Abdominal MR Imaging at 3.0T: Preliminary Clinical Experience with 2-Point mDIXON as an Alternative to eThrive and Chemical Shift Imaging

Purpose: To assess a new water suppressed T1-weighted imaging method, 2-Point multi-echo DIXON, in the abdomen at 3T. Materials and Methods: Breath held 3D axial 2-Point multi-echo fast field echo (FFE) DIXON (mDIXON) imaging was performed using a 3T MR system (Philips Healthcare) with typical imaging parameters of TR 4.2/TE1 1.5/TE2 2.8ms (shortest TE values rather than out-of-phase and in-phase values were used, a unique benefit of mDIXON), in-plane resolution of 1.3×1.3mm, and acquired/reconstructed slice thickness of 2.6/1.3mm. Acquisition times were limited to 22 seconds or less to minimize breath hold time…
