Table 6 Comparison of SNR between 120 and 80 KVP

From: Studies on the radiation dose, image quality and low contrast detectability from MSCT abdomen by using low tube voltage

	SNR		Student t-test	p value
	120 KVP	80 KVP	Student t-test	p value
Mean ± SD	13.20 ± 4.32	4.88 ± 1.57	6.77	< 0.001*
Min–Max	6.14–21.36	2.01–6.79	6.77	< 0.001*

*means p < 0.05
