Fast frequency mapping with balanced SSFP: theory and application to proton-resonance frequency shift thermometry.
A method is presented for the rapid acquisition of frequency maps based on multiecho balanced steady-state free precession (balanced SSFP, fast imaging with steady precession (True FISP), fast imaging employing steady-state excitation (FIESTA), or balanced fast field echo (FFE)). This technique was applied to measure temperature changes within a gel phantom based on the temperature-sensitive wa...
متن کاملProton-resonance frequency shift MR thermometry is affected by changes in the electrical conductivity of tissue.
The proton-resonance frequency (PRF) shift method of MR thermometry provides an easy and practical means of quantitatively monitoring in vivo temperatures for MR image-guided thermal-coagulation therapy. However, reported discrepancies in the numerical value of the PRF-thermal coefficient persist, when measured in a variety of experimental conditions and in different tissue types, both ex vivo ...
متن کاملVolumetric thermometry with proton resonance
Proton resonance frequency (PRF), by which it precesses in the magnetic field, alters due to change in temperature, which can be detected with magnetic resonance imaging (MRI). MRI scanner uses protons’ nuclear magnetic resonance phenomenon. The target is first excited with a radio frequency pulse, then it’s relaxation to initial stage is observed. Parts with different temperatures can be mappe...
متن کاملMRI thermometry in phantoms by use of the proton resonance frequency shift method: application to interstitial laser thermotherapy.
In this work the temperature dependence of the proton resonance frequency was assessed in agarose gel with a high melting temperature (95 degrees C) and in porcine liver in vitro at temperatures relevant to thermotherapy (25-80 degrees C). Furthermore, an optically tissue-like agarose gel phantom was developed and evaluated for use in MRI. The phantom was used to visualize temperature distribut...
متن کاملAccurate and Efficient Mapping of Flip Angle and T1 using Simultaneous Actual Flip Angle - Variable Flip Angle Imaging (AFI-T1)
Introduction: The knowledge of flip angle values is essential for accurate modeling in many quantitative MRI techniques. Recently, Actual Flip Angle Imaging (AFI) was proposed to account for multiple sources of flip angle variations such as transmit field inhomogeneity, B0 variations, slab profile, and excitation pulse effects [1]. AFI was successfully applied to yield system-independent T1 rel...
