摘要

心室收缩力的评估是帮助医生选择适当治疗在收缩力水平上发生的心功能异常的重要因素,如运动不足、运动障碍和运动不足。应用协方差分析跟踪心室收缩力是本研究的目的。我们对44例收缩性异常患者和6例收缩性正常患者的放射性核素脑室造影图像进行了检验。本研究的实验结果表明,该方法对心室功能的评价具有良好的再现性(准确度=0.94,灵敏度=0.94,特异性= 1,AUC =0.97)。

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).
