RADIOACTIVE TRACER

What are my objectives while studying this topic?


Healthcare professionals use a range of imaging techniques to diagnose illnesses or to monitor the health of an individual. By studying this topic you’ll learn about radioactive tracers and why these are important as a means to diagnosing illnesses.


Why is this important?


Fitness professionals monitor people to assess their fitness to improve their performance.


Healthcare professionals use physiological measurements to monitor the health of patients, to diagnose ill health and to determine a specific treatment for patients.


Can I get an introduction to this topic?


Yes, why not have a look at the following clip:



So, let’s get to it: what is a radioactive tracer?


Studying the blood supply to sites of the body can be used by healthcare professionals in their diagnosis of illnesses. This is done by introducing a 'radioactive tracer', also called a radioactive label, into the blood supply. The useful radiation from the tracer is usually gamma rays which can be detected outside the body. These rays can be used to image an internal organ or structure. An example is the imaging of blood flow in the heart muscle.


What will I be expected to be able to do after studying this topic?


  • State the health and safety considerations to be adhered to by healthcare professionals when using equipment to take radiogram images

  • Describe how a radiogram image is taken and produced

  • Explain the principles of this technique

  • Analyse images to identify features


What are the key words to learn and use for this topic?


  • Angiogram


How long will this topic take to study?


On average you’ll be looking at about one hour of taught time and independent study.
