Figure 5From: Standardized volumetric 3D-analysis of SPECT/CT imaging in orthopaedics: overcoming the limitations of qualitative 2D analysis Non-normalized SPECT renderings. Renderings of the SPECT uptake region for patient 1 (left column) and patient 2 (right column) at 90% maximum SPECT intensity (top row) and 60% maximum SPECT intensity (bottom row). Without a method to identify a clinically relevant threshold intensity, drawing clinical conclusions is problematic.Back to article page
