Figure 1a. Patient 1. (a) Coronal MR image obtained with a thin-section half-Fourier RARE sequence ( /95 [effective]; flip angle, 150°) shows two cystic duct calculi (arrows). (b) Maximum intensity projection from coronal three-dimensional volumetric-interpolated T1-weighted gradient-echo image (4.2/1.6; flip angle, 12°) obtained 45 minutes after injection of mangafodipir trisodium shows the enhanced extrahepatic duct, but the gallbladder cannot be visualized. (c) Anterior hepatobiliary scintigraphic image obtained 60 minutes after injection of IDA demonstrates visualization of the extrahepatic duct (thin arrows) and small bowel (thick arrows) but fails to depict the gallbladder.

Figure 2a. Patient 6.
(a) Coronal MR image obtained with a thin-section half-Fourier RARE sequence ( /95 [effective]; flip angle, 150°) shows signal void lesions (arrows) in the cystic duct that are suspicious. However, they cannot be differentiated from a tortuous normal cystic duct. (b) Maximum intensity projection from coronal three-dimensional volumetric-interpolated T1-weighted gradient-echo MR image (4.2/1.6; flip angle, 12°) obtained 60 minutes after injection of mangafodipir trisodium shows the enhanced extrahepatic duct (arrows), but the gallbladder is not enhanced. (c) Anterior hepatobiliary scintigraphic image obtained 50 minutes after injection of IDA demonstrates visualization of the extrahepatic duct (thin arrow) and small bowel (thick arrows), but it does not depict the gallbladder.

Figure 3a. Patient 8. (a) Coronal MR image obtained with a thin-section half-Fourier RARE sequence ( /95 [effective]; flip angle, 150°) shows distended gallbladder (black and white long thick arrows) and ascites (short thick arrows). The gallbladder is angulated (thin arrow) between the neck and body. There is no calculus in the gallbladder or bile duct. (b) Coronal three-dimensional volumetric-interpolated T1-weighted gradient-echo source MR cholangiographic image (4.2/1.6; flip angle, 12°) obtained 60 minutes after injection of mangafodipir trisodium shows the enhanced extrahepatic duct and neck portion (black arrow) of the gallbladder. The body and fundal portion (white arrows) of the gallbladder are not enhanced. These findings were the same at 4 hours after injection (not shown). (c) Hepatobiliary scintigraphic image in the anterior projection obtained at 60 minutes after injection of IDA demonstrates visualization of the neck portion (white arrow) of the gallbladder, the extrahepatic duct (open), and the small bowel (black arrow). The body and fundal portion of the gallbladder cannot be visualized.
