“…MRCP diagnostic accuracy, sensitivity and specificity are comparable to those reported in the literature (Calvo et al, [10], Huassein et al, [13], Boraschi et al, [9] Varghese et al, [14]) where sensitivity, specificity and diagnostic accuracy respectively range between 81-100%, 84-100% and 90-96%.…”

“…Boraschi et al, reported a specificity of over 90% [9]. In the literature, a sensitivity range of 20 to 80% is often documented [10]; these considerable differences in sensitivity among various case series are partially attributable to the impossibility of approaching the distal CBD and ampullary region in obese patients and patients with abdominal meteorism, as well as to the variability of the US technique applied.…”

“…In such cases, ES is a therapeutical procedure [11]. In our study, 32 patients by MRCP and 26 patients by ERCP were detected to have dilated bile ducts that could not be explained by any obstructive pathology such as stones or tumors, and ES was performed.…”

“…10% of the MRCPs and 5% of the ERCPs carried out in our country in the beginning of the 2000s were optimally successful [11]. In the 2010 plus years, MRCP can be carried out on all cases where clinicians deem it necessary without the need for sedation, and ERCP is carried out with success rates of up to 95% ( Table 1).…”

Purpose: The aim of this study was to compare magnetic resonance cholangiopancreatography (MRCP) with endoscopic retrograde cholangiopancreatography (ERCP) in diagnosing bile duct pathologies. Materials and Methods: We documented the data of 171 patients with both ERCP and MRCP between January 2009 and December 2010 at the Konya Education and Research Hospital. Results: Of the 171 patients, 100 (58.5%) were female and 71 (41.5%) were male. The median age was 63 (55 to 89). ERCP was used to diagnose bile duct stones in 102 (59%) patients, bile duct tumour in 14 (8%) patients, hydatic cysts opening up to the bile duct in 4 (2%) patients and bile duct stenosis in 3 (1.8%) patients. For the detection of bile duct stones, MRCP had a sensitivity of 92%, a specificity of 74% and a diagnostic accuracy of 83%. For bile duct tumours, MRCP had a sensitivity of 85%, a specificity of 98% and a diagnostic accuracy rate of 92%. Conclusion: In our centre, the results of MRCP and ERCP were similar for the last two years. However, MRCP was superior with respect to diagnosis as it was cheaper and non-invasive. Thus, ERCP should be preferred for therapeutic processes.

“…MRCP can provide imaging of the entire biliary tree proximal and distal to an obstruction, facilitating the diagnosis in cases in which the guidewire cannot be introduced due to stenosis and ERCP is non-diagnostic [2][3][4] . Offering a panoramic image, MRCP also provides detailed imaging of the entire biliary tree 5 , the position of the drainage catheter and pre-operative assessment 3,6 , especially in recognition of residual stones following cholecystectomy and assessment of stenosis in patients with bilio-enteric Common bile duct caliber suddenly reduced due to the mass causing the compression of the pancreatic head and the pancreatic duct appeared discontinued.…”

ÖzetBu çalışmanın amacı pankreatikobilier sistem patolojilerinin tespitinde manyetik rezonans kolanjiopankreatografinin (MRCP) duyarlılığı, tanıya katkısını belirlemek ve endoskopik retrograd kolanjiopankreatografi (ERCP) ile karşılaştırmaktır.ERCP günümüzde pankreatikobilier sisteminin değerlendirilmesi için halen altın standart olarak kabul edilir, ancak MRCP safra yollarının değerlendirilmesinde güvenli ve noninvaziv olması nedeniyle tanısal amaçlı ERCP'ye alternatif olabilir. MRCP'nin klinik kullanıma girmesiyle, son zamanlarda özellikle tanısal amaçlı ERCP incelemeleri sayısında azalma eğilimi görülmüştür. Klinik ve laboratuar bulguları ile obstrüktif safra yolu patolojisi düşünülen ancak ultrasonografi ve/veya bilgisayarlı tomografi bulguları kliniği açıklamada yetersiz kalan 51 hasta üzerinde yapılmıştır. Koledok taşı, koledok dilatasyonu, koledok darlıkları ve IHSY dilatasyonu tanısında MRCP'nin duyarlılık, özgüllük, pozitif prediktif değer ve negatif prediktif değeri değerlendirildi. MRCP'nin tüm safra yolları patolojilerinin değerlendirilmesinde duyarlılık, özgüllük, pozitif ve negatif prediktif değerleri sırasıyla, %85.0, %50.0, %89.4 ve %40.0 idi. MRCP deneyiminin artması ve geniş serili çalışmalarla sonuçlarda ilerleme sağlanacak ve tanısal başarı artacaktır. AbstractThe aim of this study was to determine the sensitivity and diagnostic contribution of magnetic resonance cholangiopancreatography (MRCP) in identifying pancreaticobiliary system pathologies and compare with endoscopic retrograde cholangiopancreatography (ERCP). ERCP is currently considered the gold standard for the evaluation of the pancreaticobiliary system. However, MRCP is a safe, non-invasive diagnostic alternative to ERCP. By the introduction of MRCP into clinical use, there has recently been a tendency of decrease especially in the number of ERCP evaluations performed only for diagnostic purposes. 51 patients were included in the study with clinical and laboratory findings suggestive of obstructive biliary tract pathology, but in whom the ultrasound and/or computerized tomography (CT) findings were inconclusive. Sensitivity, specificity, positive and negative predictive value of MRCP in the diagnosis of common bile duct stone, common bile duct dilatation, common bile duct strictures and intrahepatic bile duct (IHBD) dilatation were assessed. The sensitivity, specificity, and positive and negative predictive values of MRCP for the assessment of all biliary tract pathologies were 85.0%, 50.0%, 89.4%, and 40.0%, respectively. An increase in the experience of the MRCP examination and studies with larger series may provide the improvement in results; thus, an increase in diagnostic success may be established.
