Impact of Temporal Resolution and Methods for Correction on Cardiac Magnetic Resonance Perfusion Quantification.

ABSTRACT:

Background

Acquisition of magnetic resonance first-pass perfusion images is synchronized to the patient's heart rate (HR) and governs the temporal resolution. This is inherently linked to the process of myocardial blood flow (MBF) quantification and impacts MBF accuracy but to an unclear extent.

Purpose

To assess the impact of temporal resolution on quantitative perfusion and compare approaches for accounting for its variability.

Study type

Prospective phantom and retrospective clinical study.

Population and phantom

Simulations, a cardiac perfusion phantom, and 30 patients with (16, 53%) or without (14, 47%) coronary artery disease.

Field strength/sequence

3.0 T/2D saturation recovery spoiled gradient echo sequence.

Assessment

Dynamic perfusion da
