Magnetic resonance cholangiopancreatography in 3 Tesla: 2D MRCP versus 3D MRCP in diagnostic evaluation with special reference to different acquisition and reconstruction planes (original) (raw)
2015, The journal of global radiology
MAGNETIC resonance cholangiopancreatography (MRCP) is an established technique for the evaluation of intra-and extra-hepatic bile ducts in patients with known or suspected hepatobiliary disease [1]. It is considered a reliable, non-invasive alternative to diagnostic endoscopic retrograde cholangiopancreatography (ERCP) [2,3]. Since the first description by Wallner and colleagues in 1991 [4], different acquisition techniques have evolved. Most current MRCP techniques are based on heavily T2-weighted fast spin echo (FSE) pulse sequences, which yield a luminal image of the bile ducts that is based on the inherent signal of slowflowing or stationary bile. Both single-shot projections and multislice techniques are available [5], with the latter being distinguished into 2D-[6] and 3D-techniques [7]. Single-shot projections are preferred in individuals who are unable to hold their breath, such as severely sick patients or small children [7]. 3D-imaging techniques provide better image quality compared to 2D-sequences [1,8,9], even though the combination of different MRCP sequences has proven to be valuable in the assessment of bile duct anatomy and pathology [10]. 3D FSE sequences are usually acquired with the slab in coronal orientation.

Magnetic resonance cholangiopancreatography (MRCP) is an established technique for the evaluation of intra- and extrahepatic bile ducts in patients with known or suspected hepatobiliary disease. However, the ideal acquisition and reconstruction plane for optimal bile duct evaluation with 3D technique has not been evaluated. The purpose of our study was to compare different acquisition and reconstruction planes of 3D-MRCP for bile duct assessment. 34 patients (17f/17 m, mean age 41y) referred for MRCP were included in this prospective IRB-approved study. Respiratory-triggered 3D-T2w-MRCP sequences were acquired in coronal and axial plane. Coronal and axial MIP were reconstructed based on each dataset (resulting in two coronal and two axial MIP, respectively). Three readers in two sessions independently assessed the MIP, regarding visualization of bile ducts and image quality. Results were compared (Wilcoxon test). Intra- and interobserver variability were calculated (kappa-statistic)...
Evaluation of Intrahepatic Bile Duct Variations in Magnetic Resonance Cholangiopancreatography
Nepalese Journal of Radiology, 2020
Introduction: A detailed knowledge of normal branching pattern of intrahepatic bile duct and their variations is of utmost importance for any liver or biliary tract surgery to avoid severe post-surgery complications and morbidity. The objective of this study was to evaluate variations of intrahepatic bile ducts in Magnetic Resonance Cholangiopancreatography (MRCP) examinations in Nepalese population.Methods: This quantitative, cross sectional study was performed in patients referred for MRCP examinations for various clinical indications to Tribhuvan University Teaching Hospital, Maharajgunj, Nepal. Data were collected for a period of four months from August to November 2019 after IRB approval. Convenience sampling was employed and a total of 90 examinations were included. Data were obtained from the 1.5T Magnetom Amira Siemens MRI scanner. The 3D MRCP images were visually analyzed and classified into 7 Types according to the classification given by Choi et al.Results: In our study 4...
Magnetic resonance cholangiography: past, present and future: a review
European review for medical and pharmacological sciences, 2010
Magnetic resonance cholangio-pancreatography (MRCP) is a valuable method for the evaluation of biliary and pancreatic diseases and a valuable alternative to endoscopic retrograde cholangiopancreatography (ERCP). It is noninvasive and does not require the use of contrast material or ionizing radiation. Since its introduction in 1991, this technique has significantly improved in spatial resolution, now allowing the accurate assessment of the major bilio-pancreatic diseases. MRCP is commonly performed with heavily T2-weighted sequences in order to highlight static fluids, as those contained in dilated pancreatic and biliary ducts. Newest MR equipments allow to perform MRCP within 10-15 minutes, due to the availability of ultra-fast sequences. Currently, MRCP is widely performed as a primary imaging modality for the assessment of obstructive jaundice and other benign or malignant bilio-pancreatic ducts abnormalities. The primary MRCP application is the evaluation of biliary obstructions...

Magnetic resonance cholangiopancreatography (MRCP) is non invasive imaging technique able to provide projection images of the bile and pancreatic ducts. Using breath--hold and non-breath--hold acquisition techniques, have been employed in order to obtain MRCP images. Clinical applications of MRCP are evaluated from presenting references and from personal experience. The main indication for MRCP imaging was in evaluation of common bile duct obstruction, with aim of present the level, and its cause. The utility of conventional MR images to MRCP in the malignant lesion is already discussed. At the end, the utility of MR pancreatography in evaluation of the patients with pancreatic disease is discussed from both the literature and personal experiences. The clinical indications to perform ERCP in patients with pancreatic cancer may include palliative stent placement in patients with known non-resectable pancreatic carcinoma invading the common bile duct; obtaining tissue material in pati...

Breath-hold MR cholangio-pancreaticography using the RARE method was evaluated as a noninvasive alternative to direct cholangio-pancreaticography in 30 healthy volunteers and in 30 patients with various diseases of the respective duct systems. In contrast to 3D MR cholangiography, RARE MRCP generates projection images requiring a 4-s acquisition time and no postprocessing. Diagnostic information gained from the cholangio-pancreaticograms was fully equivalent to that of conventional x-ray imaging by invasive procedures. Additional information was gained whenever endoscopic access was impossible and/or cystic malformations were present.
