Abstract

Purpose: To develop reliable three‐dimensional (3D) segmented echo planar imaging (seg‐EPI) proton resonance frequency (PRF) temperature monitoring in the presence of respiration‐induced B 0 variation. Methods: A free induction decay (FID) phase navigator was inserted into a 3D seg‐EPI sequence before and after EPI readout to monitor B 0 field variations. Using the field change estimates, the phase of each k‐space line was adjusted to remove the additional phase from the respiratory induced off‐resonance. This correction technique was evaluated while heating with MR‐guided focused ultrasound (MRgFUS) in phantoms with simulated breathing and during nonheating conditions in healthy in vivo breasts. Results: With k‐space phase correction, the standard deviation of magnitude images and PRF temperature measurements in breast from five volunteers improved by an average factor of 1.5 and 2.1, respectively. Improved accuracy of temperature estimates was observed after correction while heating with MRgFUS in phantoms. Conclusion: Phase correction based on two FID navigators placed before and after the echo train provides promising results for implementing 3D monitoring of thermal therapy treatments in the presence of field variations due to respiration.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
