Radiation Safety

Envision has long prided itself on its ability to obtain diagnostically accurate images using the absolute lowest dose of radiation necessary.

We take a very proactive stance regarding patient safety and paramount to this is the issue of radiation dose. Our highly skilled technicians and doctors are continually monitoring, and reviewing our imaging protocols and equipment maintenance procedures to ensure the highest standards in safety are maintained. In addition, all our equipment is updated regularly and routinely serviced and maintained by the equipment manufacturers.

Contrast Injections

Envision uses non-ionic contrast media. This is the safest intravenous contrast media available.

Sometimes an injection of contrast media is indicated to enhance diagnostic accuracy of the examination and enhance the quality. Following an injection of contrast media, you may experience a sensation of heat, an unusual taste or smell and a tingling sensation in the pelvic area. These symptoms are common and very transient. The contrast is eliminated from the body by the kidneys and is excreted in the urine within hours of the initial injection. Patients are encouraged to drink additional clear fluids following their examination to assist in the filtration of the kidneys.

Occasionally, patients can experience minor allergic reactions such as hives. In rare cases, a major allergic reaction can occur. Envision staff are trained in the management of allergic reactions and all sites that administer intravenous contrast media are equipped with emergency medications and equipment, should a patient experience a severe reaction. Patients with a history of allergic reactions, asthma, diabetes, kidney failure or heart disease may require additional precautions to minimise possible complications from a contrast injection.

Infection Control

Envision’s infection control guidelines are based on state and federal guidelines and standards, supported by advice from local specialist Microbiologists and utilize currently accepted practices and procedures.

Envision routinely uses disposable, single use gloves, catheters, needles and syringes. It provides gowns, face masks, protective glasses and sterilising fluids for use in appropriate infection control guidelines. Medical equipment that is to be re-used is cleaned and sterilised in accordance with Australian Standard (AS/NZS 4815).
