ad- small movements do not ruin the scan, pet has been used for many diagnosis of diseases. Dis- Image does not show as clearly as FMRI, expensive.
11 of 21
What is a FMRI scan?
a technique for measuring brain activity,it works by detecting the changes in blood oxygenation and flow respose to neural activity.Used in important brain surgeries.
12 of 21
Advantages & Disadvantages of a FMRI scan?
ad- can resolve down to 3 cubic millimetres. Dis- any tiny movement can ruin the images
13 of 21
What is a MIR scan?
takes images of almost all the tissue in the body, it can find info about different types of tissue. Changes in the tissues of the brain can help with diagnosis and so determine treatment.

Advantages & Disadvantages of a MIR scan?
ad-contains no ionizing radiation, no documented side effects. Dis- sit till for an hour leading up to claustrophobia, very noisy and is affected by movement.
