Figure 4

Synovial vascular area predicts Doppler signal within the knee joint. (A) Qualitative Doppler assessment (PQuant) correlates with synovial vascular density within the supra-patella pouch (Spearman r 0.73). (B) PQuant correlates with blood vessel density (Spearman r 0.42). (C) Thresholded Doppler signal for high intensity signal (PDHi) correlates with medium-sized vessel vascular area (Spearman r 0.56).
