Figure 4

(a) 22-year-old male with history of CF presents with recurrent bouts of sharp RUQ abdominal pain. Findings: coronal MRCP maximum intensity projection (MIP) image of the biliary system showing intense T2 signal of a tubular structure in the gallbladder fossa measuring 2.5 cm in length and 0.8 cm in width consistent with microgallbladder. The cystic duct is patent. The intrahepatic ducts are not well visualized on this MIP projection. The pancreatic duct and common bile duct are patent and normal in caliber

(b) 22-year-old male with history of CF presents with recurrent bouts of sharp RUQ abdominal pain. Findings: axial non-contrast-enhanced T1-weighted sequence MRI image demonstrating small gallbladder measuring 2.5 cm in length and 0.8 cm in width consistent with microgallbladder
