In mammography, what does CAD primarily assist with?

The primary function of Computer-Aided Detection (CAD) in mammography is to assist radiologists in identifying potential abnormalities in the breast tissue. CAD systems analyze the mammographic images for signs of breast cancer, including masses and microcalcifications, which may be indicative of malignancy. When the system detects these potential abnormalities, it highlights them for the radiologist’s review, aiming to improve diagnostic accuracy and increase the likelihood of early detection.

This technological aid is particularly valuable because it serves to augment the radiologist's expertise by providing a second pair of "eyes" that can help catch lesions that may be missed during the initial viewing. CAD has been shown to improve the sensitivity of mammography, thereby contributing to better outcomes for patients through earlier diagnosis and intervention.

While reducing radiation exposure, enhancing film quality, and improving patient comfort are important components of mammographic practice, they do not specifically relate to the role of CAD, which is focused predominantly on the detection of abnormalities within the images produced.
