MR Thermometry in the Human Prostate Gland at 3.0T for Transurethral Ultrasound Therapy

摘要

PurposeTo investigate the spatial, temporal and temperature resolution of a segmented gradient echo echo-planar imaging (EPI) technique as applied to proton resonance frequency (PRF) shift thermometry at 3 T in the human prostate gland, and to determine appropriate sequence parameters for MRI-controlled transurethral ultrasound thermal therapy.
