE) sequence with or without respiratory gating we obtained coronal and axial source images and maximum intensity projections (MIPs) in 102 patients with suspected abnormalities of the biliary or pancreatic ducts. Based on this series we demonstrate the diagnostic appearance of a variety of benign, postoperative, and malignant conditions of the biliary and pancreatic ducts and discuss potential clinical indications for MRCP. The non-breath-hold FSE technique enables a consistent image quality even in patients who cannot cooperate well. Respiratory gating increased the rate of diagnostic examinations from 79 to 95 %. Acquisition of coronal and axial source images enables detection of bile duct stones as small as 2 mm, although calculi that are impacted and not surrounded by hyperintense bile may sometimes be difficult to detect. The MIP reconstructions help to determine the level of obstruction in malignant jaundice, delineate anatomical variants and malformations, and to diagnose inflammatory conditions, e. g., sclerosing cholangitis, the Mirizzi syndrome and inflammatory changes in the main pancreatic duct. The MRCP technique also correctly demonstrates the morphology of bilio-enteric or bilio-biliary anastomoses. Because MRCP provides sufficient diagnostic information in a wide range of benign and malignant biliary and pancreatic disorders, it could obviate diagnostic endoscopic retrograde cholangiopancreatography (ERCP) in many clinical settings. The ERCP technique may be increasingly reserved for patients in whom nonsurgical interventional procedures are anticipated.

To identify patients with common bile duct stones, all patients considered for laparoscopic cholecystectomy in this unit undergo intravenous cholangiography (IVC) with tomography and, more recently, operative cholangiography. To date 100 consecutive patients with symptomatic gallstones have undergone laparoscopic cholecystectomy with no specific exclusion criteria. Eight patients of 100 were found to have duct stones on IVC with one false-positive. These IVC data were compared with data from 52 patients who also had operative cholangiograms performed. One stone was detected on operative cholangiography that was not identified on IVC. No additional information was gained from operative cholangiography. These data suggest that preoperative IVC is adequate for the detection of duct stones in patients considered for laparoscopic cholecystectomy.
