Images of bone scintigraphy, positron emission tomography-computed tomography (PET-CT), HR-pQCT and Magnetic Resonance Imaging. (MRI) in one representative treatment-naïve ECD patients (LJ008). a Bone scintigraphy showed bilateral symmetric uptake at the distal tibial region. b PET-CT showed abnormal uptake at the same tibial region. c HR-pQCT revealed localized structural alteration of trabeculae network in right tibia. d Cross-sectional view of PET-CT showed increase of uptake in tibia, where bone lesions existed, reaching a SUV maximum of 5. e and f MRI of affected left ankle showed localized heterogeneous low T1- and T2-signal, resembling that of cortex
