Serum Angiogenesis Markers and Their Correlation with Ultrasound-Detected Synovitis in Juvenile Idiopathic Arthritis

Figure 1

Ultrasound evaluation of joint vascularization scale using Power-Doppler Ultrasonography imaging. Examples of visualization of different degrees of joints inflammation and angiogenesis. Joint vascularization scale: grade 0 = no signs of vascularization, 1 = mild (presence of single/vessel dots), 2 = moderate (presence of confluent vessel dots in less than half of the synovial area), and 3 = marked (presence of confluent vessel dots in more than half of the synovial area).
