Image quality and radiation levels in videofluoroscopy for swallowing studies: A review

Research output: Contribution to journalReview article

Abstract

Inexpensive video recording equipment coupled to conventional x-ray fluoroscopes is now in widespread use by clinicians for the evaluation of patients with swallowing disorders. The prevalence and simplicity of this apparatus have encouraged its use by clinical specialists who are often not specifically trained in the safe use of x-ray equipment, and this may not be in the best interest of either the patient or the examiner. This has prompted an overview of the operating principles of videofluorescopy equipment. The factors governing image quality are discussed as well as potential hazards and protective measures for both patients and operator. A method of estimating the radiation dose to sensitive tissues from a typical swallowing study is included.
