ABSTRACT
Bone scintigraphy is the most frequent examination among various diagnostic nuclear medicine procedures. According to an UNSCEAR (2008) report, which included the results of a comprehensive survey of radiology practice worldwide, bone scintigraphy accounted for 33.6% of all diagnostic nuclear medicine procedures for the period 1997-2007 in the specic country group of health care level I in which a country has more than 1 physician per 1000 population (Figure 19.1). Bone scans are commonly used for the imaging of new bone formation that may occur due to the presence of almost any skeletal pathology and for demonstrating increased and/or decreased gamma ray emissions localized to the site of bone abnormalities by use of the radioisotope of technetium-99m methylene diphosphonate (MDP) hydroxymethane diphosphonate (HDP). us, the bone scan has been applied as an initial procedure for
identifying several disorders such as skeletal metastases, osteosarcoma, osteomyelitis, and nondisplaced fractures. In addition, bone scans are often repeated regularly for the same patient who requires monitoring for identifying several disorders such as skeletal metastases, primary bone tumors, and osteomyelitis.
