Fast myocardial T₁ mapping using shortened inversion recovery based schemes.

ABSTRACT:

Background

Myocardial T₁ mapping shows promise for assessment of cardiomyopathies. Most myocardial T₁ mapping techniques, such as modified Look-Locker inversion recovery (MOLLI), generate one T₁ map per breath-held acquisition (9-17 heartbeats), which prolongs multislice protocols and may be unsuitable for patients with breath-holding difficulties.

Purpose

To develop and characterize novel shortened inversion recovery based T₁ mapping schemes of 2-5 heartbeats.

Study type

Prospective.

Population/phantom

Numerical simulations, agarose/NiCl₂ phantom, 16 healthy volunteers, and 24 patients.

Field strength/sequence

1.5T/MOLLI.

Assessment

All shortened T₁ mapping schemes were characteriz
