The supervising physician need not be present during the initial reading and interpretation. Direct supervision for an interpreting physician means that during the joint interpretation of mammograms, the supervising interpreting physician reviews, discusses, and confirms the diagnosis of the physician being supervised. The supervising physician must review and, if necessary, correct the final interpretation before it is given to the patient or referring physician. 21 C.F.R. 900.2(o)(1). Since a qualified interpreting physician must sign each mammography report, the name of the supervising interpreting physician must be on the report as the interpreting physician. The facility has the option of including on the report, the name of the physician being supervised.
