Fig. 1

A 47-year-old man with histopathologically confirmed dedifferentiated chondrosarcoma in thigh showed a well-encapsulated mass with irregular peripheral enhancement. By DCE imaging, several ROIs drawn in the most enhanced and hyperperfused region in axial post-contrast T1WI (A) and color map (B) showed parameters as follows, Ktrans 0.350 min−1, Kep 0.438 min−1, Ve 0.844 and TIC type 5 (C). DCE, dynamic contrast-enhanced; Kep, microvascular permeability reflux constant; Ktrans, volume transfer constant; ROI, region of interest; TIC, time intensity curve Ve, volume extravascular-extracellular space per unit tissue volume
