Summary
Radiologists primarily use film-screen mammography, with many switching technologies. Most monitor equipment doses and offer screening mammograms, but few teach breast self-examination or offer reduced fees.
Area of Science:
- Radiology
- Medical Imaging
- Breast Imaging
Background:
- Mammography practices vary among radiologists.
- Technological advancements have influenced mammography methods.
Purpose of the Study:
- To survey current mammography practices among radiologists.
- To identify trends in mammography technology adoption and screening protocols.
Main Methods:
- A survey was distributed to 319 radiologists regarding their mammography practices.
- Data collected included employment setting, imaging technology used, equipment upgrades, dose monitoring, and screening protocols.
Main Results:
- Film-screen mammography is the most common (54%), with 62% of respondents having changed methods in the last decade, often switching to film-screen.
- Most radiologists (71%) purchased new equipment after 1983 and monitor equipment doses regularly.
- Screening mammography commonly involves two-view examinations (87.4%), requires a referring physician (92%), and is infrequently offered to self-referred patients (28%) or at reduced fees (12%).
- Breast sonography is used by 53% but not for screening. A significant need for postgraduate training in mammography was identified.
Conclusions:
- Film-screen mammography remains dominant, with ongoing shifts in technology adoption.
- Current screening practices emphasize standardized protocols and physician referrals.
- There is a strong demand for enhanced continuing education in mammography for both radiologists and technologists.
