Native T Mapping in the Diagnosis of Cardiac Allograft Rejection: A Prospective Histologically Validated Study.

Objectives: This study aimed to determine the role of T mapping in identifying cardiac allograft rejection.

Background: Endomyocardial biopsy (EMBx), the current gold standard to diagnose cardiac allograft rejection, is associated with potentially serious complications. Cardiac magnetic resonance (CMR)-based T mapping detects interstitial edema and fibrosis, which are important markers of acute and chronic rejection.
