New approach based on the combination of phase and orientation vector for the detection of wall motion abnormalities

Résumé

Objective: The aim of this study is to propose a new approach based on the combination of local phase and orientation vector for the regional detection of cardiac wall motion. Materials and Methods : Cine-MRI images obtained in 20 patients were used to compute the proposed image. Two expert radiologists reviewed the cine-MRI images to define regional wall motion areas for each patient. Results : According to the results. The accuracy of the detection of wall motion abnormalities improved by adding the proposed images (from 79.5% to 86.4%) together with sensitivity (from 79.4 % to 87.3%) and specificity (from 74.3 % to 86.4%). Conclusion: The use of the proposed image based on local phase and orientation vector proved to be a promising technique for the detection of left ventricular wall motion abnormalities.
