	Cervical cancer with metastasis	Cervical cancer without metastasis	Normal cervix	p-value
SI before (×10−3)	1.40 ± 0.15	1.52 ± 0.12	1.39 ± 0.13	0.251
SI after (×10−3)	0.92 ± 0.14	1.19 ± 0.12	1.30 ± 0.11	0.001a
CNR	3.87 ± 1.45	2.33 ± 1.04	0.66 ± 0.31	0.002a

CNR, contrast-to-noise ratio; SI, signal intensity.
