METHOD, DEVICE AND COMPUTER-READABLE MEDIUM FOR AUTOMATICALLY DETECTING A HAEMODYNAMICALLY SIGNIFICANT CORONARY STENOSIS

摘要

The invention relates to a computer-implemented method for determining the presence of a coronary stenosis for a patient, comprising a step of receiving at least one curvilinear or stretched multiplanar tomodensitometry (X-ray scan) medical image of said patient including the coronary stenosis, and also a step of detecting said coronary stenosis on said image or on a portion of said image by using a first deep neuronal network. The invention is characterized in that it also comprises a step of predicting a coronary fractional flow reserve (FFR) value range by using a second trained deep neuronal network, applied directly to the images or portions of images detected, and/or by manual, semi-automated and/or automated measurement of at least two morphological criteria chosen from the minimum diameter of the stenosis, the minimum surface area of the stenosis, the maximum degree of coronary stenosis in terms of diameter, the maximum degree of coronary stenosis in terms of surface area, the length of the stenosis and/or the myocardial mass or the myocardial mass and the percentage of myocardial mass downstream of the coronary stenosis.
