3
Q
What is a magnetic resonance imaging scna
A

Q
What are the advantages
A
- Allows non invasive procedures to take place
- Allows non-exposure to radiation and therefore reduces risk of radiation induced cancer
- MRI has better resolution so it is helpful for detecting abnormalities in soft tissue such as the brain
5
Q
What are the disadvantages
A
- People with metal in their bodies cannot go inside because the MRI is a large magnetic field and can result in death of the patient.
- It is an issue for people with clausterphobia because the patient has to stay in a narrow tube with a loud noise for several minutes
- It is also an issue for small children because the patient must stay in the same position for a long time, and children can be very restless.
- Very expensive
- The high resolution can detect abnormalities that are not related to the symptoms of the patient.
