High-Pitch Computed Tomography Coronary Angiography—A New Dose-Saving Algorithm: Estimation of Radiation Exposure

Table 1

Effective radiation exposure of high-pitch CTCA using 100 kV and 120 kV.

Protocol	Effective dose male [mSv]	Effective dose female [mSv]	Total mAs	CTDIVol (mGy)	DLP (mGy cm)
1 (100 kV)	1.1	1.2	688	3.1	56
2 (120 kV)	1.6	1.8	689	5.2	95

CTDI_Vol: volume CT dose index; DLP: dose-length product.
