目的:探讨三维超声彩色血流能量图(3D-CPA)评价131I治疗甲亢后甲状腺功能的临床价值。方法:随机选取未经治疗的60例甲亢患者作为病例组,并按照131I治疗后3个月时的血清学指标将病例组分为未愈、缓解和甲减3组;另选30例正常人作为对照组,应用3D-CPA方法对甲状腺进行超声检查,获得3D-CPA定量指标,进行各组间比较分析。结果:131I治疗后平均灰阶指数(MG)为未愈组<缓解组<甲减组<对照组,血管指数(VI)、血管血流指数(VFI)为未愈组>缓解组>甲减组>对照组(P<0.01或P<0.05)。结论:3D-CPA可以定性、定量判定甲状腺内部回声及血流分布情况,对甲亢的诊断、预后评估、131剂量的更合理化选择均有重要临床意义。
Objective: To evaluate the clinical value of three-dimensional color doppler flow imaging (3D-CPA) in assessing thyroid function after 131I treatment of hyperthyroidism. Methods: Totally 60 untreated patients with hyperthyroidism were selected as the case group and the cases were divided into three groups according to the serological indexes at 3 months after 131I treatment: 30 cases of normal people As a control group, the thyroid was examined by 3D-CPA. The quantitative indexes of 3D-CPA were obtained and compared among groups. Results: The average grayscale index (MG) after 131I treatment was in the unhealing group (remission group, hypothyroidism group, control group, vascular index (VI), vascularity index (VFI) Group> control group (P <0.01 or P <0.05). Conclusion: 3D-CPA can qualitatively and quantitatively determine the internal echo and blood flow distribution in the thyroid gland. It is of great clinical significance for the diagnosis, prognosis assessment and more rational selection of 131 dose of hyperthyroidism.
