Give the full form of CT and MRI

Give the full form of CT and MRI. How are they different from each other? Where are they used?

CT is Computed Tomography. CT uses X-rays to generate 3-D images of internal organs.
MRI is Magnetic Resonance Imaging. MRI uses strong magnetic fields and non-ionising radiations to detect pathological and physiological changes in the living tissue accurately.
Both are used in cancer detection.
