Q. Which one of the following techniques is safest for the detection of cancers?
(a) Radiography (X-ray)
(b) Computed tomography (CT)
(c) Histopathological studies
(d) Magnetic resonance imaging (MRI)
Solution : Correct option : C Magnetic Resonance Imaging (MRI) is non -invasive technique that uses strong magnetic field and provides information about chemistry, metabolic and biochemical data of a tissue without time-consuming chemical analysis can be done. And it is the safest technique for the detection of cancer since it does not utilize radiations and therefore, does not cause any side effect. So, the correct answer is ‘Magnetic resonance imaging (MRI)’.
