Sensitivity	CT colonography	Colonoscopy	P values
Advanced adenomas	92% (88–96)	96% (93–99)	P = 0.26

Adenomas and carcinomas 6–9 mm	78% (71–85)	97% (94–100)	P < 0.001
Adenomas and carcinomas 6–9 mm	108/138	134/138	P < 0.001
Adenomas and carcinomas ≥10 mm	93% (89–97)	97% (94–99)	P = 0.17
Adenomas and carcinomas ≥10 mm	171/184	178/184	P = 0.17
All lesions^a 6–9 mm	75% (69–81)	96% (93–99)	P < 0.001
All lesions^a 6–9 mm	142/190	190/198	P < 0.001
