X-ray Imaging
An X-ray is a common imaging test that can help diagnose, monitor and treat many medical conditions. While the most common use of X-ray imaging is to diagnose issues of the skeletal system, different types of X-rays are used for different purposes. For example, the doctor may order a mammogram to examine the patient’s breasts or they may order an X-ray with a barium enema to get a closer look at the gastrointestinal tract.
How is it performed?
- Based on the part of the body to be imaged, the technician may ask the patient to lie, sit or stand in several positions during the test.
- A specialised plate that contains an X-ray film or sensors is placed behind the area to be imaged and a large camera connected to a steel arm is moved over the patient’s body to capture the images.
- It is important for the patient to stay still while the images are being taken to provide the clearest images. The test is completed when the technician is satisfied with the images gathered.
- If the X-ray is done to diagnose or manage a painful condition, such as a broken bone, the patient may experience pain or discomfort during the test as they will need to hold their body in certain positions while the images are being taken.
- X-rays use small amounts of radiation to create images of the body. The level of radiation exposure is considered safe for most adults.
