The conventional Dual Inversion Recovery T2-weighted Black Blood (c-DIR-BB) on myocardial MRI is useful for the clinical diagnosis. One of the problems of c-DIR-BB is aliasing artifact, resulting in degradation of image quality. The zoomed method for improved aliasing artifact, orthogonal selection (i.e. phase / slice direction) excites to suppress tissue signals outside with a smaller FOV in phase encoding direction. Hence the DIR-BB using zoomed methods was improved image quality by orthogonal select excitation RF pulse.
