Table 2 Diagnosis accordance of 64 colorectal carcinomas with postprocessing techniques

Postprocessing technique	Circumferential extent		Lesion length		Pathological pattern
	Case (n)	%	Case (n)	%	Case (n)	%
MPR	64	100.0	57	89.1	52	81.2
VC	53	82.8	49	76.6	59	92.2

^aP < 0.05 vs pathological pattern,

^bP < 0.01 vs circumferential extent and lesion length.
