Computer-Aided Detection (CAD)

Computer-Aided Detection (CAD) systems assist radiologists by analyzing mammogram images and highlighting potential areas of concern. CAD helps identify patterns in the breast tissue that might indicate the presence of a tumor or abnormality. By flagging suspicious areas, CAD systems improve the accuracy of interpretations and increase the chances of early detection. While CAD systems do not replace human expertise, they serve as valuable tools to assist healthcare professionals in making accurate diagnoses.

Applications of Mammography Equipment

Screening Mammography

Screening mammography is the most common use of mammography equipment. It is typically performed on asymptomatic women as part of a routine breast cancer screening program. The goal of screening mammography is to detect cancer early, before it becomes symptomatic, increasing the chances of successful treatment. In many cases, screening mammograms are conducted annually or biennially for women over the age of 40 or 50, depending on their risk factors and healthcare guidelines.

Diagnostic Mammography

Diagnostic mammography is performed when a patient has symptoms, such as a lump or abnormal discharge, or when a screening mammogram shows unusual findings. Diagnostic mammography is more detailed than screening mammography and focuses on a specific area of concern. It can help confirm whether an abnormality is benign or malignant and guide further diagnostic procedures, such as biopsies or ultrasounds.

Pre-Surgical Planning

Mammography plays an essential role in pre-surgical planning for patients with diagnosed breast cancer. By providing detailed images of the tumor’s size, shape, and location, mammography helps surgeons plan the most effective approach for removing the tumor. Accurate pre-surgical imaging ensures that the surgeon can remove the tumor while minimizing damage to surrounding healthy tissue, ultimately improving the patient’s prognosis.

Monitoring Treatment Response

Mammography is not only useful for diagnosing breast cancer but also for monitoring the effectiveness of treatments such as chemotherapy and radiation therapy. Regular mammograms allow healthcare providers to track the response of the tumor to treatment, adjusting the therapy as necessary. Post-treatment mammograms can also be used to check for any recurrence of the cancer.
