Does obliterative airway disease progress in heterotopic airway allografts without persistent alloimmune stimulus?
OAD progresses despite removal of alloimmunity if the initial period of alloimmune injury is sufficient. Airway epithelial loss correlated with progression to fibroproliferation, suggesting that the epithelium plays a significant role in the pathogenesis of OB.
SPECT/CT findings significantly correlate with the degree and size of chondral lesions on MR images. Grade 3 and 4 chondral lesions of the knee, as well as larger lesions, correlate with a high bone tracer uptake.
