(a)
Interpretation:
The type of radiation used in MRI has to be noted.
Concept Introduction:
Magnetic resonance imaging (MRI) is technique used for medical imaging purpose. MRI uses strong magnetic field and radio waves for imaging. The principle used in MRI is same as that of NMR. NMR active nucleus like hydrogen nucleus can be detected through this device. These nuclei will absorb radio waves and emitted back it when placed in an external magnetic field, and can be detected. Since body contains water and fat in large quantities, the hydrogen nuclei from water and fat are detected through MRI and images are produced.
(b)
Interpretation:
The type of image produced and radiation used in MRI and CT has to be compared.

Computerized Tomography (CT) can take the images of internal part of body using X-rays.
(c)
Interpretation:
The reason for the abbreviation MRI is used in medical field rather than NMR, even though MRI is based on NMR has to be explained.
