Envision is the premier provider of MRI scans in Perth.
Magnetic Resonance Imaging or MRI scans are a way of creating pictures of your body that does not use X-rays or radiation. MRI uses a very powerful magnetic field in combination with a rapidly switching Radio-Frequency (RF) to create the images. These scans do not use ionizing radiation like X-rays or CT scanning and no known harmful effects have been demonstrated.
MRI scans are best for investigating the soft tissue structures of the body such as muscles, ligaments, the brain and the spinal cord. They can also provide unique diagnostic information for Cardiac, Abdominal and Pelvic imaging.
Envision’s MRI Technology
Envision has two high-quality, modern wide-bore MRI scanners (1.5T & 3T). This ensures better images and a far more comfortable experience for you than many other scanners in WA. Our team of caring MRI techs will put you at ease, even if you are anxious. Countless patients have experienced the positive difference we provide. Most importantly, the excellent image quality allows for accurate diagnosis by our specialist Radiologists.
In some cases, you will require an injection of Gadolinium-based contrast agent (dye) which is injected via a vein in your arm.
Risks associated with the MRI procedure
An allergic reaction to intravenous contrast material can simulate short term allergic response such as itching, a rash or hives. A more serious allergic reaction to intravenous contrast is called an anaphylactic reaction. When this occurs, the patient may experience severe hives and/or extreme difficulty in breathing. This reaction is extremely rare and requires emergency treatment.
