Abstract
|
|
|
Recently, the clinical use of radionuclide bone scan has been populized for the detection of bone lesions. For the sensitivity rate of this modality is superior to that of the radiography in the reflexion of local bone pathology.
Especially, bone scanning offers reliable means for establishing the early detection, determining the extent cof the disease and assessing the therapeutic response in bone tumor, infection and trauma.
A comparative study of bone scans to radiographies with 45 proven cases of bone tumors, inflammations land fractures was tried at Department of Radiology, Chung Ang university hospital, during January 1980 to October 1980.
Results were as follows:
1. Increased radioactivities were seen in all of the primary malignant bone tumors, but exostosis and bone Cyst were showed negative finding in bone scans.
2. No evidence of increased uptake was noted in one case of destructive metastatic lesion without osteoblastic reaction.
3. Inflammations of skeletal system were detected by bone scan at earlier time than by orthodox radiograpby. It was difficult to differentiate osteomyelitis from other inflammatory diseases, such as cellulitis or septic arthritis, by bone scan only.
4. Fresh fractures were identified as increased radioactivity, but healed fractures were negative in bone scans. Prolongation of increased uptake was noted in delayed union.
