4. CT scanning is a combination of special x-ray equipment and sophisticated computers. The two together are used to produce different pictures of the body’s insides

5. CT scans are used to scan parts of your body such as: organs, bones, soft tissue and blood vessels.

6. Doctors sometimes choose the CT scan mostly because it gives clearer details than conventional X-ray machines.

8. CT scans can quickly identify injuries in the lungs, heart, liver, spleen, kidneys, bowel or other internal organs.

9. CT examinations can be use to measure mineral densities inside of bones for the detection of osteoporosis ,or the decease where bones are on the verge of fracturing due to decreasing amount of minerals.

10. CT examinations could also be used to plan for surgeries such as, organ transplants.Press It

12. It can image bones, soft tissues and blood vessels at the same time.

13. CT scanning are very fast and simple.

14. CT scanning can be performed even though you may have an implant of any kind, unlike MRI.

15. No radiation remains inside the patient after the examination.

16. There is always a slight chance of getting cancer from the excessive exposure of radiation.

17. The amount of radiation from one exam is around the same amount that you would receive normaly in 3 years.

19. Nuclear medicine is a branch of medical imaging that requires small amount of radio active materials to find or treat a variety of deceases.

20. The machine looks similar to a CT or a MRI scanner. So it looks like a round doughnut with a desk that moves through it. How does it work ? First the physician would either inject , make you swallow or inhale as a gas a radioactive material called radiopharmaceutical or radiotracer. Then the material will gather in the organs or area of the body which is being examined. When it gathers this material gives off a smallamount of energy. After that the PETscannerdetects this energy given of by the radioactivematerial ,and with the help of a computer a picture is then formed. What and Why is it Used for? It is used to findcancerinside your body. When found it could also benefit the doctor, so that the doctors could find a way to cureit. Used to see and identify the spreading of cancercells. So the doctors can tell if it is dangerous or not. It can detect brain disorders such as Alzheimer, Parkinson’s decease and more. It can determine the effects of a heartattack Press It

24. The magnetic fields are being created by the electricity passing through the wire coils inside the machine.

25. The magnetic fields effect the body’s atoms and causing them to move into a different position. As the atoms go back into the original position they give of radio waves of their own

27. A person who is very large in size may sometime not fit into the hole of a typical MRI machine.

29. The DSR machine was developed in the 1970s and 1980s.

30. It is like a CTscanner, but instead of producing a 2Dimages the DSR scanner produces3Dimages.

31. The imagesproduced by the DSR arealso in real-time

33. Because ultrasounds are takenreal-time they canshow the movement and structures of the body’s internal organs.

35. Ultrasounds are widelyused and cost less than otherimaging techniques.

36. All ultrasounds does not require any kind or radiation.

38. The ultrasoundmachineworks by sending high-density sound waves into the area of the patient being examined.

39. When a sound wave hit something it bounces back or echoes.
