WebApr 11, 2024 · The DLP values for the coronary CT alone were 195 mGy*cm, corresponding to an effective dose of 2.7 mSv using the conversion k-factor for the chest CT scans (0.014 mSv/mGy*cm) or an effective dose of 5.1 mSv using the conversion k-factor recently postulated for the cardiac CT scans (0.026 mSv/mGy*cm). WebApr 18, 2024 · Effective dose can be estimated based on the DLP using the method described in the American Association of Physicists in Medicine (AAPM) Report No. 96, The Measurement, Reporting, and Management of Radiation Dose in CT, January 2008. In your case the effective dose from the head CT is around 1.5 mSv. Kent Lambert, CHP, FHPS new ocia book
