What is CT Bone Densitometry?
Quantitative CT Bone Densitometry (QCT BMD) is used to diagnose osteoporosis and determine your risk of a future fracture. QCT Bone Densitometry is not the same as DEXA. Patients should not switch between QCT BMD and DEXA as their values cannot be compared. QCT BMD takes images of the lower back, and uses these to assess the area of the spine which shows earliest changes of bone loss. With these results, the radiologist is able to determine whether you are at risk of developing osteoporosis, or if you have it.
As metal objects can interfere with X-rays, you may be asked to change into a gown, and remove objects such as glasses, jewellery, and even hearing aids. Please inform the radiographer if you are or you suspect you may be pregnant.
The CT scanner looks like a large doughnut, and has a flat table attached which moves through the middle. During your procedure you will lie flat on a table which will travel in and out of the CT scanner while the images are being acquired. The CT machine may tilt during the procedure.
Preparation for your QCT BMD
BMD Examinations do not require any preparation.
After your QCT BMD
After your examination or procedure is finished, the information collected is then assessed by a Radiologist (Doctor who has specialised in Medical Imaging) and these reports will be electronically sent to your doctor with electronic images also being available.
Do I need an appointment?
Appointments are required for all CT examinations. Appointments can be made by calling us on 9964 3757 with your request form and our staff will be happy to assist.
Please note due to changes to the MBS on 1 November 2017 we cannot perform CT Bone Density testing on a patient UNDER THE AGE OF 70.
Who performs CT Bone Densitometry?
All CTs are performed by registered Medical Imaging Technologists (Radiographers). A Radiographer is a specialist technologist who is registered with the Australian Health Practitioner Regulation Agency (AHPRA).
Examinations such as X-ray, CT, and MRI are all performed by Radiographers.
At Geraldton Radiology, we often have student radiographers, or registered radiographers who are training in new areas. In the event that a student/trainee performs your examination, they will be supervised either directly or indirectly by a senior Radiographer.
