摘　　要：目的　探讨能量多普勒显像 (PDI)对软组织实性肿块的诊断价值。方法　应用CDFI、PDI技术检查 45例软组织实性肿块病人 ,分析CDFI、PDI血流检出率及血流信号分级。结果　 45例软组织实性肿块中良性肿块 2 4例 ,恶性肿瘤为 2 1例 ,PDI血流检出率高于CDFI ,P <0 0 1 ;以血流信号Ⅱ～Ⅲ级判断为恶性肿瘤 ,0～Ⅰ级判断为良性肿块 ,PDI、CDFI对良恶性肿瘤鉴别均有统计学意义。且PDI假阴性为 0 ,CDFI假阴性为 1 9 0 %。结论　PDI血流敏感性高于CDFI。Objective To discuss the value of diagnosing the soft tissue masses by Doppler Power Imaging. Methods CDFI and DPI were performed in 45 cases of tissue masses in order to analize the blood flow detection rates of CDFI and PDI and the degree of blood flow signals. Results Of these 45 cases,24 cases are benign masses,and 21 cases are malignant.The blood flow detection rate of PDI is higher than that of CDFI( P< 0 01).Malignant tumor is decided by the blood flow signal degree Ⅱ to Ⅲ and the benign is degree 0 to Ⅰ.PDI and CDFI are significant in statistic in deferentiating both the benign and the malignant tumors.The false negative rate of PDI is 0,and that of CDFI is 19 0%. Conclusion PDI is more detective than CDFI.It is more benefit to distinguish the benign and malignant tumors in soft tissue. [
