Computed Tomography Laser Mammography (CTLM)

Computed Tomography Laser Mammography (CTLM) is a relatively new and very promising field of optical imaging. In combination with conventional mammography and other techniques, it has the power to provide detailed information of breast abnormalities. It provides unique images of blood flow to the breast, allowing detection of any new blood vessels in the breast which is a hallmark of developing tumors. This information on angiogenesis in the breast tissue can help physicians differentiate between benign and malignant tumors, thereby giving them more information for a proper diagnosis [2].

OPTO-ACOUSTIC BREAST IMAGING

Schematic representation of opto-acoustic breast imaging

Opto acoustic breast imaging is a new generation diagnostic tool currently in the clinical trial stage for diagnosis of malignant or benign breast lumps. According to a European journal of breast cancer around 4 million new cases of breast cancer are detected every year with almost 80 percent of them turning out to be benign on laboratory testing. It is difficult for radiologists to rule out malignancy at the imaging stage. The cost of conducting surgical or core needle biopsy for every suspicious lump outweighs the results especially in women coming from struggling economies. A low cost diagnostic tool such as opto acoustic imaging can help in the timely detection of breast cancer in the early stages and also help prevent and control the increasing mortality due to this disease in developing as well as developed countries.
