Question

Consider the following statements about biomedical technologies,
(a) During open heart surgery blood is circulated in the heart-lung machine.
(b) Blockage in coronary arteries is removed by angiography.
(c) Computerised Axial Tomography (CAT) shows detailed internal structure as seen in a section of body.
(d) X-ray provides clear and detailed images of organs like prostate glands and lungs.
Which of the following statements are correct?

• A. (c) and (d)
  
• B. (a) and (c)
  
• C. (a) and (b)
  
• D. (b) and (d)
  

Answer 1

The correct option is B (a) and (c)

During the open heart surgery, the patient is connected to a hear-lung bypass machine. The machine moves blood away from the heart so that the surgeon can operate.
Computerized axial tomography is a form of tomography in which a computer controls the motion of X-ray source and detectors, processes the data, and produces the image. It shows the internal structures of the body.
X-ray imaging creates pictures of the inside of the body and the images show the parts of the body in different shades of black and white. It does not show clear pictures of organs.
Angiography is a minimally invasive medical test that helps physicians diagnose and treat medical conditions like it treats blockages of coronary arteries.
Computerized axial tomography is a form of tomography in which a computer controls the motion of X-ray source and detectors, processes the data, and produces the image. It shows the internal structures of the body.
Therefore, the correct answer is option B.
