MR Imaging Near Metal with 3D UTE-MAVRIC Sequences

Michael Carl¹

The potential of using a MAVRIC-like combination of images obtained at different spectral frequencies with UTE sequences rather than FSE sequences for imaging in the presence of metal was investigated. Phantom and in-vivo studies were performed. UTE-MAVRIC sequences were able to significantly reduce typical artifacts near metal implants and detect very short T2 signals not seen with clinical pulse sequences. Thus, UTE-MAVRIC may further improve the diagnostic capability MR near metal implant, by visualizing short T2 tissues such as tendons, ligaments and cortical bone.
