Measured Head CT/CTA Skin Dose and Intensive Care Unit Patient Cumulative Exposure.
R D NawfelGeoffrey S YoungPublished in: AJNR. American journal of neuroradiology (2017)
Directly measured radiation skin doses from head CT/CTA patient examinations are substantially lower than volumetric CT dose index. Measured peak skin dose confirms that multiple head CT/CTA examinations in representative patients in the neurological intensive care unit may produce cumulative doses exceeding the single-dose deterministic threshold for skin injury.
