| 目的 对比三维断层超声成像(3D-TUI)与MRI诊断早期剖宫产瘢痕妊娠(CSP)的价值。方法 回顾性纳入76例停经≤12周且临床疑诊CSP患者,以手术及术后病理结果为依据分为CSP组(n=65)与非CSP组(n=11),对比3D-TUI、MRI及二者联合诊断CSP,以及3D-TUI与MRI显示CSP特征性表现的效能。结果 3D-TUI与MRI联合诊断CSP的敏感度、特异度、准确率、阳性预测值及阴性预测值分别为96.92%、90.91%、96.05%、98.44%及83.33%,二者联合诊断CSP的准确率高于单一3D-TUI(P＜0.05),而单一3D-TUI与MRI诊断效能差异均无统计学意义(P均＞0.05)。3D-TUI显示卵黄囊、胚芽,以及绒毛侵及局部瘢痕、绒毛植入肌层的准确率高于MRI(P均＜0.05),而MRI诊断孕囊内出血准确率高于3D-TUI(P＜0.05)。结论 3D-TUI可作为诊断早期CSP的首选检查方法;联合MRI可进一步提高诊断准确率。 |

| 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. |
