Question
1. What is a major health concern with MRI?
Localized burns due to metallic implants.
Radiation dose
Reaction to applied drugs
Extreme cold
2. Select one of the following objects that you think would always be safe in the MRI suite.
A wheelchair.
Scissors
A stretcher
None of the above
3. Comparing MRI to CT, which is true?
Both methods use X-rays, but exposure is higher with CT
CT reveals soft structures, while MRI is better at dense material, such as bone
Both methods produce cross-sectional images at a specified plane through the body
MRI scans take less time
4. Increasing the magnetic field in MRI ....
reduces the risk of tissue heating.
produces less susceptibility artifacts.
increases the signal to noise.
reduces the danger from metallic projectiles.
4. Increasing the magnetic field in MRI ....
Explanation / Answer
Answer 1 - a major health concern with MRI is localized burn due to metallic implant.
Reason - MRI is done without using any ionizing radiation , so patient are not exposed to their harmful effect but since MRI involves a strong ststic magnetic field ,time dependent magnetic filed ,and radio frequency energy each of which attract the nearby metallic object which can cause damage to the patient .
