| 摘 要： | 目的 探讨超声造影对甲状腺良恶性结节的鉴别诊断意义.方法 分析32例甲状腺良恶性结节超声造影的灌注过程,通过时间-强度曲线进行分析,比较结节及周围正常腺体及良恶性结节间造影剂到达时间(AT)、达峰时间(TTP)、峰值强度(PI)参数的差别.结果 12例甲状腺乳头状癌造影后表现为结节早于周围实质开始增强及消退,与邻近甲状腺实质比较呈高增强,甲状腺乳头状癌超声造影参数AT、TTP、PI分别为(7.49±4.45)、(17.41±2.84)、(18.56±5.24)s,与20例结节性甲状腺肿各项参数分别为(13.22±3.30)、(20.92±2.59)、(19.15±5.47)s]比较差异均有统计学意义(P<0.05).结论 超声造影技术可以为鉴别甲状腺良恶性结节提供更多有效的定量分析方法.

| Abstract: | Objective To analyse the sonographie characteristics of thyroid nodules after injection and investigate the contrast enhanced ultrasonography. Methods Analysed the sonographic characteristics in 32 cases and observed the dynamic enhancement pattern of nodules by the time-intensity curve(TIC). The evaluated parameters were arrival time (AT), time to peak(TTP), peak intensity(PI). Results Thyroid cancer (12 cases) showed early wash in an early wash out in comparison with the adjacent thyroid parenchyma, and the enhancement intensity AT(7.49 ± 4.45), TIP( 17.41 ± 2.84), PI( 18.56 ± 5.24) s] were lower than nodular goitre (20 cases) AT ( 13.22 ± 3.30), TIP (20.92 ± 2.59), PI ( 19.15 ± 5.47 ) s ] (P < 0.05 ). Conclusion The contrast enhanced ultrasonography may provide a useful method for the diagnosis of thyroid cancer. |
