BACKGROUND Magnetic resonance cholangiography (MRC) is a non-invasive method for imaging biliary ducts. When used to exclude common bile duct (CBD) stones, MRC may obviate the need for intra-operative cholangiography (IOC). In this prospective study, MRC and IOC were compared for the diagnosis of suspected stones of the CBD. METHODS Thirty patients with(More)
This study was designed to determine the effects of intravenous fentanyl on magnetic resonance cholangiopancreatography image quality in the treatment of pancreaticobiliary disorders. Forty consecutive patients referred for the evaluation of pancreaticobiliary disorders underwent magnetic resonance cholangiopancreatography in the coronal and oblique–coronal(More)
BACKGROUND Medical X-rays are the largest man-made source of public exposure to ionizing radiation. While the benefits of Computed Tomography (CT) are well known in accurate diagnosis, those benefits are not risk-free. CT is a device with higher patient dose in comparison with other conventional radiation procedures. OBJECTIVE This study is aimed at(More)
BACKGROUND The most efficient application of ionizing radiation is serving medical purposes and using this radiation has caused people to learn that artificial sources of radiation exposure among these resources can be of highest exposure rate. OBIECTIVE The present study is aimed at initially establishing a baseline for local-reference dose level in(More)
