Journal ArticleDOI
Ex vivo tissue-type independence in proton-resonance frequency shift MR thermometry
TL;DR: A method of calibrating the temperature dependence of the proton‐resonance frequency is described and results are presented that indicate a tissue‐type independence, including physiological perturbations and volume magnetic susceptibility effects from geometry and orientation.
Journal ArticleDOI
Quantifying tissue damage due to focused ultrasound heating observed by MRI.
Simon J. Graham,L. Chen,M. Leitch,R. D. Peters,Michael Bronskill,F.S. Foster,R. M. Henkelman,Donald B. Plewes +7 more
TL;DR: The results suggest that quantitative MR guidance of thermal coagulation therapy is feasible, and they provide information useful for designing future investigations in vivo.
Journal ArticleDOI
Prostate cancer: MR imaging and thermometry during microwave thermal ablation-initial experience.
Jianan Chen,J. A. Moriarty,Derbyshire Ja,R. D. Peters,John Trachtenberg,Bell Sd,James Doyle,Arrelano R,Graham A. Wright,R. M. Henkelman,R S Hinks,Lok Sy,Toi A,W Kucharczyk +13 more
TL;DR: Percutaneous interstitial microwave thermoablation of locally recurrent prostate carcinoma was continually guided with magnetic resonance (MR) imaging to derive tissue temperature change on the basis of proton-resonance shift.
Journal ArticleDOI
Magnetic resonance thermometry for predicting thermal damage: an application of interstitial laser coagulation in an in vivo canine prostate model.

TL;DR: Histological evaluation shows that the thermal‐injury boundary can be predicted from a threshold‐maximum temperature or an equivalent Arrhenius t43 period of 200 minutes, but it is not reliably predicted using the temperature‐time product.
Journal ArticleDOI
Proton-resonance frequency shift MR thermometry Is affected by changes in the electrical conductivity of tissue
R. D. Peters,R. M. rk Henkelman +1 more
TL;DR: A potential source of variation in the PRF‐shift method of thermometry is identified that manifests as a constant incremental phase shift per unit change in temperature that is independent of the echo‐time setting, when constructing temperature‐sensitive phase images from a gradient‐echo pulse sequence.
