Retrospective temporal resolution interpolation alters myocardial strain quantification on compressed sensing cine CMR.

ABSTRACT: Compressed sensing (CS) is a rapidly developing technique that can acquire functional cines of the heart within seconds while free-breathing and it is ideal for assessing cardiac function in non-typical conditions such as when patients are sedated or anaesthetized or undergoing stress exams. CS cines can further include retrospective temporal resolution interpolation (INTP_TR) to improve the frame count per heartbeat, and the impact of INTP_TR on biventricular functional measurements is unknown. We investigated the impact of INTP_TR on left and right ventricular volumetry and strain measurements of CS cines. Nineteen patients with 51 different CS acquisitions were prospectively enrolled. CS cines were acquired at rest, under adenosine stress, oxygen inhalation
