MR-Guided Cholecystostomy in Pigs
The MR experiment is highly sensitive to materials characterized by long T2 relaxation times. Bile fluid is such a material. Bile-filled structures can hence be displayed on heavily T2-weighted MR sequences without the use of any contrast medium. Use of very long repetition (TR) and echo times (TE) results in a selective display of the biliary system referred to as MR cholangiography (Kaufmann et al. 1989; Schuster et al. 1995). The MR images are acquired non-invasively in any desired plane, providing a truly three-dimensional perspective of the biliary tree, including any pathologic findings (Kaufmann et al. 1989; Schuster et al. 1995).
