Cardiac MRI T₂ mapping with heart phase acquisition and improved motion-sensitized driven equilibrium blood suppression.

ABSTRACT:

Background

Cardiovascular magnetic resonance (CMR) imaging relies on T₂ mapping to assess myocardial tissue properties. However, T₂ maps are subject to motion artifacts and signal interference, prompting exploration of techniques such as gradient-spin-echo (GraSE) sequences, heart phase acquisition, and dark blood (DB) imaging to improve image quality and reliability.

Purpose

This prospective study evaluates the T₂ relaxation time (T₂) variability and the image quality of T₂ maps obtained in end-systole and end-diastole with and without fat saturation (FS), using GraSE sequence in CMR imaging. Furthermore, improved motion-sensitized driven-equilibrium (iMSDE) was compared with double inversion recovery (DIR) as an altern
