Mammographers use ionizing radiation to create images of the breast for breast cancer screening and diagnostic purposes. They work in hospitals, clinics, labs, and outpatient centers.
Technologists working in mammography use low-dose x-rays to help identify masses and other abnormalities in and around the breast. Mammographers must be highly accurate in their positioning and exposure techniques in order to optimize the image and maintain radiation safety standards. ARRT certification and registration is voluntary, but those beginning a career in mammography will find that it is required by many healthcare employers.
ARRT doesn't provide a list of job postings within the profession. However, mammographers
seeking a position may want to check the ASRT JobBank.
Certification and Registration
The American Registry of Radiologic Technologists (ARRT) offers
certification and registration as part of its mission to recognize qualified individuals
in medical imaging, radiation therapy, and interventional procedures. To be eligible
for ARRT Mammography certification and registration, candidates must already hold ARRT certification and registration in Radiography, meet ethics requirements, document clinical experience, and pass the ARRT certification and registration examination in mammography.
Annual renewal of certification and registration is required to maintain the ARRT credential.
Continuing Education (CE)
Once certified and registered in mammography, Registered Technologists (R.T.s) must complete 24
Category A or A+ continuing education (CE) credits each biennium — a two-year period
that begins at the start of his or her birth month.
Technologists already certified and registered in a discipline who become certified and registered in additional disciplines maintain their original CE reporting schedule based upon their initial certification and registration. The continuing education requirement is 24 credits, regardless of the number of ARRT certificates held by a registrant. Technologists who become certified and registered in mammography within a biennium meet the CE requirement for that biennium.

In addition, any certifications and registrations earned in any category beginning January 1, 2011,
are time limited to 10 years, at which time R.T.s will need to demonstrate continued
qualifications as part of the
Continuing Qualifications Requirements (CQR).
