title: Significance of renewal asymmetry in bone scans: experience in 795 cases.
abstract: A retrospective study of 795 consecutive bone scans employing either 18F or 99mTc-pyrophosphate to evaluate the diagnostic value of renal asymmetry in such scans has been carried out. It is concluded that asymmetric renal images in bone scans convey relatively specific information regarding renal pathology, especially in the 99mTc-pyrophosphate studies.
