Insights of cartilage imaging in cartilage regeneration

Figure 6 18F sodium fluoride (18F-NaF) served as a one-stop modality to assess whole joint, that is, bone pathology, cartilage, and ligaments (sagittal T1 turbo spin echo) showed osteophyte (orange arrow) and sclerosis (yellow arrow) with corresponding 18F-NaF uptake. A and B: Fused positron emission tomography/magnetic resonance imaging (PET/MRI); C: Sagittal three-dimensional MEDIC did not have any structural abnormality but when fused with PET; D: There was high uptake volume of interest (white arrow) termed as “subchondral magic spot”; E and F: Sagittal T2 spectral attenuated inversion recovery depicted grade 1 bone marrow lesion (blue arrow) with corresponding uptake in fused PET/MRI; G: Axial T2* showed degenerated medial and lateral trochlear cartilage (pink arrow); H: Corresponding fused PET/MRI; I: T2 relaxometry with raised values.
