CT Scan: breast mammography camera to replace those
John. M. Pawnee United States University of California Davis Medical Center Doctor of Science, in his July 29, 2008 at the American Association of Physicists in Medicine 50th Annual Meeting that he invented a kinds of new equipment, called Dedicated Breast Computed Tomography (CT). The conference will be held in Houston in the United States.
Traditional mammography breast close to the camera require a cold metal plate. Some women, therefore there will be discomfort or even pain, they are also reluctant to do in time of breast cancer screening tests, and the resulting serious consequences.
Dedicated breast computed tomography scanning of the entire process is very gentle. You just lie face down on a table on a special trip, and the table so special is that it has a hole in the top, just so that one breast suspended. A special scanner to complete the examination in the breast around a week. The whole process with no pain, no feeling of constriction. Since then the use of computer technology to the breast, “broken down” into a layer of thin-layer organization, will be able to observe a very thorough breast lesions have had. Throughout the inspection process as long as a few seconds, the computer will be three-dimensional image reconstruction of the breast.
CT scanning began long ago applied to the brain, lung and abdominal examination were. But experts have not had breast CT scans showed their gratitude for fear of a common standard CT machines and equipment so that women exposed to excessive radiation environment. Pawnee and his colleagues invented a special device, called the CBBCT, check the radiation used in conventional mammography scans using the same amount of radiation.
So far, researchers at the University of California has 160 women examined both breasts with the new machines.
The team to demonstrate the new machine’s high-resolution, high-resolution can be carefully observed to ensure that people everywhere breast tissue. Pawnee is a medical physicist, he said that this new technology is expected to herald in the next 3-4 years, put into use.
“Dedicated breast CT examination masses is better than mammography,” Bonnie said at a news conference, “New technology will make the patient feel comfortable, and in the three-dimensional reconstruction of pathological damage there is a great improvement.”
The technology also has drawbacks. It can not detect small lesions, these small lesions are often prompted early breast cancer. Molybdenum photography at this point to do better than the new technology.
“Until now I never said that dedicated breast CT better than mammography camera,” Bonnie said.
Earlier this year, when the team began to study bone CT and PET technology can integrate new method, PET can help doctors evaluate this technique tumor metabolism, tumor cell’s metabolic rate is different from normal cells, in the PET examination can be displayed. Integration of these two techniques of equipment can help patients who have already confirmed a planned treatment.
“PET / CT has not carried out large-scale application of reason for this is expensive, but compared with the general examination, the patient exposure to high levels of radiation,” Bonnie said, “but they are three-dimensional mammography reconstruction after the great photography advantage of monitoring the treatment effect of the treatment is also useful. “
