Question

What is the basic difference between mri and fmri imaging techniques? mri is less invasive mri carries less risk to the patient fmri provides less detail fmri allows for real-time observations of changes in brain activity neither shows soft tissue structures of the brain?

Answer 1

Answer:

The basic difference between MRI and fMRI imaging techniques is that MRI provides less detail  

Explanation:

MRI stand for magnetic Resonance Imaging and fMRI stand for Functional Magnetic Resonance Imaging. FMRI is more efficient as they detect those abnormalities in the brain that can not be detected by any other imaging techniques. They even measure the slightest changes in the blood flows and blood oxygen level during any activities by the brain.  

MRI machines are used for imaging the structure of brain. fMRI is costlier than MRI.

Answer 2

The basic difference between an MRI and an FMRI is the fact that an FMRI allows for real-time observations of changes in brain activity by creating images of brain activity, whereas an MRI does not does not increase blood flow to detect such activities as they are happening.
