✦ Synopsis
The application of an edge detection algorithm (EDA) in defining the boundary of the left ventricle (LV) in multiple gated (MG) cardiac studies has been assessed by comparison of the left ventricular ejection fraction (LVEF) derived from X-ray contrast ventriculography (CV) in a series of patients. The results demonstrate good correlation between methods irrespective of the projection and LV status when an EDA is used, such that the correlation in anterior and left anterior oblique (45 degrees) views is 0.91 and 0.86 respectively.
