摘要

目的：

探讨超声造影(contrast-enhanced ultrasound，CEUS)在甲状腺结节细针穿刺术(fine needle aspiration，FNA)中的应用价值。

方法：

选取临床可疑恶性甲状腺结节患者73例(共82个结节)，分别行常规超声引导下细针穿刺及超声造影引导下细针穿刺，穿刺针数406针，每个结节均手术并经病理证实。比较这两种方法诊断甲状腺癌的阳性率、穿刺阳性率。

结果：

73例患者的82个结节中，71个结节病理诊断为甲状腺癌。71个结节一共406针，其中315针(77.6%，315/406)诊断为甲状腺癌。常规超声引导下细针穿刺诊断为甲状腺癌者56个(78.9%，56/71)，151针诊断为甲状腺癌，细针穿刺术的灵敏度47.9%，特异度81.3%，准确率55.4%，阳性预测值71.9%，阴性预测值60.9%。超声造影引导下细针穿刺诊断为甲状腺癌者69个(97.2%，69/71)，263针诊断为甲状腺癌，细针穿刺术的灵敏度83.5%，特异度80.2%，准确率82.8%，阳性预测值80.8%，阴性预测值82.9%。两种方法之间差异有显著统计学意义。

结论：

超声造影能提高甲状腺癌诊断的成功率，提高细针穿刺的灵敏度和准确率，引导细针穿刺避开结节内坏死、囊性无血供区域，提高穿刺取材准确率，具有较高的临床应用价值。

Abstract

Objective:

To investigate the application value of thyroid fine needle aspiration (FNA) biopsy guided by contrast-enhanced ultrasound (CEUS).

Methods:

A total of 73 patients with 82 thyroid nodules which were suspected thyroid carcinoma were enrolled in the study. The puncture biopsies of the suspicious lesions guided by CEUS and conventional ultrasonography were conducted. The diagnoses were confirmed by pathological results. The positive rates of thyroid carcinoma and puncture points were detected by the two met

hods.

Results:

In 82 nodules with 406 punctures

71 nodules and 315 punctures were pathologically diagnosed as thyroid carcinoma. In the 71 nodules diagnosed as thyroid carcinoma

69 and 56 nodules were detected by CEUS and conventional ultrasound

respectively. The sensitivity

specificity

accuracy

positive predictive value and negative predictive value of aspiration biopsy guided by CEUS were 83.5%

80.2%

82.8%

80.8%

82.9%

and of conventional ultrasound were 47.9%

81.3%

55.4%

71.9%

60.9%. There was a significant difference between the two methods.

Conclusion:

CEUS guidance can improve the accuracy of diagnosing thyroid carcinoma and the sensitivity and accuracy of the puncture. It can aviod the necrosis and cystic area with high clinic value.
