In comparison to other practices in Western Australia, Envision has, by far, the greatest experience in Cardiac imaging including Cardiac CT, Cardiac MRI and Nuclear Cardiology. Our technology is updated regularly to maintain our world-leading, cutting-edge advantage. We are the preferred provider for the majority of WA cardiologists for a reason – high quality imaging, backed up by experienced, individualized and precise clinical reporting.
Cardiac Imaging at Envision Medical Imaging is a collaboration between Cardiologists, Nuclear Physicians and Radiologists specifically trained in cardiac imaging. Each type of cardiac imaging has its own particular use and is often complimentary to other types of imaging. This multi-modality collaborative approach to cardiac imaging allows comparison and contrast between modalities ensuring the best patient outcomes. Some of our cardiac imaging specialties include:
A Myocardial Perfusion Scan images the blood supply (perfusion) to the heart muscle using a gamma camera. The blood supply is made visible to the camera by the introduction of a small amount of radioactive tracer (radiopharmaceutical or MIBI) injected into an arm vein. Occasionally an alternative tracer called Thallium is used. Depending on the exact heart condition in question, the procedure may be performed at rest, with the heart under stress or, most commonly, both. Myocardial scans give information useful in diagnosing and managing conditions such as coronary artery disease, dead tissue resulting from a lack of blood supply (infarcts) and diseases of the heart muscle (cardiomyopathy). A Stress Myocardial Perfusion Scan examines the blood supply (perfusion) to the heart muscle using a gamma camera. The blood supply is made visible to the camera by the introduction of a small amount of radioactive tracer, (radiopharmaceutical or MIBI) injected into an arm vein. The injection is given during stress exercise on a treadmill, then again while resting later on.
After each injection, a gamma camera placed over the chest takes images (maps) the pattern of tracer accumulated in the heart’s left ventricle, giving information useful in diagnosing and managing conditions such as coronary artery disease, infarcts and diseases of the heart muscle – cardiomyopathy.
CT Coronary Angiography is a specialized form of CT scanning used to take images of the coronary arteries of the heart (angiograms). These arteries supply blood to the heart muscle and disease of these vessels (atherosclerosis) is responsible for most heart attacks.
MRI (Magnetic Resonance Imaging) is 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 obtain the images.
MRI is best at demonstrating the soft tissue structures of the body such as muscles, ligaments,the brain and spinal cord. It can also provide unique diagnostic information for Cardiac, Abdominal and Pelvic imaging making MRI advantageous over other imaging modalities for many clinical questions.
Our practice is equipped with state-of-the-art digital equipment including 1.5T MRI, 3T MRI, The revolutionary Force multislice CT with cardiac capability, ultrasound, and the latest in filmless digital reporting and image archiving and distribution to ensure the highest level of diagnostic service for cardiac patients.
Our up-to date ultrasound technology in three examination rooms is operated by Envision Medical Imaging’s highly experienced sonographers, each with over ten years experience in ultrasound imaging. Our sonographers specialise in vascular, musculoskeletal, obstetrics (pregnancy), paediatrics and general ultrasound.

At Envision, the use of a hybrid scanner allows fusion with low-dose CT, allowing assessment of both structural and functional information in one study, greatly increasing accuracy and reducing scan times.
More about Nuclear Medicine
Envision has two high quality, modern wide-bore MRI scanners (1.5T & 3T). This ensures better images and a far more comfortable experience for patients than many other scanners in WA. Countless patients have experienced the positive difference we provide - our team of caring MRI technicians puts them at ease, even if they are anxious or have had a bad experience in the past. Most importantly, the excellent image quality allows for accurate diagnosis by our specialist MRI Radiologists.

Envision is the only private practice with the new state of the art Siemens CT Somatom Force. Force mode scanning completes a study in less than a second, at even lower dose, providing better image quality. In addition, the protocols are personally prescribed by our radiologists to ensure extremely low levels of radiation, while maintaining optimal image quality. What remains the same is the high quality interpretation by specialists who are experts in their field. The low radiation that you receive from our multi-slice CT scans is comparable to many common dental X-ray series.
We choose Siemens CT scanners because they include control mechanisms that automatically adjust the radiation dose level to the patient’s anatomy, keeping dose to a minimum. It is similar to a highly sophisticated camera’s automatic exposure mode and delivers optimum low dose with high quality images.
More about CT
PET-CT (Positron Emission Tomography - Computed Tomography) is a Nuclear Medicine procedure in which the distribution of a small amount of a radioactive compound injected into the body is imaged at the same time a low dose CT scan is taken. Envision continues to be at the forefront of medical imaging innovation with the introduction of the new Siemens mCT Flow PET-CT. The Siemens mCT Flow PET/CT is the first of its kind to offer personalised imaging, resulting in reduced scan time, a lower radiation dose and a better patient experience. The dual technology of our Siemens PET/CT scanner, located in Envision’s purpose build facilities opened in 2017, allows for the most accurate anatomical localisation of any significant pathology. This assists specialists with the most accurate cancer diagnosis, staging, and measuring the effectiveness of treatments.
