Normal synovial vascularity of joints of patients with hemophilic arthropathy on color Doppler ultrasound. a Thirteen-year old boy with severe hemophilia A and a history of recurrent bleeding into his right knee. Color Doppler sonogram obtained on the sagittal anterior central plane at the L1 level shows no color pixel dot within the color box. Score is 0. Objective area of pixels is 0, score equals 0. b Fourteen-year old boy with severe hemophilia A and a history of recurrent bleeding into his right knee. Color Doppler sonogram obtained on the axial anterior-lateral plane at the L3 level shows 2  color pixel dots (less than 4 dots) within the color box, Score equals 0. The area of color pixels within the color box is 569 units2
