What Do Those T and Z Scores Mean? A Bone Densitometry Primer

Rodney Fisher, Ph.D., RT(R)(N)(CT)(BD), CNMT, Assistant Professor; Midwestern State University

On Demand | Expires 7/1/2023

*Approved by the ASRT for 1 Category A continuing education credit.

Bone Densitometry in the form of a DEXA exam is a common study performed by most radiology departments. But with few formal training programs available, most technologists learn how to perform DEXA exams “on the job”. This informal training means many staff members may not fully understand the significance of the T and Z scores they generate for radiologists.

In this presentation, participants will learn how to interpret T and Z scores in order to produce the highest-quality diagnostic studies. We’ll explore the inner workings of the DEXA exam, standard definitions related to the field, calculations for T and Z scores and how to use these scores to improve the quality of studies.

Learning Objectives:

Upon completion of the seminar, participants will be able to:

  • Discuss osteoporosis
  • Understand what T and Z scores are
  • Use T and Z scores to generate higher quality diagnostic exams
