Currently, standard segmented cardiac cine and delayed enhancement images are acquired with independent sequences requiring multiple breath-holds (BH), ideal inversion time (TI) setting, and individual image analysis. We describe our initial experience with the use of a multi-contrast real-time cine (multi-TI cine) prototype sequence .
Despite currently having inferior spatial and temporal resolution as compared to standard cine and LGE sequences, multi-TI cine seems to be able to detect myocardial tissue and functional abnormalities, with the advantage of shorter acquisition times, ideal myocardial nulling and combined functional and LGE assessment. Future developments and studies will be needed to adequately determine its accuracy and validate its clinical application.
