MR thermometry in the human prostate gland at 3.0T for transurethral ultrasound therapy
Elizabeth Ramsay,Charles Mougenot,Max O. Köhler,Michael Bronskill,Michael Bronskill,Laurence Klotz,Masoom A. Haider,Rajiv Chopra,Rajiv Chopra,Rajiv Chopra +9 more
TL;DR: To investigate the spatial, temporal, and temperature resolution of a segmented gradient echo echo‐planar imaging 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 magnetic resonance imaging (MRI)‐controlled transurethral ultrasound thermal therapy.
Temperature-dependent MR signals in cortical bone: Potential for monitoring temperature changes during high-intensity focused ultrasound treatment in bone
Elizabeth Ramsay,Charles Mougenot,Mohammad Kazem,Theodore W. Laetsch,Theodore W. Laetsch,Rajiv Chopra,Rajiv Chopra,Rajiv Chopra +7 more
TL;DR: The potential to monitor temperature changes in cortical bone using a short TE gradient echo sequence is evaluated and high‐intensity focused ultrasound exposures in bone are monitored using temperatures changes in adjacent soft tissues.
Comparison of biphasic and reordered fat suppression for dynamic breast MRI.
TL;DR: To optimize a reordered k‐space acquisition that applies intermittent fat saturation (FS) pulses to allow for a time‐efficient reduction of fat signal in breast MR images, and compare it with an elliptic‐centric biphasic FS method in terms of the degree of fat suppression and speed.
