Question

the physical phenomenon that mri is based on does not depend on ionizing radiation, but on other properties of atoms instead. what is this phenomenon called?
○ gamma-ray bursts
○ positron emission
○ x-ray propagation
○ nuclear magnetic resonance

Explanation:

• Gamma - ray bursts are extremely energetic explosions in space, not related to MRI.
• Positron emission is used in PET scans, not MRI.
• X - ray propagation involves ionizing radiation, while MRI does not use ionizing radiation.
• Nuclear magnetic resonance (NMR) is the physical phenomenon on which MRI (Magnetic Resonance Imaging) is based. It utilizes the magnetic properties of atomic nuclei (like protons in hydrogen atoms in the body) and does not involve ionizing radiation.

Answer:

D. nuclear magnetic resonance
