Conference Abstract: Slow infusion dce-mri

Slow infusion improves precision of liver function measurements by DCE-MRI

Sirisha Tadimalla and Steven Sourbron


The British Chapter of ISMRM Annual Meeting, 24-26 September 2018, Somerville College, Oxford

 

Background

Quantitative dynamic contrast-enhanced (DCE) MRI with a rapidly injected bolus of gadoxetate can be used to quantify liver perfusion and transporter function [1,2]. Measuring these rapid changes requires high temporal resolution, and this involves compromises in spatial resolution, coverage or SNR. However, when the aim is to measure hepatocellular function (a slow process), rather than perfusion (a fast process), there is no rationale for a rapid injection.
