Very fast cardiac imaging.
With very fast MR imaging techniques, myocardial perfusion can be assessed by monitoring the changes of myocardial signal intensity over time following bolus injection of a contrast medium. Very fast MR imaging techniques also allow for freezing of cardiac motion that is important for coronary MR angiography and their high temporal resolution allow for coronary flow reserve measurements. In the current overview, basic principles and strategies of very fast cardiac MR imaging are presented. In the second part, applications of these fast sequences in the fields of myocardial perfusion, coronary MR angiography, and low measurements are presented.
