Many consider the paradigm of "personalized medicine" to be new but it has long been applied to the practice of vascular CT. In this seminar, we will discuss how the many technical parameters governing power injection, scanning, and reconstruction can be changed to customize a CT protocol that is best for each individual patient. Issues covered will include clinical indication, renal insufficiency, radiosensitivity, extremes of body habitus, difficult venous access, and surgical alteration of anatomy, as well as patient convenience and comfort.
After this seminar the participating technologist or physician trainee will be able to identify patient factors that need be considered before a vascular CT examination and then work with the supervising physician to tailor pre- and post-examination interventions, contrast media dose, injector program, and scan protocol to each specific patient. The participant will also be taught how to reconstruct axial images in a way that takes into account patient specific factors, such as calcium distribution, image noise, and patient dimensions, to ease postprocessing and interpretation.
This webinar is presented by Dr. Michael Winkler, Assistant Professor of Radiology and Internal Medicine (Cardiology) and Mr. Karsten D. Colwell, BA, RT(R/CT/MR/ARRT), SCCT Technologist Certificate of Competency Recipient.
Dr. Winkler is a faculty member of the Gill Heart Institute at the University of Kentucky. Dr. Winkler received his medical degree from the University of Chicago, Pritzker School of Medicine and completed his residency and fellowship at the University of California at Los Angeles Medical Center. His areas of interest include CT imaging of atherosclerosis, and pre- and post-operative CT imaging support for endovascular procedures and surgeries. His research efforts relate to venous access for cardiovascular CT and cardiovascular imaging education.
Mr. Colwell is the Lead Cardiovascular Technologist at the University of Kentucky's Gill Heart Institute. He received his Bachelor's degree in Healthcare Administration from Midway College, Kentucky. He has trained many technologists, residents, and fellows in the practical aspects of cardiovascular CT, and has helped develop cardiovascular protocols used in many parts of the Commonwealth of Kentucky.
This webinar is supported through an unrestricted educational grant from SIEMENS Healthcare.
