Abstract:
Objective To compare the value of three-dimensional tomography ultrasound imaging(3D-TUI)and MRI for diagnosng early cesarean scar pregnancy(CSP).Methods Seventy-six patients who had gestational week not more than 12 weeks and with clinically suspected CSP were retrospectively enrolled.According to surgical and postoperative pathological findings,the patients were categorized into CSP group(n=65)and non-CSP group(n=11).The diagnostic performance of 3D-TUI,MRI and the combination of these two for CSP,also the depiction of CSP characteristics of 3D-TUI and MRI were compared.Results The sensitivity,specificity,accuracy,positive predictive value and negative predictive value of combination of 3D-TUI and MRI for diagnosing CSP was 96.92％,90.91％,96.05％,98.44％and 83.33％,respectively,with the accuracy higher than that of 3D-TUI alone(P＜0.05).No significant difference of diagnostic efficacy was found between 3D-TUI and MRI(all P＞0.05).3D-TUI showed a higher accuracy rate than MRI for displaying yolk sac,embryo,villi invasion into local scars and implantation of villi into muscle layer(all P＜0.05),whereas MRI was more accurate for diagnosing intrauterine bleeding(P＜0.05).Conclusion 3D-TUI could be used as the preferred initial imaging examination for early CSP.Combining with MRI could further improve its diagnostic accuracy.
