【摘要】：目的比较超微血管成像(SMI)两种成像模式[彩色模式超微血管成像(cSMI)和灰阶模式超微血管成像(mSMI)]和CDFI诊断乳腺肿瘤的价值。方法对134例患者的146个乳腺肿块分别行CDFI及SMI检查,对CDFI、cSMI、mSMI图像的血流特点进行分型。比较3种血流检测方法在良恶性乳腺肿瘤诊断中的价值。结果 CDFI和cSMI图像显示乳腺恶性肿瘤的血流较良性肿瘤丰富;mSMI图像中良恶性肿瘤血流类型差异有统计学意义(χ2=88.10,P0.001);CDFI、cSMI、mSMI诊断乳腺恶性肿瘤敏感度分别为74.47%(35/47)、80.85%(38/47)、76.60%(36/47),特异度分别为89.90%(89/99)、86.87%(86/99)、95.96%(95/99),准确率分别为84.93%(124/146)、84.93%(124/146)、89.73%(131/146),三种血流检测方法诊断乳腺恶性肿块的敏感度、准确率差异无统计学意义,CDFI与cSMI、CDFI与mSMI诊断特异度差异无统计学意义,mSMI诊断恶性肿瘤的特异度大于cSMI(χ2=5.212,P=0.022)。结论SMI与CDFI诊断乳腺良恶性肿瘤可相互补充,但SMI可提供更多低速血流信息,SMI的两种成像模式中mSMI较cSMI诊断价值更高。
[Abstract]:Objective to compare the value of two imaging modes (color mode hypermicrovessel imaging (CMI) and gray scale mode hypermicrovessel imaging (mSmi)) and CDFI in the diagnosis of breast tumors. Methods 146 breast masses in 134 patients were examined by CDFI and SMI respectively. The blood flow characteristics of CDFI cSMIM mSMI images were classified. The value of three blood flow detection methods in the diagnosis of benign and malignant breast tumors was compared. Results CDFI and cSMI images showed that the blood flow of malignant breast tumors was more abundant than that of benign tumors. There were statistically significant differences in the blood flow types of malignant tumors (蠂 2 88.10 / P 0.001 / CDFII / cSMImSMI = 74.47 / 35 / 80.85 / 80.85 / 47 / 76.60), and the specificity was 89.90 / 89 / 9986.87 / 86 / 86 / 9999 / 95 / 99, respectively. The accuracy was 84.933c / 12414663 / 84.93n / 84.93P / 124P / 1464 / 14689.73 / 1, respectively, and the sensitivity of the three blood flow methods in diagnosing malignant breast masses was 131146n. There was no significant difference in accuracy between CDFI and cSMI-CDFI and mSMI. The specificity of mSMI in the diagnosis of malignant tumor was higher than that in cSMI (蠂 ~ 2 ~ 2 ~ (5.212P) P ~ (0.022)). Conclusion SMI and CDFI can complement each other in the diagnosis of breast benign and malignant tumor. But SMI can provide more low velocity flow information. MSMI has higher diagnostic value than cSMI in the two imaging modes.
