Question

Explain why MRI is safe compared to X-ray scanner using the energy of the electromagnetic radiation.

Answer 1

MRI is safe compared to X-ray scanner because :-

Parameter	MRI	X-RAY
Radiation exposure	None. MRI machines do not emit ionizing radiation.	Exposure to dangerous ionizing radiation.
Effects on the body	No biological hazards have been reported with the use of MRI. However, some may be allergic to the contrast dye, which is also inappropriate for those suffering from kidney or liver disorders.	The powerful rays have the ability to create birth defects and diseases and can also alter the DNA.
Hazard Level	With the MRI several cross sectional images can be taken at the same time without creating any biological hazards.	The radiation can cause damage to the soft tissues if exposed for a prolonged period.
