Fig. 5From: Influence of the anterior notch in mobile-bearing UKA on patellofemoral radiotracer uptake and clinical outcomeIn transverse planes of the SPECT-CT fusion images regions of interests (ROIs) were defined manually. Here this process is shown for the medial facet of the patella. Many ROIs then comprised a volume of interest (VOI). Within the VOI the maximum tracer uptake was determinedBack to article page
