Multi-component T2* relaxations have been observed in human knee cartilages with ultrashort echo time (UTE) acquisitions (min TE=0.6ms), which have potential to reflect disorganization of collagen fibers in early-stage degenerative cartilages. This work demonstrates the repeatability of in vivo multi-component T2* mapping via healthy subject scans on a 3T MRI scanner.
