Contrast steady state (CSS) may be achieved using continuous contrast infusion following bolus. This technique was used to acquire high resolution late gadolinium enhanced (LGE) scar imaging of 8 pigs with chronic myocardial infarction. CSS imaging allowed extended acquisition to facilitate high-resolution 3D LGE imaging with improved signal-to-noise, contrast-to-noise and overall image quality. CSS may also be used in experimental studies, when total gadolinium bolus is not restricted, to directly compare imaging sequences acquired using consistent contrast distributions.
