对妊娠滋养细胞肿瘤(gestational trophoblastic tumor,GTT)患者血清β—HCG测定作为诊断及评价化疗效果的有效而特异的指标定性。用灰阶超声观察,提供了该病病灶的形态信息定位,80年代以来已有应用彩色超声检查有关GTT的影像学报道,但有关GTT血流特点对诊断及化疗后随诊的报道不多。本研究旨在应用彩色多普勒超声技术检测GTT病灶及子宫部位血流的特点,探讨该项技术在诊断、鉴别诊断及治疗后随诊的价值。
Serum β-HCG in patients with gestational trophoblastic tumor (GTT) is an effective and specific indicator for the diagnosis and evaluation of chemotherapeutic effects. Ultrasound with grayscale provides the morphological information of the lesion. Since the 1980s, color sonography has been used in imaging studies of GTT. However, there are few reports about the characteristics of GTT blood flow in diagnosis and follow-up after chemotherapy. The purpose of this study is to evaluate the characteristics of blood flow in GTT lesions and uterine region by color Doppler ultrasound and to explore the value of this technique in diagnosis, differential diagnosis and follow-up after treatment.
