Abstract

Positron emission tomographic study (PET study) using 15O labeled gases was carried out in 108 patients with cerebrovascular diseases, tumor, cardiac diseases and others to evaluate the clinical usefulness of 15O labeled gas PET study.
The side-effect of 15O labeled gas was not odserbed in any cases, and 15O labeled gas PET study was judged to be highly safe technique.
Quantitative information with 15O labeled gas PET study was judged to be useful clinically in 94-96% of the cases. In comparison with other radionuclide images, X-ray CT and MRI, the information with 15O labeled gas PET study was tended to be superior or more useful to that with other imaging technique in 81% of cases.
15O labeled gas PET study was judged to be useful in 99% of the cases. It is concluded that 15O labeled gas PET study is a useful technique for quantitative measurement of regional tissue metabolism.
