Abstract
A method and apparatus-are disclosed for achieving suppression of blood pool signal to detect myocardial infarction using MR technology. An RF pulse sequence is applied that includes a notched inversion RF pulse designed to suppress blood pool in and around a 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.
Claims21
A method of MR imaging comprising applying a pulse sequence having a slice-selective inversion RF pulse designed to suppress myocardial tissue followed by a notched inversion RF pulse designed to suppress blood pool at least within a region-of-interest.
An MR pulse sequence comprising a notched inversion RF pulse following a primary slice-selection inversion RF pulse and having a stop-band co-incident with that of the primary slice-selection inversion RF pulse.
AN MRI apparatus comprising a computer programmed to transmit a notched inversion RF pulse with an inversion time selected to invert regions inside and outside a desired imaging slice such that signals from blood flowing into the desired imaging slice are suppressed.
