ACL graft healing by combined PET/MR imaging is readily feasible but has
limited quantitative accuracy with use of conventional PET systems. The
application of next generation digital photon counting in PET improves the
quantitative accuracy and precision of assessment of graft metabolic activity.
This advanced imaging modality also holds potential for ultra-low dose PET
imaging, enhancing the clinical utility of such a combined imaging approach for
detailed assessment of ACL graft viability after reconstructive surgery.
