Angiography is a specialised x-ray to examine blood vessels using a fluoroscopy
performed by inserting a thin tube, or catheter, then injecting an x-ray dye (called contrast
media) into an artery to see the vessels' course and flow.
Bone mineral densitometry (BMD) scans use a small dose of radiation to measure the density of
bones. During the scan, patients lie on their back on a wide, flat bed. A camera arm will pass over
the top of them taking a series of images.
A CT scanner uses x-rays to create multi-dimensional images of a specific body area which help to
diagnose medical conditions. In some cases, contrast media may be injected to provide further
detail. You'll lie on a table which moves inside the scanner to obtain images.
A fluoroscopy is helpful in diagnosing and treating abnormalities in the body. It examines entire
systems, producing moving images that allow doctors to see if there's a blood clot in veins or
arteries, if bones are healthy, or if the digestive tract is working properly.
PET/CT imaging uses a radioactive tracer called a positron emitter. A small amount of this tracer
is injected into a patient's vein. Images are then taken to show the distribution of the
tracer in the body.
