DCE-MRI analysis. A: Heuristic TIC from a point of interest in the popliteal artery (x-axis: time (s); y-axis: relative signal intensity (baseline = 1.0)). IRW: initial rate of washout; AUC: area under the curve; Tonset: time (in seconds) to onset of contrast-enhancement; Twashout: time (in seconds) to washout of contrast. B: Assignment and colour-coding of the voxels within the ROI drawn around the synovium in the suprapatellar recess based on the shape of the TIC (no colour = no enhancement). Plateau (green) and washout (red) represent the most perfused patterns/voxels. C–F: Parametric maps. Brighter colours indicate higher values. ROI drawn around the synovium in the suprapatellar recess (C: no map; D: IRE map; E: ME map; F: Ktrans map).
