MRI of the Gastrointestinal Tract: Coils, Sequences, Techniques extramural tissues. Interpolated 3D T1w breath-hold sequences used with antiperistaltic pharmacologic agents provide for pre- and postintravenous gadolinium imaging that can encompass whole sections of the GI tract. Dynamic imaging is possible by using balanced gradient echo and/or single-shot half

Contrast Media for MRI of the Gastrointestinal Tractption of water and the subsequent “collapse” of the gut, nonabsorbable particles need to be dissolved in the solution. By increasing the osmolarity, the distension of the intestine increases linearly as a consequence of the dose—response relationship that exists between these two parameters. The ora

MRI of the Colon (Colonography): Resultsnography. Current evidence suggests that MR colonography has sufficient accuracy for detecting colorectal cancer and clinical significant polyps. Efforts are made to replace rectal enemas by gaseous distension as in CT colonography, which may improve acceptance of MR colonogra-phy. The wide ranges o
