Table 2

CEUS perfusion quantification before and after mifepristone treatment in CSP and IUP patients.

Group	Parameter	Before mifepristone treatment	After mifepristone treatment	t
CSP (n = 23)	AT (s)	18.42 ± 3.38	13.39 ± 1.98	8.117	≤0.001
	PI (dB)	17.68 ± 2.84	14.48 ± 2.81	6.446	≤0.001
	AUC	1011.03 ± 194.53	800.33 ± 109.41	8.341	≤0.001
IUP (n = 23)	AT (s)	18.71 ± 2.01	14.06 ± 2.85	7.208	≤0.001
	PI (dB)	17.85 ± 2.61	15.47 ± 2.44	4.411	≤0.001
	AUC	1041.76 ± 168.14	878.49 ± 162.23	10.961	≤0.001

AT, arrival time; AUC, the area under the time intensity curve; CEUS, contrast-enhanced ultrasonography; CSP, cesarean scar pregnancy; IUP, intrauterine pregnancy; PI, peak intensity.
