Abstract: Gestational trophoblastic disease（GTD）is a group of heterogeneous diseases characterized by abnormal proliferation of trophoblastic tissue，which is a rare disease，including both benign and malignant forms，and the latter are collectively referred to as gestational trophoblastic tumors（gestational trophoblastic neoplasia，GTN）. Imaging examinations are essential in the early diagnosis of GTD，especially in the identification of benign or malignant GTD，tumor staging and risk assessment，which play a crucial role in the localization and estimation of lesions in GTD patients，as well as in the choice of treatment.  It provides an evidence for judging prognosis，and can dynamically observe the effect of chemotherapy and recurrence，which has high clinical application value for the diagnosis of trophoblastic diseases.Transabdominal and transvaginal ultrasonography with duplex Doppler assessment are often appropriate adjuncts in any of these settings and in post-treatment monitoring. The use of broader imaging techniques depends on the diagnosis of GTN and other factors.

摘要： 妊娠滋养细胞疾病（gestational trophoblastic disease，GTD）是一组以滋养细胞组织异常增殖为特征的异质性疾病，是一种罕见疾病，包括良性和恶性两种形式，后者统称为妊娠滋养细胞肿瘤（gestational trophoblastic neoplasia，GTN）。影像检查在GTD早期诊断必不可少，尤其在 GTD 良恶性的鉴别、肿瘤的分期及风险评估方面起着至关重要的作用，能对GTD患者的病变定位和估测范围，为治疗方案的选择和判断预后提供依据，且能动态观察化疗效果及复发情况，对滋养细胞疾病的诊断有很高的临床应用价值。使用双功能多普勒的经腹和经阴道超声评估通常在上述任何一种情况下和治疗后监测中都是合适的辅助检查方法。更广泛成像技术的应用取决于 GTN 的诊断和其他因素。
