Reproducibility of circumferential strain on cine displacement encoding with stimulated echoes magnetic resonance imaging before and after contrast at 3T.

ABSTRACT:

Background

Magnetic resonance imaging (MRI) with displacement encoding with stimulated echoes (DENSE) is well recognized for accurate and precise quantification of myocardial displacement and strain, but its reproducibility before and after contrast injection has not been investigated. Gadolinium is the most widely used contrast agent. Ferumoxytol is increasingly used off-label in specific patient groups. We aim to assess the reproducibility of cine DENSE MRI to measure global and segmental circumferential myocardial strain (E_CC) before and after contrast injection for gadolinium and ferumoxytol, respectively.

Methods

All imaging was conducted using 3T scanners. In 11 patients with cardiac disease, breath-hold two-dimensional cine DENSE was acquired in a mid-ventr
