Fat is Your Friend on Radiographs
About this Program
In this session, the role of fat as a radiographic diagnostic tool will be discussed. The five (5) basic radiographic densities will be introduced; in particular the low contrast resolution between water and fat radiographic densities. Adipose tissue is located throughout our bodies, and its radiographic visualization plays an important part in the diagnostic interpretive process for the radiologist. It is often under-appreciated and in this session we will look at its radiographic significance with various diagnostic imaging examinations including the elbow, wrist, knee ankle, abdomen and bony fractures.
Educational Objectives
Upon completion of this webinar, the participant should be able to:
- Identify the five(5) basic radiographic densities on any radiographic image.
- Explain the interpretive process of radiographic density visualization.
- Discuss low contrast resolution(LCR) and its importance in image interpretation.
- Explain the clinical importance of adipose in various body compartments, from a diagnostic viewpoint.
- Identify several body structures that demonstrate radiographic shadow formation based upon adipose distribution.
- Explain the radiographic clinical interpretive importance of adipose in the elbow, knee, ankle and wrist joints as well as the abdomen.
- Discuss the development of a lipohaemoarthrosis and its radiographic and clinical significance.
- Point out the process of tissue effusion and its impact upon fat visualization.
- Suggest methods/techniques that could be utilized to optimize LCR and adipose visualization.

Randy Griswold
MPA, RT(R)
Randy has been in the medical imaging profession for over 40 years as an educator, sales and marketing professional and consultant. Currently he is a contributing author and medical imaging consultant. Prior to that, he was the Director of Sales and Marketing for a Midwest distributor of digital medical imaging products. His collective experiences as an educator include being the Program Director for Bellin College, School of Radiologic Sciences and their BSRS program. He was instrumental in transforming their two-year certificate program to a four-year, accredited BSRS degree program.
Randy has 23 years of experience in radiology capital equipment sales, service and support including digital imaging, and has completed his graduate work in Public Service Administration with an emphasis in Health Care Administration and Medical Imaging Marketing. He is a past president of the Wisconsin Association of Educators in Radiologic Technology (WAERT) and the Wisconsin Society of Radiologic Technologists (WSRT) as well as being a Fellow. His passion for teaching is focused on helping technologists understand the importance of obtaining good quality images for diagnosis, in a fashion that uses the skills and techniques of radiologist interpretation.
