The major aim of this study was to quantitatively investigate LV myocardial HPF-phase in gradient echo images in normal subjects to determine normal ranges as a function of TE and anatomical position and then compare HPF-phase values in patients with myocardial infarction of varying ages with normal ranges. Myocardial high pass filtered myocardial phase is small and normally varies by anatomical myocardial segment. Myocardial hemorrhage causes a significant phase decrease beyond these normal variations. HPF-phase images represent a quantitative, high quality method for the detection of myocardial hemorrhage without the need for the presence or high quality visualization of myocardial edema.
