目的探讨超声造影(CEUS)成像时间-强度曲线(TIC)新指标对甲状腺良恶性结节的诊断价值。方法回顾性分析67个甲状腺结节造影成像TIC曲线,记录结节内感兴趣区(ROI)峰值强度(IMAX)、始增时间(RT)、达峰时间(TTP),以周围甲状腺组织ROI为基准,得到病灶相对IMAX(△Ι)、相对RT(△RT)、相对TTP(△TTP)。结果甲状腺良性结节IMAX、△Ι(142.6±55.6,46.3±55.4)明显大于恶性结节(75.2±34.7,-17.7±34.9)(P<0.05),△RT、△TTP(-0.3±1.7,-0.4±1.6)明显小于恶性(<1cm)结节(0.8±1.9,0.7±1.8)(P<0.05)。恶性(>1cm)结节△RT(-0.4±1.3)明显小于恶性(<1cm)结节(0.8±1.9)(P<0.05)。结论超声造影成像有助于甲状腺结节良恶性的鉴别诊断。
Objective To investigate the diagnostic value of new CEUS imaging time-intensity curve (TIC) in benign and malignant thyroid nodules. Methods The TIC curves of 67 thyroid nodules were retrospectively analyzed. The peak intensity of ROI (IMAX), time to onset (RT) and peak time (TTP) were recorded. The ROI of the thyroid gland Reference, the lesion relative IMAX (△ Ι), relative RT (△ RT), relative TTP (△ TTP). Results The thyroid benign nodules, IMAX, △ Ι (142.6 ± 55.6, 46.3 ± 55.4) were significantly higher than those of malignant nodules (75.2 ± 34.7, -17.7 ± 34.9), △ RT, △ TTP -0.4 ± 1.6) was significantly less than malignant (<1cm) nodules (0.8 ± 1.9,0.7 ± 1.8) (P <0.05). Malignant (> 1cm) nodules △ RT (-0.4 ± 1.3) was significantly less than malignant (<1cm) nodules (0.8 ± 1.9) (P <0.05). Conclusion Contrast-enhanced ultrasound is helpful for the differential diagnosis of benign and malignant thyroid nodules.
