RT Journal Article SR Electronic T1 Significance of Photon-Deficient Areas in Radionuclide Bone Scans JF Journal of Nuclear Medicine Technology JO J. Nucl. Med. Technol. FD Society of Nuclear Medicine SP 208 OP 210 VO 8 IS 4 A1 Gupta, Shiv M. A1 Panduranga, Anantapur A1 Buckley, Margaret A1 Crucitti, Thomas W. A1 Herrera, Nilo E. YR 1980 UL http://tech.snmjournals.org/content/8/4/208.abstract AB Photon-deficient areas were observed in 64 out of 884 (7.2%) bone scans performed in a general hospital over a period of 1 yr. The intrinsic causes constituted about 80% of the “cold” lesions seen; whereas extrinsic causes were responsible for the remaining 20%. Orthopedic implants were the most common source of artifactual cold lesions. The value of special views during bone scanning and care during interpretation is suggested.
