Abstract：Objective To investigate the key points of color Doppler flow imaging (CDFI) in differential diagnosis of calf muscular venous thrombosis and intramuscular hematoma in human legs. Methods The imaging characteristics of two di-mensional ultrasonography and CDFI findings in 54 patients with calf muscular venous thrombosis in leg (thrombosis group) and 24 patients with intramuscular hematoma in legs (hematoma group) were retrospectively analyzed, and key points of ultra-sonic differential diagnosis were summarized. Results The imaging characteristics of the two dimensional ultrasonography and CDFI findings in the two groups were similar. The hypoechoic was found in 36 patients in thrombosis group and 12 patients in hematoma group; strip-shaped echo was found in 37 patients in thrombosis group and 8 patients in hematoma group; no local blood flow signal was found in 30 patients in thrombosis group and 24 patients in hematoma group; positive results of compres-sion test were found in 40 patients in thrombosis group and 16 patients in hematoma group. Thrombosis extended along the blood vessels in thrombosis group, while hematomas in hematomas group was mainly localized; the end of thrombosis connect-ed with veins while hematoma did not show the sign, in which only 10 patients in hematoma group compressed nearby veins. Conclusion Ultrasound imagings of calf muscular venous thrombosis and intramuscular hematoma in legs may be confused, and CDFI can be used as an important method for differential diagnosis.
