Medical physicists who have not worked in mammography for two years or more after meeting the initial requirements need to work under direct supervision when they return to mammography, if they do not meet the continuing experience and continuing medical education (CME) requirements. While under direct supervision, these personnel must obtain the necessary continuing experience and CME to requalify before resuming independent work in mammography. 21 C.F.R. 900.12(a)(3)(iv). A facility may be cited during an inspection if such personnel work without supervision prior to obtaining sufficient hours of CME and continuing experience to meet the continuing requirements. Similarly, facilities should check to see that all new personnel meet all the appropriate requirements prior to letting them provide mammographic services independently. If these personnel are working independently and do not have the required continuing experience and CME, the facility may be cited for these problems.
