Read the leaflet on X rays and other scanning techniques. Task 1: Draw up a table in your books explaining how each of the imaging methods works. Task 2 Give four examples of the risk associated with examinations of different parts of the body Task 3 Any medical procedure involving radiation involves a risk. Draw up a table giving your opinion on the benefits and drawbacks of treatments involving radiation

Foundation questions Q1 How do X rays produce a picture of the inside of your body? Q2 What is a difference between a fluoroscopy picture and a single X ray? Q3 What must the patient do in order to give moving pictures of the gut? Q4 How does the image from a CT scan differ from a single X ray? Q5 How does the radiation dose from Fluoroscopy and CT scanning compare with the dose from an X ray? Q6 What type of radiation is used in isotope scanning? Q7 Give one reason why MRI scanning cannot be used for all medical images. Q8 What are the chances of developing cancer from: (a) A dental X ray (b) A CT scan of the abdomen Q9 Why is a developing baby in the womb more at risk from X rays?
