　View Summary

[Purpose]To evaluate the artifact reduction around implanted metal devices using MAVRIC-SL (multi-acquisition variable-resonance image combination selective). [Mate and Metho]
The subjects were three metal hip implant devices (Titanium (Stryker), cobalt-chromium (Stryker) and stainless-steal (BIOMET) stem hip modules). Each device was fixed to the plastic container with the grid plate, and filled with Vinyl acetate. Each phantom was scanned using 3.0T MRI scanner (SIGNA Pioneer: GE) with TDI Anterior Array coil. Conventional Fast Spin Echo (FSE) and MAVRIC-SL were scanned with the following parameters: FSE-XL (MAVRIC-SL) TR/TE/ETL=500/5.6msec/2 (500msec/6.8msec/8), FOV=30cm, Slice Thickness=5mm, NEX=1 (0.5). Three radiologists were visually evaluated the severity of metal artifact with 5-point scale.
[Results]
Image distortion was reduced with MAVRIC-SL for all three devices we tested, in comparing to FSE. Stainless-steal caused largest artifacts for both FSE and MAVRIC-SL sequence, followed by Titanium and cobalt-chromium device. Our results suggested that MAVRIC-SL might be useful for detecting tumor and/or inflammation around the metallic implant in the clinical setting.
