CT dose metric combining CTDIvol and scan length (units milligrays times centimetre)
Expansion
Dose-Length Product
Purpose
Used to calculate organ dose and effective dose
Clinical Context
DLP equals CTDIvol times scan length (centimetres). Multiply by k-factor (0.014 to 0.015 for abdomen) to estimate effective dose in mSv.

Key Points
- DLP is reported on every CT; multiply by conversion factor (k) to estimate effective dose
