This analysis evaluates the STAIR-UTE sequence for imaging cortical bone, suggesting high positive contrast across anatomical sites.
Motivation: The short TR adiabatic inversion recovery UTE (STAIR-UTE) sequence allows direct imaging of bone, providing CT-like positive contrast Goal(s): To evaluate the efficacy of 3D STAIR-UTE in imaging bone at different anatomic sites. Approach: This study evaluates the SNR and CNR efficiency of UTE, ZTE and STAIR-UTE for rapid, high-contrast bone imaging across various anatomical sites. Results: STAIR-UTE enables direct imaging of cortical bone with positive contrast, while UTE, and ZTE provide negative contrast for bone across various anatomical sites. Impact: STAIR-UTE allows fast direct imaging of cortical bone at various anatomical sites with high positive contrast, with potential for routine clinical applications
