How to detect aortic dissection on ct scan using deep learning?5 answersDeep learning algorithms have been developed to detect aortic dissection on CT scans. These algorithms use contrast-enhanced CT images for segmentation and detection of aortic dissection. One approach involves using a U-Net based semantic segmentation architecture to segment the aortic true lumen, followed by aortic circularity analysis to obtain slice-level detection results. Another approach uses a 3D convolutional neural network (CNN) to divide the 3D volume into anatomical portions, and then applies 2D CNNs based on pyramid scene parsing network (PSPnet) to segment each specific portion separately. These deep learning algorithms have shown promising results, with high accuracy, sensitivity, and specificity in detecting aortic dissection. They have the potential to support clinical practice by reducing missed diagnoses and providing valuable assistance in selecting treatment options.
