Functional MRI is an MRI procedure to determine activation in the brain during activities or in disease condition. Also known as fMRI. fMRI uses the same MRI machine as other examinations but it requires special additional software. Detection of activation in the brain is determined by the oxygen content in the blood vessel under the premise that oxygen level is high when the brain is activated.

Functional MRI scans can track changes this?
the answer for the crossword puzzle is origin
What factor is least likely to affect the results and interpretation of a functional MRI?
cancerous growth
What can one do during an mri?
It depends on the scan, and your age. For an fMRI or Functional MRI exam, the patient is asked to perform a wide variety of tasks, like playing games. If a child is to be scanned, they are usually sedated, so therefore cannot play any games whatsoever.
Do you say an MRI or a MRI?
an MRI
Do you say a MRI or an MRI?

Will brain MRI show blood flow?
A brain MRI (Magnetic Resonance Imaging) primarily provides detailed images of brain structures and tissues, but it does not directly show blood flow. However, specialized MRI techniques such as functional MRI (fMRI) and MR angiography (MRA) can assess blood flow and vascular conditions. fMRI measures changes in blood oxygenation levels, which correlate with neural activity, while MRA visualizes blood vessels.
What is functional magnetism?
Functional magnetism refers to the use of magnetic resonance imaging (MRI) techniques to measure brain activity by detecting changes in blood flow. This method enables researchers to study brain function and connectivity in response to various tasks or stimuli.
Where can you get a digital motion x ray in Australia?
I am also looking for a dmx and the only thing i can find is functional mri. If you find one could u put the address up here.
What Mri detects?
MRI, or magnetic resonance imaging, primarily detects soft tissue structures in the body, making it particularly useful for visualizing the brain, spinal cord, muscles, ligaments, and organs. It provides detailed images that can reveal abnormalities such as tumors, inflammation, and degenerative diseases. Unlike X-rays and CT scans, MRI does not use ionizing radiation, making it a safer option for many patients. Additionally, functional MRI (fMRI) can assess brain activity by measuring changes in blood flow.
Will my head be out of the MRI for an MRI of my tibia?
If the MRI technologist positions you with your leg going into the magnet (the MRI machine) then your head would be out of it. Call the facility where you are scheduled to have the MRI and ask to speak with the MRI technologist and they can fully explain to you exactly how you will be positioned.
What does a functional mri show?
Functional MRI (fMRI) measures brain activity by detecting changes in blood flow and oxygenation levels. When a specific brain region is more active, it consumes more oxygen, leading to increased blood flow to that area, which fMRI can visualize. This technique allows researchers to identify which parts of the brain are involved in various tasks, such as thinking, feeling, or moving. It is widely used in both clinical settings and research to study brain function and connectivity.
O2 gas in MRI?
In MRI (Magnetic Resonance Imaging), O2 gas is not directly imaged like tissues or organs. However, it plays a crucial role in certain applications, such as functional MRI (fMRI), where changes in blood oxygen levels are used to infer brain activity. The presence of oxygen can influence the magnetic properties of blood and enhance the contrast in images. Additionally, oxygenation levels can provide insights into various physiological processes and conditions.
