Abstract

Multiparametric choice is needed in Magnetic Resonance Imaging (MRI). In addition to matrix definition, section thickness, accumulation number, the repetition time TR, the echo time TE (for the spin echo technique) and the plane selection are of great importance. In pelvic examination, information supplied by T1 and by T2 weighted images is complementary. So, comparison between the three dimensional sections is of great interest. Although long acquisition times could, in theory, provide better images and therefore more clinical information, the patient comfort must be considered in choosing a reasonable examination time. We believe that it is possible, without great loss of information, not to make inversion recovery sequences. Using a 0.5 T superconducting magnet, sequences were done with TR of 1,200 ms for T2 weighted images and two echoes with TE of 40 or 50 ms. Twice repeated sequences (for averaging purpose) and 256(2) matrix (with a 42 cm field diameter) seem to be well adapted to MRI clinical applications.
