Magnetic Resonance Imagining Scan Is Done On :

A: Human Body
B: Aeroplane Wheels
C: Machinery
D: Animals

The answer is: A

Explanation

Magnetic Resonance Imaging (MRI) scans are primarily done on human bodies, although they can also be performed on animals for research purposes. MRI is a medical imaging technique that uses a strong magnetic field and radio waves to create detailed images of internal body structures such as organs, bones, and soft tissues.

MRI scans are used to diagnose and monitor a wide range of medical conditions, including neurological disorders, cancer, joint and bone problems, and cardiovascular disease. They are non-invasive and do not involve exposure to ionizing radiation, making them a safe and useful tool for medical imaging.

MRI scans are not typically performed on aeroplane wheels or machinery, as these objects do not have internal structures that need to be imaged. However, MRI technology is sometimes used in materials science research to study the microstructure of materials such as metals and polymers.
