彩超诊断甲状腺恶性肿瘤30例临床观察(1)
[摘要] 目的：探讨高频超声与彩色多普勒超声对甲状腺癌的诊断价值。方法：分析30例经手术病理证实为甲状腺癌的患者的声像图特征。结果：腺癌病灶呈低回声和内部有细粒状钙化灶是特征性较高的甲状腺癌的超声表现，本病的高频声像图多数实质肿块及囊性肿块内实质部分有沙粒状钙化或粗糙钙化光团，少数表现为增强及杂乱回声肿块。彩色多普勒血流成像(CDFI)，血流阻力指数(RI)和收缩期最高流速峰值(Vmax)较高。结论：高频超声及彩色多普勒超声对甲状腺癌的诊断具有较大的价值。

[Abstract] Objective: To explore the high-frequency ultrasound and color Doppler ultrasound diagnosis of thyroid cancer. Methods: 30 cases confirmed by pathology in patients with thyroid cancer, analyzed their sonographic features. Results: The lesions were hypoechoic cancer and it had a fine granular calcification was a characteristic of thyroid cancer, ultrasound high performance, high-frequency sonography of the disease and cystic mass in the majority of real substance of the mass was calcified with sand or granular coarse calcification Light Mission, a small number of performance and clutter to enhance the echo mass. Color Doppler flow imaging (CDFI), blood flow resistance index (RI) and the highest systolic peak velocity (Vmax) were high. Conclusion: High frequency ultrasound and color doppler ultrasound diagnosis of thyroid cancer have greater value.

甲状腺癌是内分泌恶性肿瘤，占人体所有恶性肿瘤的1.3%[1]，发病率较高，预后很差，甲状腺癌必须早期发现并手术治疗。本文通过对手术病理证实的30例甲状腺癌患者行高频超声检查，分析高频声像图表现及彩色多普勒显像特点，进一步探讨其对甲状腺癌的诊断价值，以提高甲状腺癌超声定性诊断的水平，现报道如下：
1资料与方法
1.1一般资料
本组30例患者均为本院2007年3月~2009年11月收治的甲状腺癌患者，均经手术病理证实，全部患者术前行彩超检查，其中，女性23例，男性7例，年龄21～74岁，平均46岁。其中，乳头状癌腺癌27例，腺癌1例，髓样癌1例，未分化小细胞癌1例。
1.2 方法
采用美国惠普HP5500彩色超声诊断仪，频率为7~10 MHz的宽高变频探头。患者取仰卧位，垫高颈肩部，充分暴露颈前区，探头置于颈前部，由甲状软骨下方自上而下滑行，常规检查甲状腺，观察有无肿大结节，若有则观察病灶的大小、数目、位置、类型、内部回声有无衰减，有无晕环，然后做彩色多普勒血流检查，观察病灶内的彩色血流、血流分级情况，于病灶内部和周边多点取样进行多普勒流速曲线测量并记录动脉收缩期最高流速峰值(Vmax)、阻力指数(RI)。血管分级，0级：为无血流；Ⅰ级：为少量血流，可见点、棒状血流；Ⅱ级：为中等血流，一个断面上可见1～2条血管，其长度, http://www.100md.com
