Question:
Which among the following technique is used to detect cancers of the internal organs ?
Options:
Radiography (use of X-rays).
CT (computed tomography) .
MRI (magnetic resonance imaging).
All of these.
Correct Answer:
All of these.
Explanation:
Techniques like radiography (use of X-rays), CT (computed tomography) and MRI (magnetic resonance imaging) are very useful to detect cancers of the internal organs. Computed tomography uses X-rays to generate a three-dimensional image of the internals of an object. MRI uses strong magnetic fields and non-ionising radiations to accurately detect pathological and physiological changes in the living tissue.
