Summary
Can acquisition of mammography images within the mammography screening program also
be carried out in screening units by medical assistants with the necessary knowledge
of radiation protection under remote/digital medical surveillance without loss of
quality? This non-inferiority study was approved by the radiation protection authorities and
addresses this question by evaluating the mammography examinations of 37808 screening
participants who were examined by a total of 14 technicians over a period of 18 months.
The following radiation protection-related endpoints were assessed: image quality,
repetitions, average glandular dose and examination abortions, each in comparison
of the examinations performed by 4 medical assistants (MA) vs. 10 radiologic technologists
(RT) on 4 mammography devices from the same manufacturer, 2 of which were used at
a stationary location under direct supervision of a medical doctor, and 2 in mobile
screening units under remote supervision. The quality requirements for the acquisition of screening mammography images are regularly
met by all technicians, regardless of their professional group and form of surveillance. The study results not only prove the non-inferiority of qualified MAs but also show
a significant superiority of MAs in terms of image quality and repeat exposures in
the present study. The acquisition of images in the mammography screening program for early detection
of breast cancer can be carried out by qualified medical assistants with the necessary
knowledge of radiation protection under remote surveillance without loss of quality.
