摘要:
A method and apparatus are disclosed for achieving suppression of blood pool signal to detect myocardial infarction using MR technology. After administering a contrast agent into the blood stream of a patient, an RF pulse sequence is applied that includes a slice-selective inversion pulse to suppress normal myocardial tissue followed by a notched inversion RF pulse designed to suppress blood pool in and around the region-of-interest. MR data is then acquired within the region-of-interest that not only has signals from normal myocardial tissue suppressed, but also has blood pool signal suppression to improve delineation of infarcted myocardium from the ventricular blood pool and normal myocardium.
