Abstract

Using a newly developed whole body gamma scanner (Toshiba-RDA-601), we recorded the whole body bone scans in 5 patients (two normal, osteomalacia, bone metastases of prostate cancer and bone metastases of breast cancer), and compared the regular scintiscans with those of bird's-eye view images which were made with the data processor of the scanner.
The scans were started about 2 hours after intravenous injection of 3 to 8 mCi of 99mTC-monofluorophosphate stannous fluoride.
The recorded bird's-eye view scans displayed the skeletal system vividly as they were, and the distribution of radioactivity semiquantitatively.
In conclusion the bird's-eye view scan is superior to the regular scan, in view of the point that it expresses the distribution of radioactivity semiquantitatively and enables us to know the amount of abnormally accumulated radioactivities by measuring the height of the peak of the diseased area, although this is very difficult in the regular scan.
But at present we need more clinical studies in order to determine which is better in detecting abnormal part clinically.
