Table 3

Comparison of ARD (mGy) for radiosensitive organs (Lung, Breast and Thyroid) between dose modulation imaging at 320-row MDCT versus dose modulation method at 64-row MDCT.

Locations	320-row scanner	64-row scanner	value
Left Lung	8.848	47.88	<0.001
Left Breast	10.84	43.17	<0.001
Thyroid (Left lobe-26)	0.057	2.091	<0.001
