Frequently Asked Questions
How do I get an x-ray, ultrasound, MRI or CT scan?
A referral from a suitably qualified referrer is necessary for most radiology type examinations. GP's, Specialists, Midwives, Physiotherapists, Osteopaths, Dentists and Chiropractors are some of the medical professionals that can request an examination.
At Bay Radiology there are two examinations for which you can self-refer, a screeening mammogram (if you are over 40 years of age and do not have any current symptoms of concern) and a Bone Density scan.
What is MRI?
MRI is a form of scanning that uses a magnetic field to give in depth views of the body. The scanner itself, coupled with a sophisticated computer software program, allows Radiologists to see very detailed images of the internal organs, soft tissues, tendons and muscles of many parts of the body. MRI stands for Magnetic Resonance Imaging.
Is ultrasound safe?
Ultrasound scanning has been undertaken for many years. Current knowledge tells us that it is safe to use ultrasound scanning on pregnant women with no known detrimental effects on mother or baby.
What is nuchal translucency scanning?
In every fetus there is a fluid thickening behind the neck. This thickening is called the Nuchal Translucency. Studies have found that if the fetus has an increased nuchal translucency this indicates an increased risk of a chromosomal abnormality in the fetus.
What is CT?
CT stands for Computerised Tomography. CT scans are done on a highly sophisticated scanner which passes a very thin beam of radiation through the body. The scanner, coupled with a computer software program, produces images in multiple planes through the body and show internal organs and boney structures.
What are X-rays?
Xrays are a form of unseen, high frequency elctromagnetic radiation. X-rays are very small and energetic and are produced by accelerating electrons at a metal target. X-rays are used in various medical applications, especially for imaging.
How many X-rays is it safe to have?
Small doses of radiation are not harmful. When you take an aeroplane trip you are receiving radiation just as you are when out in the sun. The small doses that you receive having a diagnostic x-ray image taken are negligible, however x-rays are less desirable in the early stages of pregnancy. It is important that you tell the MRT (Radiographer) of any possibility that you may be pregnant BEFORE having your x-ray taken.
