In this GE Healthcare right proximal femur scan, the right greater trochanter is incompletely scanned.
Case Description:
In this GE Healthcare right hip scan, a portion of the greater trochanter is cut off. This will affect the result of the total hip. Notice that the femoral neck is placed differently in GE Healthcare than Hologic.
