In bright blood imaging, partial volume averaging of small moving intracavitary structures and surrounding bright blood often degrades the depiction of such morphology. Therefore, structures including papillary muscles, trabeculations, and intracardiac masses are better visualized with dark blood (DB) techniques. DB imaging also provides better image contrast for low signal structures since it avoids the dynamic range compression present in bright blood imaging. DB sequences are thus the standard imaging tool for assessing cardiac morphology, but they do not contain information about motion, for example of mobile intracardiac masses. We therefore developed a novel dark blood gradient echo cine sequence that simultaneously depicts morphology, motion of intracardiac structures, and cardiac contraction.
The presented DB cine technique reliably suppresses blood signal and thereby improves the depiction of intracardiac structures, masses, papillary muscles and trabeculations. The method is useful for simultaneously assessing cardiac function and morphology, for example in the setting of endocarditis or the presence of mobile masses.
