Do the 3 months of mammography training have to be performed during the last two years of the residency program?
No. The regulations do not establish a time frame for meeting this requirement. The 3 months of training could have occurred anytime during the residency program (or outside the residency program, see discussion above). However, the initial experience (240 exams) and initial medical education (60 hours) must be obtained within the specified timeframes of the person’s starting date (21 CFR 900.12(a)(1)(i)(C)-(D)).
