Computed tomography laser mammography (CTLM) is the trademark of Imaging Diagnostic Systems, Inc. (IDSI, United States) for its optical tomographic technique for female breast imaging. This medical imaging technique uses laser energy in the near infrared region of the spectrum, to detect angiogenesis in the breast tissue. It is optical molecular imaging for hemoglobin both oxygenated and deoxygenated. The technology uses laser in the same way computed tomography uses X-Rays, these beams travel through tissue and suffer attenuation. A laser detector measures the intensity drop and the data is collected as the laser detector moves across the breast creating a tomography image. CTLM images show hemoglobin distribution in a tissue and can detect areas of Angiogenesis surrounding malignant tumors, that stimulate this angiogenesis to obtain nutrients for growth. History Breast cancer affects 1 in 8 women, and an estimated 27% of people live at least 5 years after being diagnosed with Stage IV cancer according to the National Cancer Institute. Mammography is the most commonly used method to screen for cancer, but there are three major drawbacks. The first is ionizing radiation. Since mammography uses low-energy x-rays to image the breast, the breast is exposed to ionizing radiation. Too much repeated exposure can elevate the risk of cancer down the road. The second drawback is inaccuracy. Mammography has low specificity and this can lead to false positives, which detect abnormalities that never progress to cause symptoms or death and also false negatives, especially in dense breast tissue, when it is especially difficult to detect tumors. 60 to 80 out of every 100 biopsies performed after mammography are actually negative for cancer. And lastly, pain is a major drawback to mammography. 23-95% experience discomfort, and pain is a significant inhibitor to re-attending screenings. CTLM was therefore developed as an alternative to X-Ray mammography. Its technology is based on two important principles: Different tissues have different absorption coefficients Malignant tumors have high rates of neovascularization Neovascularization is the natural formation of new blood vessels. Ultimately, there are multiple benefits to this developing technology. It is fast, only taking 15-20 minutes per picture and it uses non-ionizing near-infrared light, which allows patients to take repeat images. It also suspends the breast, which prevents pain while imaging. Currently, it is undergoing FDA approval, and it being proposed as an adjunct to mammography.
