T2* mapping can detect early iron deposition caused by repeated bleeding in patients with hemophilia and could be used as a sensitive biomarker to detect early cartilage changes and develop preventative treatment plans.
Images from one representative participant (male, 17 years old) with hemophilic arthropathy. Conventional (A) T1WI. (B) PDWI. (C) T2*-anatomical image show relatively complete articular surface (yellow arrow) without damage. (D) T2* mapping shows uneven distribution in the cartilage and the decreases (red arrow) of cartilage T2* value indicate damage.

T2* values of articular cartilage in different regions (mean ± SD)
