Abstract：Objective To investigate the effectiveness of application of high-frequency color Doppler ultrasound in differential diagnosis of soft tissue mass on the body surface. Methods Taken the pathological results as the gold standard, the ultrasonographic imaging features of 252 pathologically-confirmed soft tissue masses on the body surface were retrospectively analyzed, to record the sensitivity, specificity, accuracy, positive and negative prediction values of color Doppler ultrasound. Additionally, the test indexes such as flow classification, PSV (Peak Systolic Velocity), RI (Resistance Indexes) of masses were also analyzed. Results The sensitivity, specificity, accuracy, positive and negative prediction values diagnosed by color ultrasound imaging were 60.00% (21/35), 96.77% (210/217), 91.67% (231/252), 75.00% (21/28) and 93.75% (210/224), respectively. While, the PSV and RI of benign and malignant masses were PSV<20 cm/s and RI<0.7 versus PSV>20 cm/s and RI>0.7. The PSV and RI of Benign Group were lower than those of Malignant Group with statistically significant differences (P<0.05). Conclusion High-frequency color Doppler ultrasound proved its effectiveness in differential diagnosis of soft tissue masses on the body surface, which could be deemed as a first-choice inspection method for soft tissue masses on the body surface.
