Question:

Match the Column I with Column II :

Column I (Biomedical techniques) Column II(Features)
A. Computed tomography 1. A piece of the suspected tissue cut into thin sections, stained and examined under microscope
B. Blood or Bone marrow test 2. X-rays are used to detect cancer of the internal organs
C. Radiography 3. Leukaemia
D. Biopsy 4. Uses X-rays to generate a three- dimentional image of the internals of an object

 

 

Options:

A-1,B-2,C-3,D-4

A-4,B-3,C-2,D-1

A-4,B-3,C-1,D-2

A-1,B-3,C-4,D-1

Correct Answer:

A-4,B-3,C-2,D-1

Explanation:

The correct answer is Option (2) - A-4,B-3,C-2,D-1

Column I (Biomedical techniques) Column II(Features)
A. Computed tomography 4. Uses X-rays to generate a three- dimentional image of the internals of an object
B. Blood or Bone marrow test 3. Leukaemia
C. Radiography 2. X-rays are used to detect cancer of the internal organs
D. Biopsy 1. A piece of the suspected tissue cut into thin sections, stained and examined under microscope

Cancer detection is based on biopsy and histopathological studies of the tissue and blood and bone marrow tests for increased cell counts in the case of leukemias. In biopsy, a piece of the suspected tissue cut into thin sections is stained and examined under microscope (histopathological studies) by a pathologist. 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 tissues.
