CT Scan
CT angio one part is a general catalogue entry for a CT angiography study covering a single body region, the specific area chosen by your doctor rather than fixed in advance. CT angiography combines an injection of iodine-based contrast dye with CT scanning to produce detailed images of blood vessels. It is used to look for narrowing, blockages, aneurysms, or other vessel abnormalities in the area your doctor is investigating. This entry does not name one fixed body part, because the region depends entirely on your symptoms and your doctor's referral. Ask your doctor which part of the body this scan will cover before your appointment.
This scan checks the blood vessels in the single region your doctor specifies, looking for narrowing, blockages, aneurysms, clots, or unusual vessel patterns. The exact vessels examined depend on the body part being studied. Your report describes what the images show in that region.
CT angiography (CTA) uses an intravenous injection of contrast dye along with a CT scanner to create detailed pictures of blood vessels anywhere in the body. This catalogue entry, CT angio one part, covers a single body region. It does not specify which region in advance, because that depends on what your doctor needs to investigate.
- Narrowing or blockage of an artery - An aneurysm, a bulge in a vessel wall - A blood clot - Abnormal vessel connections - The blood supply to an organ or limb before surgery
Doctors order CT angiography for many different reasons, from checking blood flow to a limb, to investigating an organ, to planning surgery. Because the appropriate region depends entirely on your symptoms and history, this booking covers whichever single area your doctor has specified on your referral.
The scan uses iodine-based contrast dye, so tell your doctor about any past allergic reaction to contrast, or about kidney disease, before your appointment. It also involves radiation exposure. Tell the centre if you are or might be pregnant, since CT scanning is generally avoided during pregnancy unless necessary.
CT angio one part covers a single body region, but the exact area depends on your doctor's referral. Check your prescription or ask the centre if you are unsure.
Yes. CT angiography uses an iodine-based contrast dye injected into a vein to make the blood vessels visible on the scan.
No. CT angio extra part is a separate catalogue entry used when a second body region needs to be covered in the same visit, in addition to the first.
Tell your doctor about any past reaction to contrast dye or iodine before booking. They may adjust the plan or consider an alternative.
This page is general information about the test, not medical advice. Your own report's reference ranges apply — please discuss your results with your doctor.
It shows the blood vessels in the region examined, which your doctor uses alongside your symptoms and other tests to reach a diagnosis. Ask your doctor to explain your specific case.
Preparation can vary depending on the body region and your health history. Ask your doctor or the centre for instructions before your appointment.
CT angiography does involve radiation exposure, though the amount depends on the region scanned. Tell the centre if there's any chance you could be pregnant.
