【摘要】 目的:比较光散射成像(diffused optical tomography,DOT)与彩色多普勒血流显像(color doppler flow imaging,CDFI)在乳腺占位性病变鉴别诊断中的应用价值。方法:对79例,85个乳腺占位性病灶术前分别行CDFI和超声DOT检查,以手术病理为金标准,对比分析CDFI和超声DOT对乳腺肿块良恶性的诊断结果。结果:DOT诊断乳腺恶性病灶的敏感度92.1%,特异度87.2%,准确度89.4%,CDFI诊断乳腺恶性病灶的敏感度73.6%,特异度76.6%,准确度75.3%;脉冲多普勒中根据血流的阻力指数(resis-tance index,RI)诊断乳腺恶性病灶的敏感度57.9%,特异度85.1%,准确度72.9%。联合CDFI和脉冲多普勒诊断乳腺恶性病灶的敏感度为55.2%,特异度为89.4%,准确度为71.7%。结论:DOT在鉴别诊断乳腺占位性病变良恶性中的准确度高于CDFI,值得临床推广应用。更多还原

【Abstract】 Objective:To compare the value of diffused optical tomography(DOT)and color doppler flow imaging(CDFI) in the differential diagnosis of breast occupied lesions.Methods:Seventy-nine patients with eighty-five breast lesions were examined by DOT and CDFI.Using surgical pathology as the diagnostic standard,the accuracy of DOT and CDFI were compared in the diagnosis of benign and malignant breast masses.Results:The sensitivity,specificity and accuracy of DOT were 92.1%,87.2% and 89.4%,respectively.The sensitivity,specificity and accuracy of CDFI were 73.6%,76.6% and 75.3%,respectively.The sensitivity,specificity and accuracy of pulsed wave doppler u1trasonography(PW)according to blood flow resistance index(RI)were 57.9%,85.1% and 72.9% respectively.Combined with PW,the sensitivity,specificity and accuracy of CDFI were 55.2%,89.4% and 71.7%,respectively.Conclusion:The accuracy of DOT is higher than that of CDFI,thus it’s a new technique worthy of popularizing.更多还原
