CT dose index and patient dose: they are not the same thing

Radiology. 2011 May;259(2):311-6. doi: 10.1148/radiol.11101800.

Abstract

Estimates of individual patient risk, and epidemiologic studies assessing potential late effects, must use patient size–specific dose estimates—they cannot use only scanner output (volume CT dose index or dose-length product).
