Diagnostic radiology and nuclear radiology program requirements changes challenged.

I n November 2011 and in March 2012, the American Board of Nuclear Medicine (ABNM), SNM, American College of Nuclear Medicine (ACNM), and Nuclear Medicine Residency Review Committee (NM RRC) of the Accreditation Council for Graduate Medical Education (ACGME) challenged a recent change to the diagnostic radiology (DR) residency program requirements and proposed changes to the nuclear radiology fellowship program requirements. The purpose of this article is to outline the basis for these challenges and to describe the ACGME process for mediation.
