## Abstract

The Food and Drug Administration (FDA) is correcting its regulations governing mammography, published in a document entitled ``Quality Mammography Standards'' that appeared in the Federal Register of October 28, 1997. The regulations are effective April 28, 1999; except Sec. 900.12(b)(8)(i), (e)(4)(iii)(B), and (e)(5)(i)(B), which become effective October 28, 2002. The October 28, 1997, document was published with some inadvertent typographical errors. Some of those errors were corrected in a document entitled ``Quality Mammography Standards; Correction'' that appeared in the Federal Register of November 10, 1997, but additional typographical errors occurred in the publication of this document. In addition, since November 10, 1997, certain other problems with the text of the regulations have been identified that, if uncorrected, would lead to unforeseen and undesirable consequences. This document corrects those errors.
