For those anxious about breast x-rays and their interpretation, the fact that there are fewer false positives as well as better chances for detecting cancers may be of some consolation.
The compression reduces the amount of radiation needed to penetrate the tissue and also spreads out the breast tissue to Tomosynthesis mammography equipment produce excellent images. Also note the warning that tomosynthesis has twice the raditation as a traditional mammogram, and radiation can cause cancer by itself.
NYT article on new study. Diagnostic mammography may also be done after an abnormal screening mammogram in order to evaluate the area of concern on the screening exam.
The trend toward more expensive digital imaging devices has picked up steam since the machines were allowed for use inso now more and more doctors are publicizing their acquisition of three dimensional mammography equipment. In this way, 3-D breast imaging is similar to computed tomography CT imaging in which a series of thin high-resolution "slices" are assembled together to create a 3-D reconstruction of the body.
Always inform your doctor or x-ray technologist if there is any possibility that you are pregnant. Do not wear deodorant, talcum powder or lotion under your arms or on your breasts on the day of the exam. Breast tomosynthesis overcomes some of the limitations of standard mammography, but it is not yet available in all imaging facilities.
Screening Mammography with Breast Tomosynthesis Mammography plays a central part in the early detection of breast cancers because it can often show changes in the breast years before a patient or physician can feel them. This allows the radiologist to quickly retrieve previous exams for comparison from year to year and to manipulate the images for complete viewing.
Installations of DBTs in hospitals totaled 3, inrepresenting a market value worth When it has become a challenge, ONsite has worked with the client practice to achieve a favorable outcome.
When a 2-D mammogram and 3-D mammogram are performed together, the study results in twice the radiation dose as from a 2-D mammogram alone - and the dose is greater in thicker breasts.
A Word About Minimizing Radiation Exposure Special care is taken during x-ray examinations to use the lowest radiation dose possible while producing the best images for evaluation.
The effective radiation dose for this procedure varies. X-rays pass through most objects, including the body.
Be sure to inform the technologist if pain occurs as compression is increased. Accordingly, they are some the most skilled and experienced interpreters of 2D mammography exams and 3D mammography studies.
These can be confused for calcium deposits on the mammogram. When the examination is complete, you may be asked to wait until the radiologist determines that all the necessary images have been obtained.Another, very convenient procedure that can be used is digital breast tomosynthesis (DBT).
Because DBT can be performed on equipment similar to currently used digital mammography equipment, it can offer an easy extension of the current digital screening mammography.
Breast tomosynthesis is an advanced form of mammography, a specific type of breast imaging that uses low-dose x-rays to detect cancer early when it is most treatable.

The Genius™ 3D Mammography™ exam (a.k.a. Genius™ exam) is acquired on the Hologic® 3D Mammography™ system and consists of a 2D and 3D™ image set, where the 2D image can be either an acquired 2D image or a 2D image generated from the 3D™ image set.
At Mass General Imaging, breast tomosynthesis plus digital mammography is standard protocol for all screening mammograms. As part of this commitment, we invest in the latest equipment to ensure that our fleet of scanners consistently delivers the lowest dose of radiation possible during an exam.
