FASt single-breathhold 2D multislice myocardial T₁ mapping (FAST1) at 1.5T for full left ventricular coverage in three breathholds.

ABSTRACT:

Background

Conventional myocardial T₁ mapping techniques such as modified Look-Locker inversion recovery (MOLLI) generate one T₁ map per breathhold. T₁ mapping with full left ventricular coverage may be desirable when spatial T₁ variations are expected. This would require multiple breathholds, increasing patient discomfort and prolonging scan time.

Purpose

To develop and characterize a novel FASt single-breathhold 2D multislice myocardial T₁ mapping (FAST1) technique for full left ventricular coverage.

Study type

Prospective.

Population/phantom

Numerical simulation, agarose/NiCl₂ phantom, 9 healthy volunteers, and 17 patients.

Field strength/sequence

1.5T/FAST1.

Assessment

Two FAST1
