Angiography is a specialised x-ray to examine blood vessels using a fluoroscopy machine. It's 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.
An orthopantomogram (OPG) captures x-rays of the head/face on film. A panoramic frontal image, displaying a wide view of the region.
An Echocardiogram, or Cardiac Ultrasound, is used to examine the heart using high frequency sound waves to produce an image.
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.
'Interventional Procedures' refers to a range of minimally invasive specialty procedures, from simple corticosteroid injections to minor surgical procedures.
Mammography or Tomosynthesis produces a 3D image of your breasts, which are used by radiologists to get a more intensive view of the tissue.
MRI is a tunnel that uses a powerful magnet and radiofrequency pulses to collect signals from hydrogen protons in your body.
Nuclear Medicine scans use a radioactive tracer called a radiopharmaceutical. This tracer is usually injected or swallowed, then images are taken using a gamma (SPECT/CT) camera.
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.
Ultrasound uses soundwaves to produce images of structures inside the body. These images can detect a variety of diseases and conditions. It doesn't use any radiation and is generally pain-free.
X-rays produce a two-dimensional image using a light beam to examine internal body parts like bones and organs.
