3D MRI thermometry of MR-induced heating of a wire and determination of total generated heat
Introduction: Conductive implants are in most cases a strict contraindication for MRI examinations. Applied RF pulse power during the MRI measurement can lead to severe heating of the surrounding tissue. The use of fiberoptic probes is the standard procedure for monitoring these heating effects. However, the observed temperature increase is highly dependent on the positioning of such a probe as...
متن کاملReal Time Measurement of Heating Near Metallic Implants Throughout a Phantom Using Phase-Shift MR Thermometry
H. Bassen, A. Kam, W. Kainz, G. Mendoza, H. Wang Center for Devices and Radiological Health, Food and Drug Administration, Rockville, MD, United States, Diagnostic Radiology Department, National Institutes of Health, Bethesda, MD, United States Introduction – Potentially dangerous heating occurs at the narrow tip of certain medical implants in patients being imaged by standard MRI systems [1, 2...
متن کاملSSFP-based MR thermometry.
Of the various techniques employed to quantify temperature changes by MR, proton resonance frequency (PRF) shift-based phase-difference imaging (PDI) is the most accurate and widely used. However, PDI is associated with various artifacts. Motivated by these limitations, we developed a new method to monitor temperature changes by MRI using the balanced steady-state free precession (balanced-SSFP...
متن کاملSpiral-based 3D MR thermometry
Background/introduction Real time MR thermometry, usually based on the protonresonance frequency shift, is a key aspect of MR-guided focused ultrasound procedures. The desire to monitor the entire sonicated volume has led the field towards the development of rapid, 3D methods; however, acquiring fully sampled 3D volumetric data to monitor heating is time consuming, and so fast methods must be d...
متن کاملRadiofrequency energy-induced heating during MR procedures: a review.
During an MR procedure, most of the transmitted RF power is transformed into heat within the patient's tissue as a result of resistive losses. Not surprisingly, the primary bioeffects associated with the RF radiation used for MR procedures are directly related to the thermogenic qualities of this electromagnetic field. This review article discusses the characteristics of RF energy-induced heati...
