Improved k-space-based MR thermometry by joint PRF phase shift and T1/T2* attenuation estimation
Background/introduction MR temperature mapping based on the proton resonance frequency (PRF) shift is used in MR-guided focused ultrasound procedures for dosimetry and safety monitoring. While conventional PRF-shift thermometry is based on calculating a phase difference between two reconstructed MR images, Gaur et al [1,2] have recently described two algorithms that estimate temperatureinduced ...
متن کاملHigh magnetic field water and metabolite proton T1 and T2 relaxation in rat brain in vivo.
Comprehensive and quantitative measurements of T1 and T2 relaxation times of water, metabolites, and macromolecules in rat brain under similar experimental conditions at three high magnetic field strengths (4.0 T, 9.4 T, and 11.7 T) are presented. Water relaxation showed a highly significant increase (T1) and decrease (T2) with increasing field strength for all nine analyzed brain structures. S...

متن کاملSegmentation of T1-, T2-, and PD-Weighted MR Images
Multimodal segmentation, like the physicians in practice, uses several images, representing different features of the object under investigation, to make segmentation decisions. In this paper, a multimodal twodimensional segmentation method is introduced. The principle of this method is the combination of multimodal region growing and multimodal edge detection. The combining condition is univer...
متن کاملWhole brain myelin mapping using T1- and T2-weighted MR imaging data
Despite recent advancements in MR imaging, non-invasive mapping of myelin in the brain still remains an open issue. Here we attempted to provide a potential solution. Specifically, we developed a processing workflow based on T1-w and T2-w MR data to generate an optimized myelin enhanced contrast image. The workflow allows whole brain mapping using the T1-w/T2-w technique, which was originally i...
