Image Wisely is a joint initiative of the American College of Radiology, Radiological Society of North America, American Society of Radiological Technologists and American Association of Physicists in Medicine.

Case 7: Patient Skin Dose with Interventional Fluoroscopy: Metrics, C-Arm Geometry and Spectral Filtration

Emphasizes awareness of skin dose during interventional fluoroscopy, use of metrics, C-arm geometry and special filtration to optimize dose.

Authors: W. Pavlicek; R.G. Paden; T. Boltz; J. Hanson

Audience: Radiologists, radiologic technologists and medical physicists working with interventional fluoroscopy

This educational activity is free.

Objectives
Upon completion of this case, the participant will be able to:

  1. Identify the single most important tableside reported dose quality assurance (QA) metric for potential of skin tissue reactions, i.e. skin erythema
  2. Locate the patient exposure reference point (PERP) on the most commonly used interventional radiology (IR) C-arm configuration
  3. Utilize C-arm, table and detector geometry to minimize unnecessary skin dose to the patient
  4. Incorporate the use of spectral filtration, especially copper spectral filtration as a skin dose savings technique
  5. Identify the limitations of cumulative air kerma (CAK) as a surrogate for peak skin dose (PSD)

CE Credit Information
Image Wisely Radiation Safety Cases have been approved by the Commission on Accreditation of Medical Physics Education Programs, Inc. (CAMPEP) for MPCEC, Accreditation Council for Continuing Medical Education (ACCME) for Cat. 1 CME, and by American Registry of Radiologic Technologists (ARRT) for Cat. A CE. Case 10 (Child-sizing CT Dose) is 1.0 credit hours; all other cases are 0.5 credit hours. All Image Wisely Radiation Safety Cases are designated SA-CME by the American Board of Radiology (ABR) and qualify toward fulfilling requirements for Maintenance of Certification (MOC) Part II: Lifelong Learning and Self-assessment for physicians and medical physicists.

There is no charge to participate in this educational activity. For CE credit tracking and reporting, you will be redirected to the ACR website to log in or register and add the free module to your shopping cart for $0. Step-by-step instructions on accessing the case are available here.
