Abstract
The fast spin-echo pulse sequence allows T2-weighted MR images to be acquired more rapidly than is possible with conventional spin-echo sequences, and phased-array coils can provide a higher signal-to-noise ratio than is possible with the body coil. The combination of these methods permits higher resolution images to be obtained with more signal averages despite shorter imaging times. In this study, initial technical comparisons designed to confirm the advantage of combining fast spin-echo pulse sequences with a pelvic phased-array multicoil were followed by an assessment of the value of these methods for the localization and staging of prostatic carcinoma.Seventy-one men with known (60) or suspected (11) prostatic carcinoma were imaged with T2-weighted fast spin-echo pulse sequences in the axial and coronal planes with a phased array of four surface coils (multicoil) for signal reception. Four of these men also were imaged with fast spin-echo sequences and the body coil, and six of these men also were im...Keywords
