About this Program

This program we will be discussing and demonstrating mammographic positioning techniques for the craniocaudal and mediolateral oblique views.   It is the goal and the responsibility of mammographers to strive to include as much breast tissue as possible while demonstrating the correct anatomy and pathology.  This program will provide you with the proper tools to enhance your current positioning 


Overview of Mammographic Positioning

  • Identify the two standard views for mammography - Optimal Craniocaudal (CC) and Mediolateral Oblique (MLO).
  • Describe the standard projections for CC and MLO.
  • Identify the limitations of the standard projections for CC and MLO.
  • Define the mobility principle in mammographic positioning.
  • Describe mammographic compression and its benefits.

Basic Mammographic Positioning – Craniocaudal (CC)

  • describe the mammographic positioning and compression techniques for Craniocaudal Oblique view.

Basic Mammographic Positioning – Mediolateral Oblique (MLO)

  • describe the mammographic positioning and compression techniques for Mediolateral Oblique view.

“This CE activity may be available in multiple formats or from different CE sponsors. ARRT does not allow self-learning CE activities (e.g., Internet courses, home study programs, directed readings) to be repeated for CE credit in the same CE biennium.”

How it Works:

  • Your On Demand CE activity that you purchased will be located in your “My Account” section once you log into the MTMI Website.
  • You have three attempts to pass each quiz.
  • You must earn a score of 75 % or higher.
  • Credit is recorded the day you submit and pass the quiz and is determined using Central time.
  • You have 30 days to complete and pass the quiz.
  • Once passed, access your MTMI “My Account” to print your “Certificate of Completion.”


Educational Objectives

By the end of this program, the participant should be able to:

  • Demonstrate proper positioning techniques for the craniocaudal and mediolateral oblique views in mammography.
  • Identify techniques that can be used to optimally visualize all posterior glandular tissue and retroglandular fat on the craniocaudal view.
  • Identify techniques that can be used to optimally visualize the posterior tissue, retroglandular fat and pectoral muscle on the mediolateral oblique views.
