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 has removed an angiography.

C) Computerised Axial Tomography (CAT) shows detailed internal structure as seen in a section of the body.

D) X -ray provides clear and detailed images of organs like prostate glands and lungs.

Which two of the above statements are correct? 

• B and D

• C and D

• A and C

• A and B

C.

A and C

It is almost impossible to repair intracardiac defects surgically while the heart is still pumping. Therefore, many types of artificial lung machines have been developed to take the place of heart and lungs during the course of operation. Angiography is a radiographic visualisation of blood vessels of a region/organ after injecting a radio-opaque /contrast agent computerised axial tomography (CAT) shows detailed internal structures as seen in a section of the body (eg, iodine) or fluoroscopic chemical.
Digital subtraction angiography is an imaging technique that produces clear views of flowing blood in vessels and indicates the presence of a blockage.
X - rays have a remarkable ability to penetrate materials, which do not transmit visible light. X-rays imaging is commonly employed for diagnosing disease of heart, lungs and bones.
