All

Inclusion criteria

Inclusion criteria: Patients who undergo O-15 gas PET as a clinical examination

Exclusion criteria

Exclusion criteria: under-aged, those who lack the ability to give informed consent, or those with severe anemia (less than 10g/dl for men, less than 9g/dl for women)

Design outcomes

Primary

Measure	Time frame
For patients undergoing O-15 gas PET of the brain as an insurance coverage test, blood will be collected from the A line, and at the same time, PET images of blood vessels in the neck and chest will be acquired. The accuracy of the non-invasive input function estimation method is evaluated by comparing the radioactivity data obtained from arterial blood and images.	—
