Although T2-weighted (T2W) MRI has a good tumor contrast, it is not a good choice for defining the applicator because of signal dropout and geometric distortion around the titanium applicator. In this study, we evaluated the possibility of using proton density weighted (PDW) MRI to improve ...

PurposeCompressed sensing (CS) is a method to accelerate MRI acquisition by acquiring less data through undersampling of k-space. In this prospective study we aimed to evaluate whether a three-dimensional (3D) isotropic proton density-weighted fat saturated sequence (PDwFS) with CS can replace co...

This might be due to the high spin density of MS lesions, thus distinguishing them from the surrounding brain tissue. For this reason, double-echo T2-weighted sequences at 3T are recommended to improve the detectability of MS lesions. 展开 关键词: FLAIR Proton density 3T Multiple sclerosis ...
To develop and evaluate a framework for simulating low-field proton-density weighted MRI acquisitions based on high-field acquisitions, which could be used to predict the minimum B0field strength requirements for MRI techniques. This framework would be particularly useful in the evaluation of de-noisi...
