Does cardiovascular magnetic resonance myocardial feature tracking (CMR-FT) reliably detect quantitative wall motion and strain during dobutamine stress?
CMR-FT holds promise for easy and fast quantification of wall mechanics and strain during dobutamine stress, though observer variance needs reduction.
CMR-FT reliably detects quantitative wall motion and strain derived from SSFP cine imaging that corresponds to inotropic stimulation. The current implementation may need improvement to reduce observer-induced variance. Within a given CMR lab; this novel technique holds promise of easy and fast quantification of wall mechanics and strain.
Schuster et al. (2011) studied this question.
