This review summarizes the basic principles, technical considerations, and emerging clinical applications of stress T1 mapping for interrogating the myocardial microvascular compartment.
Stress T1 mapping remains investigational for microvascular assessment; leaves open prospective validation before clinical adoption.
In vivo mapping of the myocardial T1 relaxation time has recently attained wide clinical validation of its potential utility. In this review, we address the basic principles of the T1 mapping techniques, with particular attention to the emerging application of vasodilatory stress agents to interrogate the myocardial microvascular compartment, and differences between commonly used T1 mapping methods when applied in clinical practice.
