An Overview of Advanced Mammographic Techniques
Mammography describes a distinct type of imaging which utilizes low-dose X-ray system for examination of breasts. Therefore, a mammogram or a mammography exam facilitates early diagnosis or detection of breast diseases. Moreover, mammograms are utilized as the screening tool for early detection of breast cancer amongst women that do not experience the symptoms. Additionally, mammograms are also used for detection and diagnosis of breast diseases in women who experience the symptoms like pain, nipple discharge or a lump.
Mammography diagnostic techniques include computer-aided detection, digital mammography, screening mammography and diagnostic mammography. These techniques utilize different methodologies and devices for examination of breast abnormalities.
Digital mammography features a mammography system that utilizes solid-state detectors for conversion of X-rays into electrical signals. These signals produce the images of breasts which could be seen on a computer’s screen.
Computer-aided detection (CAD) system is another advanced technique that utilizes a digitized mammographic image which can be obtained using a digitally acquired mammogram or a film mammogram. In this technique, the computer software finds out the abnormal areas of mass, calcification or density which might indicate presence of breast cancer. Thereafter, the CAD system highlights the abnormal areas in the images.
Diagnostic mammography is utilized for evaluation of a patient with an abnormal clinical finding like breast lumps which are identified by a doctor during physical examination or during self-examination by the woman. The technique might also be utilized after a patient has undergone an abnormal screening mammography. This facilitates the evaluation of the abnormal area during the screening examination.
Mammography diagnostic techniques are extremely useful for early-stage detection of breast diseases.
