IVIM MRI of juvenile idiopathic arthritis
in the knee can be performed reliably with as few as 5 b-values,
while attention has to be paid to a high enough b-value threshold
during fitting of diffusion and perfusion values.
Figure 1: Diffusion coefficients (A) and perfusion
fraction (B) for effusion, synovial membrane and muscle tissue
calculated with 12 different b combinations and 4 b-thresholds
Figure 2: Relative difference of the calculated
diffusion (A) and perfusion fraction (B) values between b-value
combination #1 and all other b-combinations.
