摘要
目的探讨彩色多普勒超声对浅表组织肿块良恶性的鉴别诊断价值。方法采用回顾性研究的方法,对我院收治的经彩色多普勒超声证实的100例浅表组织肿块进行声像图分析,并与手术和术后病理结果比较,比较浅表组织肿块良性和恶性的声像图特点和血流信号。结果 100例浅表组织肿块中共有80例为良性病变:肿块长轴与皮肤平行,平均圆度系数为2.58,与术后病理诊断符合率为93.8%;有20例为恶性肿块:平均圆度系数为1.51,诊断符合率为70.0%。良性与恶性肿块的圆度系数以及后方回声衰减经统计学检验表明二者差异有显著性(P<0.05),而良性与恶性肿块的内部回声、边界等二维征象方面差异无统计学意义(P>0.05)。彩色多普勒超声结果表明:100例软组织肿块中66例有血流信号,良性肿块收缩期峰值流速不高于20cm/s,阻力系数低于0.70,与术后病理结果的诊断符合率分别为91.7%和86.1%,可作为良性和恶性肿块鉴别的临界值(P<0.05),其特异性和敏感度分别为87.7%和83.0%。结论彩色多普勒超声在浅表组织肿块良恶性鉴别中具有较高的应用价值,其诊断符合率高,成像清晰,而肿块的圆度系数、后方回声衰减、收缩期峰值流速和阻力系数均可作为良恶性肿块鉴别依据。
Objective To explore the clinical value of color Doppler uhrasonography in differential diagnosis of be-nignand malignant superficial tissue masses.Methods Witha retrospective analysis method,to analyze sonogram of 100 patients of superficial tissue massconfirmedby color Doppler ultrasound compared with surgical and pathologic results. and compare sonographic characteristics and flow signals.Results In 100 cases of superficial tissue mass,there were 80 cases of benign lesions with the long axis paralleled to the skinand the average value of roundness index which was 2.58.The diagnose accordance rate was 93.8%;While another 20 cases showed malignant tumors with an average roundness coefficient of 1.51 and diagnose accordance rate of 70.0%.The total diagnose accordance rate was 89.0%, and there was significant difference of roundness index and posterior acoustic attenuation between the two groups（P 〈0.05）,but there was no significantdifference between the internal echo mass,borders（P〉0.05）.Color Doppler ultra-sound results showed that 66 of 100 cases had blood flow signals,and the critical value ofbenign and malignant messes identify was peak systolic velocity（PSV）≤20 cm/s and resistance index（RI）〈0.70,thesensitivity and specificity were 87.7% and 83.0%,respectively.Conclusion Color Doppler ultrasound has a high value in superficial benign and ma-lignant tissue mass,and the value of roundness index,posterior echo attenuation peak systolic velocity and drag coeffi-cient can be used as basis for the identification of benign and malignant tumors.
