Radiation

Cape Radiology understands that patients may be concerned about possible radiation exposure. So please know: 

• Only CT Scans and X-rays use radiation. Other examinations, such as an MRI or Ultrasound, do not use ionising radiation. 
• The equipment used at Cape Radiology is registered with the Directorate of Radiation control and complies with the Radiation Control Act. 
• The equipment is modern and undergoes regular servicing.
• The exposure to radiation, during a CT Scan or X-ray, needs to be weighed up with the benefits of learning the results of these examinations.
• Our protocols are continually reviewed and are designed to minimise the amount of radiation delivered to you without compromising image quality.
• All our staff are appropriately qualified and possess the necessary training to operate equipment that emits radiation. 

If you are at all concerned, please discuss this with your doctor and our staff.

Contrast

If you are having an MRI or CT scan, you may require “contrast” (an intravenous substance) to be injected. It is often referred to as “dye”. In this instance, you will be asked to consent to contrast being administered.

After being injected, contrast enters the bloodstream and then enters certain types of tissue in the body. As it does so, it highlights the difference between normal and abnormal tissue (thus the name “contrast”). Contrast is not radioactive and is naturally removed from the body through the kidneys (urine) and liver (into the bowel).

Before your examination, you will be asked to complete a form regarding allergies and medical history. Depending on certain medical criteria, the radiographer or receptionist may ask for your most recent renal function results. You may be required to have blood tests to check your renal function.

Infection Control

Cape Radiology strictly adheres to the universal precautions for infection control.
