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.
