Detecting Abnormal ventricular Contractility from Radionuclide Ventriculography Images

The evaluation of ventricular contractility is an important factor helping doctors in choosing the appropriate therapy for abnormal heart functioning occurring at the level of contractilities such as hypokinesia, diskinesia, and akinesia. Applying covariance analysis to track the ventricular contractility is the purpose of this study. We examined the proposed method on radionuclide ventriculography images corresponding to 44 patients with abnormal contractility and 6 with normal contractility. The Experimental results of this study show that the proposed method has a good reproducibility in the assessment of the ventricular function (accuracy=0.94, sensitivity=0.94,specificity= 1 and AUC =0.97).
