How SPECT Differs from MRI, fMRI, and PET. A SPECT scan is similar to an MRI study in that both can show 3D images of the brain. However, whereas MRI shows the physical anatomy or structure of the brain, SPECT shows how the brain works. PET, another nuclear imaging technique, is similar to SPECT but is a more costly imagining technique.An fMRI scan is usually performed on an outpatient basis. This means you will come into the hospital for the scan and leave afterward. During the test you may wear a hospital gown or your own clothes, but you can't bring anything metal (zippers, clips, pins, glasses) into the room, because it could interfere with the MRI machine. During the test, you lie on a table.What is fMRI? MRI: MRI, or magnetic resonance imaging is a way to see inside the body in order to get a clear picture of anatomy.

FMRI can be used to produce activation maps showing which ...

An fMRI scan starts by taking images of the brain at rest. Those are called baseline images. The next step is to look at the brain while a person is doing something.

It uses the magnetic field of the scanner to affect the ...Resting-state fMRI was first described by Biswal et al in 1995 and has since then been widely used in both healthy subjects and patients with various neurologic, neurosurgical, and psychiatric disorders. As opposed to paradigm- or task-based functional MR imaging, resting-state fMRI does not require subjects to perform any specific task.This is known as a region of interest (ROI) analysis. A general name for an analysis in which you choose to analyze a region selected before you look at whole-brain results is called a confirmatory analysis. Whole-brain maps can hide important details about the effects that we’re studying. We may find a significant effect of incongruent ... Yes, you will need a prescription or referral from a doctor to get an MRI.
