Five quantitative methods are compared for sensitivity and specificity in the diagnosis of regional left ventricular impairment in right-anterior-oblique (RAO) cineangiography. The five methods include center of mass (CMM), long axis method (LAM), Stanford method (SM), area based method (ABM), and normalized curvature difference function (NCDF) method. The CMM and LAM use floating reference systems whereas SM and ABM retain the alignment of end diastolic and end systolic shapes. The NCDF method does not use a reference system. 108 patients consisting of 48 normals and 60 infarcted cases with coronary artery disease are studied. Global specificity (98%) is highest with the ABM. Global sensitivity (97%) and regional sensitivity (95%) is highest with the NCDF method.
