The purpose of this study was to assess the value of fast-spin-echo (FSE) sequences without and with fat suppression as well as gradient-and-spin-echo (GRASE) sequences for the detection and subsequent characterization of focal liver lesions. A total of 51 consecutive patients with clinically suspected focal liver lesions were studied. ⋯ Fat suppression did not improve the performance of FSE. GRASE sequences with multiple excitations were clinically superior to the faster single-shot approach.

To determine the efficacy of fast MRI techniques using a tailored imaging design (breathhold and array-surface coil), conventional T1-, T2-weighted spin-echo (SE) sequences and breathhold gradient-echo (GRE) T1- and breathhold fast SE T2-weighted images were compared. ⋯ The fast MRI techniques demonstrated a superiority to conventional imaging regarding image quality and presence of artifacts. Therefore, fast imaging techniques can replace conventional techniques, at least in patients that can sufficiently sustain breathing.
