Contrast-Enhanced Ultrasound Evaluation of Mifepristone for Treatment of Low-Risk Cesarean Scar Pregnancy

Table 3

Changes in blood flow around the gestational sac before vs. after mifepristone treatment in CSP and IUP patients.

Parameter	CSP (n = 23)	IUP (n = 23)	t
AT (s)	5.03 ± 2.97	4.65 ± 3.09	−0.424	0.674
PI (dB)	0.01 ± 1.78	0.15 ± 1.53	−1.115	0.271
AUC	210.69 ± 121.14	169.26 ± 74.06	−1.399	0.169

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