Useful Improvements in Mammography Techniques

Mammography refers to a specific kind of imaging techniques that utilizes low-dose X-ray system for examination of breasts. A mammogram or mammography examination is utilized for facilitating early detection as well as diagnosis of breast abnormalities in women. Recently, there have been two improvements in the area of mammography. These include computer-aided detection (CAD) and digital mammography. Let us examine the utilization of CAD in mammography and breast imaging.

The use of CAD for mammography is a new improvement in the area of breast imaging. Primarily, CAD technology acts as second pair of eyes because it reviews the mammogram film of a patient after a radiologist has previously examined it. This implies that the film is reviewed after an initial analysis. In case, the computer software identifies any kind of breast abnormality/regions of interest on mammogram film, they are marked. Therefore, the radiologists can once again examine the mammogram film for determining if the marked regions are suspicious and need to be re-examined.

Depending upon the requirement, biopsy or other imaging tests are conducted. However, CAD technology also enables a radiologist to make final interpretation of mammograms. The application of CAD for mammography involves the usage of digitized mammographic image. This image could either be obtained through a digitally acquired mammogram or a traditional film mammogram. Next, the computer software finds out the areas of abnormal mass, density or calcification. This might be an indicator of cancerous growth. The abnormal areas are highlighted in the images which gives an indication for additional analysis.
