Retrospective Analysis of Indication of Bone Scintigraphy Performed in Our Clinic

Aim: Bone scintigraphy is one of the commonly used radionuclide imaging and it is successfully used in the diagnosis and follow-up of many diseases. The aim of this study is to determine the indications and filming protocols of bone scintigraphy which was performed in our clinic. Material and Method: Two hundred and fifty two patients (132 male, 120 female) who was performed bone scintigprapy in our clinic between December 2011 and June 2013 included the study. Mean age was 50.1±20.2 years. Scintigraphic protocols were made in two ways as late static whole body imaging and three-phase bone scintigraphy according to the type of the diseases. Indications of scintigraphies and scintigraphic protocols were detected. Results: Bone scintigraphy was performed for diagnosis and monitoring of metastatic bone disease to 102 patients (40,5 %), for orthopedic applications to 57 patients (22,6 %), for diagnosis and monitoring of primary bone tumors to 29 patients (11,5 %), for diagnosis of osteomyelitis to 17 patients (6,7 %), for differential diagnosis of infection and loosening of the prosthesis to 12 patients (4,8 %), investigate the viability of the graft in 14 patients (4,6 %), for rheumatologic diseases to 9 patients (3,6 %), for investigate the pathological vertebral fractures and osteoporosis to 4 patients (1,6 %), for diagnosis the metabolic bone disease to 2 patients (0,8 %), for diagnosis of otitis externa to 5 patients (1,98 %) and for for suspicion of malignancy to 1 patient (0,4 %). Late static whole body imaging protocol was applied to 136 patients (54 %) and three-phase imaging protocol was applied to 116 patients (46 %). Discussion: The most common use of bone scintigraphy is the diagnosis and follow-up of metastatic bone disease. It is followed by reasons such as orthopedic applications, monitoring and diagnosis of primary bone tumors and diagnosis of osteomyelitis
