CT (Computed Tomography)
Information for patients attending Alfred Health Radiology
What is a CT scan examination?
CT uses x-rays and a computer to produce 2D or 3D images. CT can show bones, soft tissues and blood vessels well.
We use the newest type of CT technology called 'Multislice CT' which covers the area to be examined with thinner slices and gets more detailed images in a shorter time.
What are the different CT procedures?
We offer a wide range of diagnostic and interventional CT procedures, including:
- Sinuses, Face
- Petrous Temporal bones
- CT upper and lower extremities (e.g. CT shoulder, hand, wrist, elbow, ankle, foot)
- Abdomen and Pelvis, including multiphase hepatic, renal or pancreatic studies.
- CT Angiogram (looking at the blood vessels)
- CT Intravenous Pyelogram
- CT Intravenous Cholangiogram
- CT colonoscopy
- Nerve root injection
- Facet joint injection
- Core and Fine needle aspiration biopsy
- CT Guided interventional procedures
