Brain imaging techniques are a form of medical imaging which uses various technologies to produce pictures of the brain. There are many different types, each with its own strengths and weaknesses. One technique that does not collect information about brain functioning is computed tomography (CT). CT can take cross-sectional images but it cannot create 3D renderings like magnetic resonance imaging (MRI) or positron emission tomography (PET), which means it cannot see inside your head.

With PET, radioactive particles attached to glucose molecules in your body enter into tissues when you consume food containing sugar or drink something sweetened with a non-nutritive sweetener such as saccharin. These particles emit gamma rays during nuclear decay which can be measured by detectors placed around the body.

which of the following imaging techniques does not collect information about brain functioning? CT scans, MRIs, and PETS are all different types of images that can be used to see inside your head in more detail than a standard eye exam with an ophthalmologist or optometrist. One type that cannot show what is happening inside our heads is computed tomography (CT). With this technique, cross-sectional slices through the patient’s head can be obtained from multiple directions (axial sections) but it cannot create three-dimensional renderings like magnetic resonance imaging (MRI) or positron emission tomography (PET), which means it cannot see around corners on the surface of our brains.

With PET scanning, a small amount of radioactive material that emits positrons is injected into the patient’s bloodstream. The blood then carries this substance to the brain, where it concentrates and remains for about 20 minutes before being broken down by other parts of our body. After sufficient time has elapsed, a scanner records which areas have been activated

With this technique, cross-sectional slices through the patient’s head are taken from different directions and then assembled to form a three-dimensional image.

CT scans, MRIs, and PETS are all different types of images that can be used to see inside your head in more detail than a standard eye exam with an ophthalmologist or optometrist. One type that cannot show what is happening inside our heads is computed tomography (CT). With this technique, cross-sectional slices through the patient’s head are taken from different directions and then assembled to form a three-dimensional image.

CT scans can be used for many things such as finding out if you have broken your arm before it becomes too hard to see on an x-ray or seeing how much plaque has built up in your arteries which could lead to heart disease. These images provide doctors with detailed views into the organ being studied without having them cut open humans to study.

CT scans are very useful for diagnosing various health problems and conditions, but they do not provide information about brain functioning which is what EEGs measure.

EEGs (electroencephalography) use electrodes on the head to record an electro-magnetic pattern that can be used by doctors or researchers to understand how your brain is working. You may also know them as “brain waves” because these patterns look like a wave moving from front to back of the person’s head when we see it read out in numbers – even though this technique doesn’t actually measure brainwaves!

The most common type of MRI images are called T scans and show structures inside our bodies based on their ability to absorb radio signals from different angles. What it does not show is brain functioning – which other techniques, like EEGs and PET scans do.

MRI images are often used to diagnose cancerous tumors because they can highlight them with their higher density than surrounding tissue. We also use MRI for strokes to look at how blood flow through the brain has been interrupted by a clot or torn artery, injuring different areas of the brain in order to help plan treatment.

PET scans work similarly to MRIs but instead pick up glucose (sugar) that’s being metabolized by cells into an energy source called ATP rather than radio waves which just bounce off tissues without getting absorbed based on differences in their densities.
