UNLABELLED We have developed a completely automatic algorithm to quantitatively measure left ventricular ejection fraction (LVEF) from gated 99mTc-sestamibi myocardial perfusion SPECT images. METHODS The algorithm operates in the three-dimensional space and uses gated short-axis image volumes. It segments the left ventricle (LV), estimates and displays endocardial and epicardial surfaces for ...
INTRODUCTION Myocardial perfusion magnetic resonance imaging is emerging as a useful modality to assess myocardial ischemia, although there remain challenges related to artifacts, coverage, and quantitation. Recently a rapid undersampled radial k-space perfusion sequence was shown to have promise for qualitative perfusion imaging and offers reduced artifacts and increased coverage compared to m...
