This panel shows incorrect analysis of a Hologic left hip scan. The femoral neck box is not anchored to the greater trochanter and the global region of interest is incorrectly placed.
This is the corrected Hologic left hip analysis.
This figure diagrams the correct placement of the femoral neck box on a Hologic hip scan.
This figure diagrams the correct placement of the global region of interest box in a Hologic hip scan.
Case Description:
In the left panel, there are numerous errors in the analysis of the Hologic hip image. The femoral neck box is not anchored to the greater trochanter. The global hip region of interest box is also not correctly positioned. The right panel shows the corrected analysis. The bottom line in the hip global region of interest is the most important related to analysis (Feit et al. below).
