At Wesley Medical Imaging, we are committed to providing our patients with the highest quality of medical imaging and diagnostic services in the most timely manner possible and within an environment of care, compassion and convenience.
We’ve put together some helpful information to help you better understand diagnostic imaging.
What is Diagnostic Imaging?
Diagnostic imaging, medical imaging and radiology are generic terms that cover the capturing and interpretation of images for the purpose of medical diagnosis.
Diagnostic Imaging Procedures
Includes general x-ray, bone densitometry (a technique that measures bone density), and mammography (a technique for examining the breast).
A procedure in which high energy sound waves are used to generate cross sectional and 3D images of soft tissue. Doppler ultrasound is capable of demonstrating blood flow and abnormalities associated with blood vessels.
Computed Tomography (CT)
A procedure in which a computer is able to analyse information received from x-ray beams to generate multiple cross-sectional and 3D images of a particular organ or area of the body including skeletal detail.
Magnetic Resonance Imaging (MRI)
Magnetic Resonance Imaging (MRI) uses a very powerful magnet and radio-frequency pulses to collect signals that are then processed by a computer to form a picture of the body part being studied. Images line up like slices from a loaf of bread.
MRI gives a detailed picture of the soft tissues of the body e.g. muscles, ligaments, brain tissue, discs and blood vessels.
A sub-specialty where the patient is given a low dose radiation isotope which is then detected by a gamma camera to indicate metabolic and biological functions within the body. Nuclear Medicine also includes Positron Emission Tomography (PET), a precise imaging procedure often used as a tool for cancer diagnosis, staging and monitoring.
A sub-speciality within the field of diagnostic imaging which uses various imaging techniques (such as x-ray, CT scans, MRI scans, and Ultrasound) to guide the placement of needles, catheters, drains and stents inside a patient to diagnose or treat an array of conditions.
Key People Involved In Diagnostic Imaging
A medical specialist who has completed at least 12 years of training including dedicated post medical school training in diagnostic radiology. All Australian radiologists are credentialed by The Royal Australian and New Zealand College of Radiologists. They are responsible for interpreting diagnostic images of patients for medical diagnostic purposes.
A Nuclear Physician
A medical specialist who has completed at least 12 years of training including dedicated post medical school training in Nuclear Medicine. All Australian nuclear physicians are credentialed by The Royal Australasian College of Physicians. They are responsible for interpreting diagnostic images of patients for medical diagnostic purposes.
Radiographers and Sonographers
Professionally trained technologists who have completed a University degree with the option of further post graduate study required for specific modalities such as Ultrasound. They work with the radiologist to operate the specialised equipment used to capture the diagnostic images of patients, used for medical diagnostic purposes.
A Nuclear Medicine Technologist
A professionally trained technologist who has completed a University degree specialising in Nuclear Medicine. They work with the nuclear physicians and Radiologists to operate the specialised equipment used to capture the diagnostic images of patients used for medical diagnostic purposes.
