T1ρ-mapping shows promising results for the endogenous detection of myocardial fibrosis. A T1ρ-map can be obtained by multiple T1ρ-weighted images with different spin-lock (SL) preparation times. We propose a cardiac T1ρ-mapping method in a single breath-hold. Five healthy volunteers and 2 patients with chronic myocardial infarction were scanned. T1ρ-mapping was performed by acquiring 5 images with different SL preparation times (SL = 0, 10, 20, 30, 40 ms). High resolution T1ρ-maps were successfully acquired in all subjects. The mean T1ρ-relaxation time was 52.73 ms. Coefficient of repeatability in the healthy subjects was 3.74 ms, and in infarct patients 4.59 ms.
