| 目的 探讨声触诊组织成像(VTI)技术鉴别甲状腺良恶性钙化结节的价值。 方法 分析53例共58个甲状腺钙化结节的二维图像和弹性成像图,根据弹性图像灰度,将VTI图像分为6级,粗大钙化、分级≤3级判断为甲状腺良性钙化结节,微钙化、分级>3级判断为恶性钙化结节,并与术后病理结果对比。 结果 甲状腺良恶性结节之间的钙化类型差异有统计学意义(χ2=13.04,P<0.005);以微钙化诊断恶性结节的敏感度、特异度、准确率分别为74.29%(26/35)、73.91%(17/23)、74.14%(43/58)。甲状腺良恶性钙化结节之间VTI分级的差异有统计学意义(χ2=33.29,P<0.005);以VTI分级>3级诊断恶性结节的敏感度、特异度、准确率分别为85.71%(30/35)、91.30%(21/23)、87.93%(51/58)。 结论 VTI技术对鉴别甲状腺良恶性钙化结节有所帮助。 |

| Objective To explore the value of virtual tough tissue imaging (VTI) in identifying benign and malignant thyroid calcified nodules. Methods Two-dimensional images and elasticity images of 58 thyroid calcified nodules of 53 patients were analyzed. The images of VTI were divided into 6 grades based on the elastic image gray. Coarse calcifications and grade ≤3 nodules were considered as benign, and micro calcifications and grade >3 nodules were considered as malignant. VTI of all nodules were compared with corresponding pathological results. Results There was difference on the type of calcification between benign and malignant thyroid nodules (χ2=13.04, P<0.005). The sensitivity, specificity and accuracy of diagnosing malignant nodules by micro calcifications was 74.29% (26/35), 73.91% (17/23) and 74.14% (43/58), respectively. There was difference on VTI grade between thyroid benign and malignant calcified nodules (χ2=33.29, P<0.005). The sensitivity, specificity and accuracy of diagnosing malignant nodules by VTI grading >3 was 85.71% (30/35), 91.30% (21/23) and 87.93% (51/58), respectively. Conclusion VTI is helpful to identification of thyroid benign and malignant calcified nodules. |
