Power Color Doppler and Spectral Doppler Ultrasonography to Evaluate Response to Intra-articular Steroid Injection in Knee Joints in Juvenile Idiopathic Arthritis.

Objective: To evaluate the role of ultrasonographic indices (Color Fraction and Resistive Index) in assessing the effect of intra-articular steroid (IAS) injection on synovial inflammation in knee joints of Juvenile Idiopathic Arthritis (JIA) patients and to determine the correlation between these ultrasonographic indices and clinical and laboratory parameters in JIA patients after IAS.

Methods: Twenty seven patients of JIA and equal number of age and sex matched healthy controls were enrolled. Thirty six knee joints were injected with IAS.
