Figure 9From: Standardized volumetric 3D-analysis of SPECT/CT imaging in orthopaedics: overcoming the limitations of qualitative 2D analysis SPECT uptake region analysis. Using a higher threshold (four times the mean of the reference region) showed a higher value for patient 2's uptake region (bottom figure, upper patellar pole) as compared to patient 1, (top figure, lower patellar pole).Back to article page
