title: Evaluation in femoral neck fracture scintimetry: modes of region of interest selection and influence on results.
abstract: Different sized ROIs within the femoral head and different modes of calculation were used in [99mTc]MDP scintimetry after femoral neck fracture. In preoperative scintimetry, correction for increased trochanteric uptake gave the best discrimination, whereas in postoperative scintimetry the direct ratio fractured/intact femoral head was superior. The change in ROI size had little influence.
