Simultaneous Mapping of T₁ and T₂ Using Cardiac Magnetic Resonance Fingerprinting in a Cohort of Healthy Subjects at 1.5T.

ABSTRACT:

Background

Cardiac MR fingerprinting (cMRF) is a novel technique for simultaneous T₁ and T₂ mapping.

Purpose

To compare T₁ /T₂ measurements, repeatability, and map quality between cMRF and standard mapping techniques in healthy subjects.

Study type

Prospective.

Population

In all, 58 subjects (ages 18-60). FIELD STRENGTH/SEQUENCE: cMRF, modified Look-Locker inversion recovery (MOLLI), and T₂ -prepared balanced steady-state free precession (bSSFP) at 1.5T.

Assessment

T₁ /T₂ values were measured in 16 myocardial segments at apical, medial, and basal slice positions. Test-retest and intrareader repeatability were assessed for the medial slice. cMRF and conventional mapping sequences
