Dynamic Contrast-Enhanced Breast MRI using Flexible Radial Undersampling with Compressed Sensing Reconstruction

Introduction: Flexible radial imaging allows multiple image sets, each having a different spatiotemporal balance, to be retrospectively reconstructed from the same dataset [1,2]. One of the applications that may benefit from this flexibility is dynamic contrast-enhanced breast imaging, in which the optimal spatiotemporal balance for image diagnosis is unknown. Images from radial undersampling h...

Analysis of Dynamic Contrast Enhanced MRI Datasets

The purpose of this research is to perform automated analysis of 4D dynamic contrast enhanced MRI datasets (DCE-MRI) of the hand and wrist relating to rheumatoid arthritis (RA) studies. In DCE-MRI, sequences of images are acquired from the joints over time, during which a contrast agent pre-injected into a patient enhances disease affected tissues. Measurement of this enhancement, which is spec...

Dynamic contrast - enhanced MRI in cancer REVIEW

Dynamic contrast-enhanced MRI has been proven to be a valuable technique in cancer imaging. The poorly formed and leaky vessels formed during angiogenesis to supply tumors facilitate an increased uptake of intravenously administered contrast agents in comparison to normal vasculature. The use of mathematical modeling techniques on the change in tumor signal intensity as a function of time provi...
