  • 摘要:
      目的  探讨超声助力式弹性成像联合声触诊组织成像量化技术对浅表软组织肿物的诊断价值。
      方法  选取120例浅表软组织肿物患者(共154个肿物)作为研究对象，肿物经活检或手术病理证实为良性122个、恶性32个。以病理结果为基础，比较单独应用超声助力式弹性成像技术、声触诊组织成像量化技术和两者联用对浅表软组织肿物的诊断效能。
      结果  154个浅表软组织肿物中，超声助力式弹性成像技术检出良性肿物107个、恶性肿物20个，诊断灵敏度为62.50%, 特异度为87.70%, 阳性预测值57.14%, 阴性预测值89.92%, 准确度为82.47%; 声触诊组织成像量化技术共检出良性肿物110个、恶性肿物24个，诊断灵敏度为75.00%, 特异度为90.16%, 阳性预测值为66.67%, 阴性预测值为93.22%, 准确度为87.01%; 超声助力式弹性成像联合声触诊组织成像量化技术共检出良性肿物117个、恶性肿物30个，诊断灵敏度为93.75%, 特异度为95.90%, 阳性预测值为85.71%, 阴性预测值为98.32%, 准确度为95.45%。超声助力式弹性成像、声触诊组织成像量化技术联合应用对浅表软组织肿物的诊断效能高于两者单独应用，差异有统计学意义(P < 0.05)。
      结论  超声助力式弹性成像联合声触诊组织成像量化技术对浅表组织肿物具有较高的诊断效能，可作为临床诊断浅表软组织肿物的有效手段，为该病的治疗提供准确的参考依据。

     

    Abstract:
      Objective  To investigate the diagnostic value of ultrasound assisted elastic imaging combined with acoustic palpation tissue imaging quantification technique in superficial soft tissue mass.
      Methods  A total of 120 patients with superficial soft-tissue masses (154 masses) were selected as study subjects, and 122 tumors were confirmed to be benign and 32 malignant by biopsy or surgical pathology. Based on the pathological results, the diagnostic efficacy of ultrasound-assisted elastography alone, acoustic palpation tissue imaging quantification aloneand their combination for superficial soft tissue masses were observed and compared.
      Results  Among 154 superficial soft tissue masses, 107 benign and 20 malignant tumors were detected by ultrasound assisted elastography, with diagnostic sensitivity of 62.50%, specificity of 87.70%, positive predictive value of 57.14%, negative predictive value of 89.92%, accuracy of 82.47%. A total of 110 benign and 24 malignant tumors were detected by acoustic palpation tissue imaging, with diagnostic sensitivity of 75.00%, specificity of 90.16%, positive predictive value of 66.67%, negative predictive value of 93.22%, and accuracy of 87.01%. A total of 117 benign and 30 malignant tumors were detected by ultrasound assisted elastography combined with acoustic palpation tissue imaging quantitative technology, with diagnostic sensitivity of 93.75%, specificity of 95.90%, positive predictive value of 85.71%, negative predictive value of 98.32%, and accuracy of 95.45%. The combined application of ultrasound assisted elastography and acoustic palpation tissue imaging quantitative techniques had higher diagnostic efficacy for superficial soft tissue masses than their application alone (P < 0.05).
      Conclusion  Ultrasound-assisted elastography combined with acoustic palpation tissue imaging has a high diagnostic efficiency in diagnosing superficial tissue mass, which can be used as an effective method for clinical diagnosis of superficial soft tissue mass and provides an accurate surport for treatment of this disease.
