Abstract

A new method is presentd for the quantitative determination of regional blood volumes in vivo. It is based on rapid quantitative T~1~ mapping by Snapshot FLASH MRI combined with the injection of an intravascular MR contrast agent. Regional blood volumes in four different tissues of the rat (skeletal muscle, heart, liver, kidney) were determined in an In vivo experiment.

## Abstract In the present study we investigated the effects of water exchange between intra‐ and extravascular compartments on absolute quantification of regional myocardial blood flow (rMBF) using a saturation‐recovery sequence with a rather long inversion time (TI, 176 ms) and a __T__~1~‐shorten
