Q. 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 two of the above statements are correct?
A) a and b
B) b and d
C) c and d
D) a and c
Explanation
[Solution from source] A heart-lung machine takes over circulation during open-heart surgery, and CAT scanning builds cross-sectional images of internal structures. Angiography only images vessels (angioplasty removes blockages), and plain X-rays do not give detailed soft-tissue images of organs such as the prostate. Answer (4).
