Clinical validation of quantitative UTE MRI techniques in musculoskeletal studies remains limited, despite their potential to unveil short T2* information. As these techniques require considerably more scan time than conventional imaging, there is a need for integration of acceleration methods. This study investigated the use of the UTE Spiral VIBE sequence with in-plane acceleration and SPIRiT reconstruction for short T2* mapping of knee structures. As similar image quality and T2* values were obtained for the non-accelerated and accelerated acquisitions, the UTE Spiral VIBE technique shows great promise for fast UTE T2* MRI of the knee.
