目的探讨超声造影技术在声脉冲辐射力(ARFI)诊断“灰带”甲状腺结节诊断中的价值。方法对70例行甲状腺切除手术患者的200个甲状腺结节,术前行声脉冲辐射力检查。其中40个VS值在2.5~3.0m/s之间甲状腺结节良恶性鉴别困难者(简称“灰带”结节)行超声造影。结果 ARFI对200个甲状腺结节的诊断准确率为82%(164/200),其中40个声脉冲辐射力诊断“灰带”甲状腺结节诊断准确率为70%(28/40),超声造影对40个声脉冲辐射力诊断“灰带”甲状腺结节诊断准确率为90%(36/40),两种方法诊断准确率之间有显著差异(P<0.05)。结论超声造影对于声脉冲辐射力诊断“灰带”甲状腺结节有着更高的诊断准确率,在临床工作中,可以作为ARFI的补充。
Objective To investigate the value of contrast-enhanced ultrasound (CEUS) in the diagnosis of “acoustic pulse radiation (ARFI)” and “gray band” thyroid nodules. Methods Totally 200 thyroid nodules in 70 patients with thyroidectomy underwent acoustic pulse radiation before operation. 40 of which 40 VS values between 2.5 ~ 3.0m / s thyroid nodules benign and malignant differential identification (referred to as “gray zone ” nodules) line ultrasound contrast. Results The accuracy of ARFI in diagnosing 200 thyroid nodules was 82% (164/200). Forty cases were diagnosed by acoustic pulse radiation and 70% (28/40) in diagnosis of “gray zone” thyroid nodules. The diagnostic accuracy of contrast-enhanced ultrasound was 40% (36/40) for the diagnosis of 40 acoustic pulses, and the diagnostic accuracy of the two methods was significantly different (P <0.05). Conclusion Contrast-enhanced ultrasound (CEUS) has a higher diagnostic accuracy for the diagnosis of “pulsed” thyroid nodules with acoustic pulse radiation, which can be used as an adjunct to ARFI in clinical practice.
