Computer-aided diagnosis (CAD) is a field of medical imaging technology that utilizes computer algorithms and artificial intelligence to assist radiologists and physicians in interpreting medical images, such as X-rays, MRIs, and CT scans. CAD systems can analyze medical images to highlight areas of concern, provide diagnostic suggestions, and improve the accuracy and efficiency of diagnosis. These systems can help healthcare professionals detect early signs of diseases, such as cancer and cardiovascular conditions, leading to earlier treatment and improved patient outcomes. CAD is considered a valuable tool in modern medicine for its ability to enhance diagnostic accuracy and reduce the likelihood of human error.
