Abstract
The authors evaluated a magnetization preparation scheme with a "notched" s ection profile for T1-weighted first-pass myocardial perfusion magnetic res onance (MR) imaging at 1.5 T. The pulse sequence consisted of a preparation sequence followed by an interleaved gradient-echo echo-planar sequence. Im age contrast was evaluated in a feasibility study in 12 adult patients. The notched saturation pulse allowed long magnetization recovery times without sacrificing section coverage. Image contrast between normal and ischemic m yocardium was excellent.
