Overview
About this Webinar
Chest radiography still represents the largest, single-most radiography examination ordered by practitioners even with all of the choices available from the various medical imaging modalities. The simple chest radiograph delivers a high diagnostic yield of information, particularly when you consider its low cost and radiation dose, exam logistics and convenience. In this session we’ll look at the basic interpretive techniques used by radiologists to understand the information seen on a chest image. Concepts such as Silhouette Sign, hilar overlay sign, cardiac curves, and chest consolidations will be explored. The important role of the technologist will be emphasized to achieve optimum diagnostic yield.
Educational Objectives
At the conclusion of this webinar, attendees will be able to:
- Explain the radiologic interpretive principle based upon the five (5) radiographic densities
- Differentiate between the left and right hemi-diaphragm on a lateral chest radiograph, using the principle of five (5) radiographic densities
- Recognize abnormal chest radiographs using the Silhouette Sign concept
- Identify the general location of a chest consolidation using the silhouette sign and hilar overlay techniques
- Distinguish between the four (4) classes of radiographic chest consolidations
- Diagram the pulmonary acinus unit to explain the process of fluid collection and aeration in lung tissues
- Distinguish between the various patterns of lung consolidation
- Calculate the cardio-thoracic ratio as shown radiographically
- Recognize cardiomegaly on a chest radiograph
- Label the left and right cardiac curves as seen radiographically
- Identify various interpretive anatomical structures commonly seen on a chest radiograph
- Explain the important role the radiographer plays in optimizing chest image value and the consequences of sub-optimum image quality

Name
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.
