Therefore, only 13 studies used appropriate methods of sample selection.…”

“…Because T2-weighted MR cholangiography is usually used in patients with jaundice and patients with biliary complications, a second limitation was that our patient population was not equal to the patient population usually evaluated with T2-weighted MRCP. 16,17 However, our study was an initial trial to evaluate the eŠects on T2-weighted MRCP, and it was proper to evaluate a healthy population.…”

Purpose: Gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid (Gd-EOB-DTPA) is a recently developed liver-speciˆc contrast agent for magnetic resonance (MR) imaging that is excreted equally via the kidneys and the biliary system. To our knowledge, its eŠects on T 2 -weighted MR cholangiopancreatography (MRCP) images have not been explored. Acquisition of the hepatobiliary phase is recommended 20 min after administration of Gd-EOB-DTPA. Examination time cannot be extended if the contrast does not take eŠect on T 2 -weighted MRCP within 20 min after administration.We attempted to assess the change in signal of T 2 -weighted MRCP by excretion of Gd-EOB-DTPA.Methods: Between March and July 2008, 40 patients (15 women, 25 men; mean age 70.8 years) were examined with abdominal MR imaging. T 2 -weighted MRCP was performed before and 10 and 20 min after administration of Gd-EOB-DTPA. We analyzed signal intensity of the bile duct, gallbladder, cystic duct, and pancreatic duct on MRCP for changes in intensity.Results: T 2 -weighted MRCP 20 min after contrast administration showed loss of signal of the bile duct (intrahepatic bile duct in all cases, upper extrahepatic duct in 36 [90z], middle extrahepatic duct in 33 [85z], and lower extrahepatic duct in 26 [67z]), the gallbladder in 23 cases (72z), and the cystic duct in 25 (64z). This signal change increased with time. We observed no change in signal of the pancreatic duct.Conclusion: T 2 -weighted MRCP sequences should not be obtained after administration of Gd-EOB-DTPA because this contrast agent decreases signal intensity of the biliary structure on these images.
