“…Thin section axial and coronal plane images as well as thick slabs in radiating coronal planes, should be acquired. Because neonates and infants usually have irregular breathing with ranging respiratory amplitude, 3-D FSE imaging with respiratory triggering may not be possible in many of these patients [27]. High cost, limited availability and time required for scanning are problems with MRCP, but it has the capacity to provide anatomic and pathologic details of biliary tract as demonstrated in our series.…”

Background: Hepatobiliary and pancreatic disorders in children are infrequent and include Duct union (APBD -union), Extra hepatic biliary atresia (EHBA), Caroli's disease, primary sclerosing cholangitis, pancreas divisum and pancreatic duct abnormalities. A range of investigations have been used for evaluation of these disorders in children ranging from sonography, HIDA Scan computed tomography, ERCP, Cholangiography and MRCP. Among these MRCP is a non-invasive investigation which has the potential to delineate the hepatobiliary pancreatic ductal system preoperatively to help surgeon in diagnosis and operative planning

“…No major extra scan time is needed. Therefore other indications for MRCP are bile duct lesions, primary sclerosing cholangitis, common bile duct cysts, congenital bile duct atresia and pancreatic duct evaluation in chronic pancreatitis [16, 17, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30]. Potential pitfalls of MRCP are pneumobilia, tortuous common bile duct, and compression of the hepatic duct by the right hepatic artery and the origin of the cystic duct mimicking CBD stones (fig.…”

Background/Aims: The diagnostic potential of magnetic resonance cholangiopancreaticography (MRCP) has improved as a result of evolving technique. MRCP has the advantage of negligible morbidity and mortality in contrast to endoscopic retrograde cholangiopancreatography (ERCP). This study was performed to evaluate MRCP as a replacement for diagnostic ERCP for the suspicion of common bile duct (CBD) stones. Methods: From 1998 to 2001, MRCP was performed in 202 patients with a suspicion of CBD stones based on medical history (MH), cholestatic liver function tests (CL), both MH and CL or other reasons. ERCP was performed in all patients where MRCP indicated the presence of CBD stones and in those patients with a persistent strong clinical suspicion for CBD stones despite a negative MRCP. Results: In 25 patients, MRCP suggested CBD stones which were proven with ERCP in 24 patients. Despite a negative MRCP, 27 patients had a subsequent ERCP. None of these patients appeared to have CBD stones. In this group, MRCP resulted in 100% sensitivity and 96% specificity in detecting CBD stones. Follow-up of all patients revealed 5 more patients with persistent clinical suspicion or cholestatic liver function values. Assuming CBD stones in these patients, MRCP had a sensitivity of 83 % and a specificity of 99% for this diagnosis. Conclusion: In the case of CBD stone suspicion, MRCP should be the diagnostic procedure of choice.

“…Initially, MRCP was extremely limited in its diagnostic accuracy and used sparingly in extremely cooperative patients. The advent of respiratory trigger and non-breath holding techniques gradually enabled MRCP use in less cooperative patients, especially children [43][44][45][46] . Concurrently, rapid imaging techniques including HASTE/single-shot FSE/single-shot turbo spin echo (TSE) decreased image acquisition time to 2-5 s. Today, MRCP is utilized to study the biliary system in almost all populations [47,48] .…”

AIM:To determine the merits of magnetic resonance cholangiopancreatography (MRCP) as the primary diagnostic test for choledochal cysts (CC's). METHODS:Between 2009 and 2012, patients who underwent MRCP for perioperative diagnosis were identified. Demographic information, clinical characteristics, and radiographic findings were recorded. MRCP results were compared with intraoperative findings. A PubMed search identified studies published between 1996-2012, employing MRCP as the primary preoperative imaging and comparing results with either endoscopic retrograde cholangiopancreatography (ERCP) or operative findings. Detection rates for CC's and abnormal pancreaticobiliary junction (APBJ) were calculated. In addition detection rates for clinically related biliary pathology like choledocholithiasis and cholangiocarcinomas in patients diagnosed with CC's were also evaluated. RESULTS:Eight patients were identified with CC's. Six patients out of them had type Ⅳ CC's, 1 had type I and 1 had a new variant of choledochal cyst with confluent dilatation of the common bile duct (CBD) and cystic duct. Seven patients had an APBJ and 3 of those had a long common-channel. Gallstones were found in 2 patients, 1 had a CBD stone, and 1 pancreatic-duct stone was also detected. In all cases, MRCP successfully identified the type of CC's, as well as APBJ with ductal stones. From analyzing the literature, we found that MRCP has 96%-100% detection rate for CC's. Additionally, we found that the range for sensitivity, specificity, and diagnostic accuracy was 53%-100%, 90%-100% and 56%-100% in diagnosing APBJ. MRCP's detection rate was 100% for choledocholithiasis and 87% for cholangiocarcinomas with concurrent CC's. CONCLUSION:After initial ultrasound and computed tomography scan, MRCP should be the next diagnostic test in both adult and pediatric patients. ERCP should be reserved for patients where therapeutic intervention is needed.© 2013 Baishideng.

This is the first literature review of published studies discussing MRCP as a diagnostic modality for choledochal cysts. This review further outlines how recent imaging techniques have improved diagnostic accuracy of MRCP in diagnosing choledochal cysts and their associated anatomic variants. Advantages, disadvantages and contraindication for MRCP with respect to endoscopic retrograde cholangiopancreatography are also discussed.
