When doing magnification mammography, can a facility keep the grid in place but position the cassette on top of the patient support (to prevent the grid from interfering with the image) and still meet the requirement for doing magnification procedures with the grid removed?

Yes, however, under these conditions the system must still be capable of providing magnification within the range of 1.4 to 2.0. A facility meets the requirement if it has a written procedure for (or can demonstrate that the system has the capability of) conducting mammography with and without a grid between the image receptor and the x-ray source and such a practice does not cause the system to fail any other applicable requirement. A medical physicist may be consulted regarding the appropriateness of the technique.
