In order to create quantitative functional images of metabolism, blood flow, receptor binding, etc. using brain PET, it is essential to estimate the input function that represent the distribution of PET tracers to the brain by arterial blood sampling. Since arterial blood sampling is invasive, a method of estimating radioactivity in arterial blood from PET images has been proposed as an alternative method, and many studies have already been conducted. However, the accuracy of the estimation of the input function by the image was insufficient due to the restrictions of spatial resolution and sensitivity. Semiconductor PET-CT is characterized by high sensitivity and high resolution. The purpose of this study is to develop a non-invasive input function estimation method using semiconductor PET-CT and clarify its accuracy.
Pharmacokinetics
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.
