多普勒成像联合高频超声在体表软组织肿块中的诊断价值

Diagnostic Value of Doppler Imaging Combined with High Frequency Ultrasound in Surface Soft Tissue Masses

目的:探讨多普勒成像联合高频超声在体表软组织肿块定性诊断中的价值。方法:选取2017年3月至2018年3月在我院经病理检查确诊的97例体表软组织肿块患者临床资料,均行多普勒成像联合高频超声定性诊断,观察良恶性肿块诊断情况及超声表现,比较良恶性血流分级情况。结果:97例患者经高频多普勒超声共检出90例,诊断符合率为92.78%(90/97),其中良性85例、恶性5例;漏诊率为7.23%(7/97)。在CDFI血流分级中,良性肿块以0级、Ⅰ级血流分布为主,恶性肿块则以Ⅱ～Ⅳ级血流分布为主,良性肿块0级、Ⅰ级的比例91.30%、6.52%比恶性肿块多,且Ⅲ级、Ⅳ级的比例1.09%、0.00%比恶性肿块少(P <0.01),且PSV(16.71±2.97) cm/s、RI(63.11±12.12)%均比恶性肿块低(P<0.01)。结论:体表软组织肿块应用多普勒成像联合高频超声定性诊断的临床价值显著,能清晰显示肿块内部超声特征,帮助肿块类型判断,且肿块良恶性鉴别诊断的符合率高,可作为定性诊断的首选。

Objective: To explore the diagnostic value of doppler imaging combined with high frequency ultrasound in soft tissue mass on the surface of body. Methods: 97 patients with soft tissue mass on the surface of body who had pathological diagnosis were enrolled to this study from March 2017 to March 2018. The soft tissue mass were evaluated by doppler imaging combined with high frequency ultrasound,meanwhile,the blood flow classification were compared between benign and malignant. Results: A total of 90 cases were detected by high frequency Doppler ultrasound in 97 patients. The diagnostic coincidence rate was 92.78% (90/97),of which 85 cases were benign and 5 cases were malignant,and the missed diagnosis rate was 7.23% (7/97). In CDFI blood flow grading,benign tumors were mainly grade 0 and grade Ⅰ blood flow distribution,while malignant tumors were mainly grade Ⅱ-Ⅳ blood flow distribution. The proportion of benign tumors in grade 0 and grade Ⅰ was 91.30% and 6.52% more than malignant tumors. The proportion of grade Ⅲ and grade Ⅳ tumors was 1.09% and 0.00% less than malignant tumors (P <0.01),and PSV (16.71+2.97) cm/s and RI (63.11+12.12) % were lower than malignant tumors (P <0.01). Conclusion: The clinical value of Doppler imaging combined with high frequency ultrasound in qualitative diagnosis of soft tissue masses on the surface of the body is remarkable. It can clearly show the characteristics of the internal ultrasound of the masses,help to judge the type of the masses,and the coincidence rate of differential diagnosis between benign and malignant masses is high,so it can be used as the first choice for qualitative diagnosis.
