fMRI (functional magnetic resonance imaging) is a non-invasive brain imaging technique in which an individual lies in an MRI machine. The MRI machine has a magnetic field and a gradient coil which causes changes in the alignment of water molecules in the brain. The idea is that when a region is active it requires more oxygen, and thus seeing an increased amount of aligned molecules suggests that that particular region might be involved in a specific task.

PET (positron emission tomography) is an invasive brain imaging technique which involves injecting an individual with radioactive glucose and measuring the amount of glucose in different brain regions. Similar to a region needing oxygen, a highly active region also needs glucose for its metabolic processes. If during a specific task a particular brain region were active, one would expect to see more signal from that brain region while being monitored by a PET scan.

What specific date was the PET scan invented?

Invented by Proffesor Michael Anthony Principe and his accomplish Kosta Kolaj in 1983 and suitable for humans in 1996.


What are different types of neurophysiological technique?

Some examples of neurophysiological techniques include electroencephalography (EEG), magnetoencephalography (MEG), functional magnetic resonance imaging (fMRI), positron emission tomography (PET), and transcranial magnetic stimulation (TMS). Each method offers unique insights into brain activity and connectivity.


Positron-emission tomography forms images of body tissues this is known as what?

Positron-emission tomography (PET) forms images of body tissues using radioactive tracers that emit positrons. This imaging technique is used to detect functional processes in the body, such as metabolism or blood flow, and is commonly used in medical diagnosis and research.


PET scan?

A PET scan (positron emission tomography) is a type of imaging test that uses radioactive tracers to detect changes in metabolism and organ function. It is commonly used in cancer diagnosis and treatment planning, as well as in neurology to study brain activity. The images produced by a PET scan can help doctors identify tumors, evaluate response to treatment, and assess various diseases.


What are the benefits of using a cool pet pad, such as a self-cooling pet pad, for keeping your pet comfortable during hot weather?

Using a cool pet pad, like a self-cooling pet pad, can help keep your pet comfortable in hot weather by providing a cool surface for them to rest on. This can help prevent overheating and dehydration, especially for pets with thick fur or those who are more sensitive to heat. Cool pet pads can also help soothe sore muscles and joints, making them a great option for older pets or those with arthritis.

What is the scan that allows one to observe blood flow or metabolism in any part of the brain?

A positron emission tomography (PET) scan can be used to observe brain metabolism by detecting levels of glucose consumption. Alternatively, a functional magnetic resonance imaging (fMRI) scan can show blood flow changes associated with brain activity.


What is the difference between a micro pet and a normal pet?

the difference between a micro pet and a normal pet is that a micro pet is a really small animal such as a micro pig and a normal animal is a animal just like a normal person normal size normal wight and that is the difference between a normal animal and a micro animal.

What advantage does the MRI scan have over the Pet scan for the subject?

A PET scan shows what level / stage (if any) the cancer is at. An MRI scan doesn't do this, the reader, looks for abnormalities on the scan which shows up everything in the body.


What IS the difference between cat and pet scan?

The difference is in the type of radiation used to form the image. A Computed Axial Tomography (CAT) scan can use any type of radiation to create the image, the specific type is not specified in the name, but most often uses X-rays; but a Positron Emission Tomography (PET) scan specifically uses positrons as the radiation form. A third type, Magnetic Resonance Imaging (MRI) uses the miniscule magnetic fields of naturally occurring compounds within the human body to create its images.
