Digital X-ray examination is used to create images of your internal organs or bones to help diagnose conditions or injuries. The X-ray machine emits a small amount of ionising radiation. This radiation passes through your body and falls on a film or similar device to produce the image. The dose of radiation you will receive depends on the area of your body being examined. Smaller areas such as the hand will receive a lesser dose, compared to a larger area such as the spine. On average, the dose of radiation is roughly the same as you would receive from the general environment in about one week.

The computed tomography (CT) scan is a medical imaging procedure that uses x-rays and digital computer technology to create detailed two or three-dimensional images of the body. Unlike other forms of medical imaging, the CT scan can make an image of everytype of body structure at once, including bone, blood vessels and soft tissue. Multiple x-ray projections are taken in thin cross-sections along the person’s body (imagine a loaf of sliced bread). The detectors collect the x-ray information from each cross-section and send them to a special computer that combines them into an image.

Bone densitometry testing or bone mass measurement is a medical procedure used to determine bone density or strength. It can identify osteoporosis (when bones become less dense, lose strength and break more easily due to calcium loss) or osteopaenia, a milder form of bone loss. There are various different procedures that can measure bone density. The majority of these procedures are quick and pain-free. Dual energy x-ray absorptiometry (DEXA), which uses a special x-ray scanning machine to measure bone density, is the most popular technique as it is fast and highly accurate.


What is an ultrasound examination?

Ultrasound uses sound waves to produce an image (like sonar). A small plastic transducer is held against the patient's skin, allowing underlying structures to be seen by bouncing sound waves through the body. Ultrasound can show soft tissues very well. Ultrasound scanning can be used to aid interventional procedures.

What types of Ultrasound examination are offered at My Radiology Centre?

  • Carotid Doppler
  • Arterial and Abdominal Aortic Doppler
  • DVT Screening Doppler
  • Interventional Ultrasound
  • Breast Ultrasound
  • Paediatric Ultrasound
  • Pelvic and Transvaginal Ultrasound
  • Pregnancy Ultrasound
Preparing for my Ultrasound Scan

If you have been referred for an ultrasound scan by your doctor and would like to make a booking, please contact us on (08) 9434 9620

Before the Ultrasound Scan

You may be asked to fast, drink water, and hold your bladder full. Please continue your regular medication, unless advised not to by your doctor.

You may be asked to change into a hospital gown.

During the Ultrasound Scan

A Sonographer will perform this scan.

Ultrasound scans generally take 30 minutes, but this may vary. Your sonographer will advise you on the day.

He or she will apply ultrasound gel to the part of your body being scanned, and move the transducer over that area. You may be asked to move into different positions to scan different body parts.

To ensure a thorough examination, the sonographer may need to ask you personal questions about your health or condition.

For certain conditions an internal ultrasound may be required to complete the examination.

After the Ultrasound Scan?

Eat and drink normally after the examination.

Return to your doctor to discuss the examination results.

If you have had an interventional procedure, you will be given an information sheet at discharge about your procedure.

The radiologist's report and your images are automatically forwarded to your doctor.

Radiation Safety and Radiation Dose

Radiation Safety and Radiation Dose

My Radiology Centre’s radiographers are all highly trained and skilled in producing diagnostic images with the minimum radiation dose required, using a principle known as the “ALARA” principle (“as low as reasonably achievable). In the vast majority of cases, the radiation dose a patient is exposed to with modern radiology equipment is very low, often less than a few days normal exposure to cosmic radiation that we are all exposed to fro the universe around us, or that of a long-haul flight!

If you are concerned regarding the need for an examination, and the potential risks of radiation exposure, then simply ask the radiographer and you will be given as much information as needed for you to make an informed decision about undergoing the procedure. Rest assured that our team are very aware of the Benefit Vs. Risk of ionising radiation for imaging purposes, and will act in the best interests and safety of you, the patient.
