Patient Q & A: Digital Mammographic Imaging Screening Trial
Why doesn't your facility offer digital mammography?
Two previous studies comparing film mammography to digital mammography did not show increased detection. As a result, up to now, there was no compelling reason to invest in more expensive digital machinery, the cost of which would have eventually been passed on to patients.
Is digital mammography better than film?
Overall there was no difference in detection rates. Only in certain groups was digital shown to be better: women under 50, pre- and perimenopausal women, as well as women with dense breasts. Also, there is no information as of yet, whether survival rates were increased as a result of the higher detection rates and there is no specific information as of yet, as to the types of cancers that digital or standard mammography may be better at detecting.
Should I switch to a facility that provides digital mammography?
The type of mammography unit is only one factor that influences benefit from the examination. Women should have their mammograms read by a radiologist in whom they, and their physician, have the most confidence.
Should I still have my mammogram performed annually?
Women ages 40 and above should have their mammogram every year. The length of time between mammograms should not be extended in order to change facilities in search of digital technology.
Is the radiation dose lower with digital technology?
Although digital technology utilizes slightly lower levels of radiation, dosage levels used in both exams are safe and are the lowest necessary to still obtain high-quality results.
