Imaging of the heart has proven to be one of the most challenging applications of MRI technology. MR data acquisition typically takes on the order of seconds to minutes to obtain high resolution images. Irregular cardiac and respiratory motion during this period can give rise to significant artifacts and can render images non-diagnostic. A number of different strategies have evolved to synchronize MR image acquistion with physiological motion. More recently, imaging times have been reduced to under 100msec, fast enough to freeze most physiological motion and permit real-time imaging without cardiac or respiratory synchronization. Strategies for physiological synchronization and real-time MRI will be reviewed in the presentation.
