What is perfusion of the brain?
A brain perfusion scan is a type of brain test that shows the amount of blood in certain areas of your brain. This can help show how your brain is functioning. The areas of the brain that are very active often show greater blood supply, oxygen supply, and use of glucose.
Can PET be used for brain?
A brain positron emission tomography (PET) scan is an imaging test that allows doctors to see how your brain is functioning. The scan captures images of the activity of the brain after radioactive “tracers” have been absorbed into the bloodstream. These tracers are “attached” to compounds like glucose (sugar).
What does the pet reveal about the brain?
A brain positron emission tomography (PET) scan is an imaging test of the brain. It uses a radioactive substance called a tracer to look for disease or injury in the brain. A PET scan shows how the brain and its tissues are working.
What does a CT perfusion show?
Computed tomography (CT) perfusion imaging shows which areas of the brain are adequately supplied or perfused with blood and provides detailed information on delivery of blood or blood flow to the brain. CT perfusion scanning is a noninvasive medical test that helps physicians diagnose and treat medical conditions.
How are SPECT and PET used for Brain perfusion?
Single photon emission computed tomography (SPECT) and PET can provide qualitative and quantitative perfusion data. The role of SPECT and PET in the diagnosis of chronic vascular disease, traumatic brain injury (TBI), dementia, and epilepsy is discussed in this chapter.
What are the different types of brain perfusion scans?
This can provide information on how your brain is functioning. There are several different types of brain perfusion scans. Some tests, such as a single photon emission computed tomography (SPECT) or a positron emission (PET) scan, use radiotracers, which are radioactive substances that emit tiny particles.
How does brain positron emission tomography ( PET ) work?
PET measures emissions from radioactively labeled metabolically active chemicals that have been injected into the bloodstream. The emission data from brain PET are computer-processed to produce multi-dimensional images of the distribution of the chemicals throughout the brain.
