Criteria for evaluation of pMRI findings according to Tiderius et al. [34]

Enhancement	Description
Normal	Full visualization of the epiphyseal vascular canals and physis
Asymmetric	Either the epiphyseal vascular canals or the physes had reduced intensity compared with the contralateral side or the overall signal intensity of the epiphyseal cartilage was reduced compared with the contralateral side
Focal decrease	Clear area of decreased signal intensity within the epiphysis or the ossification center
Global decrease	Absence of enhancement within the entire epiphysis, including the ossification center if present

pMRI = perfusion MRI.
