Use of 3-D Mammography as an Advanced Technique of Breast Imaging

Digital mammography, wherein the detector utilizes digital technology is considered be a better technology than the traditional analog screen-film mammography, particularly for dense breasts which are not convenient for imaging. But the long-term prospect of digital mammography is its possible utilization in the form of an enabler of advanced imaging methods.  Tomosynthesis or 3-D mammography is one such imaging technology that exhibits considerable prospects in increasing the accuracy of mammography.

Breast tomosynthesis is a procedure that involves taking images from various angles around a stationary compressed breast, along with the overall dose of radiation identical to the traditional mammography. Later, the images that are taken are converted into 3-D images in a manner that is identical to MRI or CT images. Moreover, the values of 3-D images in tumors are less possible to be hidden amidst normal tissue as they are in the conventional (2-D) mammogram. Besides this, the clinical trials of 3-D mammography which are conducted during the early years of a woman’s life highlights the possibility of a decrease in the need for further diagnostic imaging and enhanced cancer detection. Consequently, these women are found to be free from cancer.

The three-dimensional mammography could be conducted over a modified digital mammography system wherein the X-ray tube is capable ob being rotated around the breast for obtaining different projection views across a variety of angles. Thereafter, the images can be obtained from the projections through mathematical reconstruction. Moreover, this technique increases the visibility of breast lesions and offers highly accurate results.
