Ambulatory cardiac single-photon emission computed tomography stress testing for the evaluation of coronary artery disease at the primary care physician's office is increasingly utilized without data supporting its safety. In this 2-year prospective pilot study of 1266 consecutive stress-myocardial perfusion imaging studies done in the primary care(More)
PURPOSE We demonstrate an improved segmented inversion-recovery sequence that suppresses ghost artifacts arising from tissues with long T1 ( > 1.5 s). THEORY AND METHODS Long T1 species such as pericardial fluid can create bright ghost artifacts in segmented, inversion-recovery MRI because of oscillations in longitudinal magnetization between segments.

Background Bright ghosting due to long-T1 species (e.g. cerebrospinal fluid, pericardial or pleural effusion, fig. 1) often hampers the identification of infarcted myocardium on delayed enhancement CMR. The artifacts are caused by signal oscillations of the long-T1 species due to the periodic application of IR pulses. Previous methods use a dummy heartbeat(More)
