Abstract
A relaxation labelling model was implemented to detect 3-d endo- and epicardial surfaces in ECG gated single photon emission computed tomographic perfusion studies of the heart. The model was tested using studies from normal volunteers and from patients with coronary artery disease. LV volumes calculated from the abnormal patient studies correlated well with those from contrast ventriculography, r=0.82 and r=0.89 for end systole and end diastole, respectively. The ejection fractions correlated well with those from radionuclide ventriculograms (r=0.93.) For normal volunteers, left ventricular endocardial volumes calculated using relaxation labelling correlated to those computed from user-traced surfaces with r-0.98. The correlation between epicardial volumes computed using relaxation labelling and hand-traced edges was also 0.98.
