title: The relationship between radiographic findings and asymmetrical radioactivity in the shoulder.
abstract: A prospective study was performed to compare asymmetrical radioactivity in the shoulder on 99mTc bone scans with the conventional radiographic findings of 100 right-handed and 8 left-handed patients. Of the 100 right-handed patients, 30 had increased radioactivity in the right shoulder; 5 showed increased radioactivity on the left. Clinical history, shoulder physical examination, and site of injection did not influence the frequency of asymmetrical radioactivity; only dominant handedness correlated with this finding.
