【摘要】 目的：探究剖宫产术后早期子宫瘢痕妊娠阴道超声、磁共振成像(MRI)特征及诊断价值。方法：回顾性选取2022年1月—2023年12月丰城市中医院收治的剖宫产后疑似子宫瘢痕妊娠患者100例，其中52例经阴道超声检查作超声组，48例行MRI扫描检查作MRI组，比较两组成像特征及诊断价值。结果：超声组诊断敏感度(71.79%比97.06%)、准确度(71.15%比93.75%)和诊断时间[(32.75±5.64)min比(63.29±7.95)min]均低于MRI组，差异均有统计学意义(Plt;0.05)；但两组特异度(69.23%比92.86%)的比较，差异无统计学意义(Pgt;0.05)。超声组卵黄囊、胚芽和原始心管搏动检出率均高于MRI组，妊娠囊内出血、宫腔积血和局部瘢痕浸润检出率均低于MRI组，差异均有统计学意义(Plt;0.05)；但两组妊娠囊检出率比较，差异无统计学意义(Pgt;0.05)。结论：MRI在剖宫产术后早期子宫瘢痕妊娠中诊断价值高于阴道超声，在显示妊娠囊内出血、宫腔积血和局部瘢痕浸润方面具有优势，但阴道超声检测便捷，适用于早期筛查。

    Characteristics and Diagnostic Value of Vaginal Ultrasound and MRI in Early Uterine Scar Pregnancy after Cesarean Section/XIONG Yeye， XU Haiqing， ZOU Qi. //Medical Innovation of China， 2024， 21(31)： -175

    [Abstract] Objective： To explore the characteristics and diagnostic value of vaginal ultrasound and magnetic resonance imaging (MRI) in early uterine scar pregnancy after cesarean section. Method： A total of 100 patients with suspected uterine scar pregnancy after cesarean section in Fengcheng Hospital of Traditional Chinese Medicine from January 2022 to December 2023 were retrospectively selected. 52 cases undergoing vaginal ultrasound examination were selected as ultrasound group and 48 cases undergoing MRI scan were selected as MRI group. The imaging characteristics and diagnostic value in two groups were compared. Result： The diagnostic sensitivity (71.79% vs 97.06%) ......
