Persistent bile leak after liver transplantation: biloma drainage and endoscopic retrograde cholangiopancreatographic sphincterotomy.

abstract：:The normal anatomy of the larynx and base of the tongue as seen on nuclear magnetic resonance (NMR) images was studied. Scans of normal volunteers were obtained using a 3.5 kilogauss (0.35 T) superconductive magnet and a 3.0 kilogauss (0.3 T) permanent magnet. The NMR images were compared with images obtained by CT an...

abstract：:The authors describe an adaptive motion correction method for three-dimensional magnetic resonance (MR) imaging. Three-dimensional imaging offers many advantages over two-dimensional multisection imaging but is susceptible to image corruption due to motion. Thus, it has been of limited use in the imaging of mobile str...
