    MR-cholangiopancreatography (MRCP) images
     

    Panoramic (a), right (b) and left (c) lobe MRCP images with thick-slab (b) and MIP-reformatted thin-slice (a,c) techniques. Innumerable scattered, peripheral and intrahepatic liver lesions with high signal intensity...

     
    Area of Interest: Biliary Tract / Gallbladder; Imaging Technique: MR; Procedure: Cholangiography; Special Focus: Cysts;

    MRCP shows innumerable scattered, peripheral and intrahepatic liver lesions in both lobes, tiny or centimetric in size, with high-signal intensity approaching that of static fluid, slightly irregular contours, without...

    Area of Interest: Biliary Tract / Gallbladder; Imaging Technique: MR; Procedure: Cholangiography; Special Focus: Congenital;

    On unenhanced axial T1-weighted images (e..h in cranio-caudal order) the innumerable liver lesions are somewhat less conspicuous than on T2-weighted scans, with fluid-like low signal intensity.

     
    Area of Interest: Biliary Tract / Gallbladder; Imaging Technique: MR; Procedure: Cholangiography; Special Focus: Congenital;

    On unenhanced axial T1-weighted images the innumerable scattered liver lesions show fluid-like signal intensity, slightly irregular contours or isointense mural nodules (arrowhead in h).
