Abstract:A ferumoxytol-enhanced MRA technique using Ultrashort Time-to-Echo (UTE) sequences is demonstrated for kidney vasculature mapping and renal mass assessment. The blood volume (BV) map is calculated by scaling the post- and pre-contrast subtraction image from 0 to 1. BV is measured in one cystic mass (-6±7)% and one complex mass (17±8)% with sub-regions BV up to (32±10)% and (30±7)%. The quantification of BV provides a measurement of the distribution of micro-vessel de… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
