What is an 18-20 week screening pregnancy ultrasound? An 18–20 week pregnancy screening ultrasound is part of the routine care during pregnancy. Screening is carried out at this stage in the pregnancy because the foetus (unborn baby) is big enough for its body structure and development to be assessed. It also provides additional information such as; the number of foetuses,…
Abdominal imaging is a subspecialty of diagnostic radiology which involves imaging the abdomen and pelvis, including the genitals, urinary organs and gastrointestinal tract, to diagnose and plan treatment for disease. Abdominal imaging radiologists use imaging to diagnose diseases of the: liver, bladder and kidneys prostate and uterus pancreas colon gallbladder…
Health professional informationWhat is amniocentesis? Amniocentesis is a procedure where a needle is inserted into the abdomen to obtain a small amount of amniotic fluid. The foetus grows in the uterus, or womb, inside a bag called the “amniotic sac” surrounded by amniotic fluid. Amniotic fluid is made by the placenta (the organ that develops inside the uterus to supply food and oxygen, through the…
What is angiography? Angiography is the X-ray imaging of blood vessels using contrast agents injected into the bloodstream through a thin plastic tube (catheter) that is placed directly in the blood vessel. The images taken are called angiograms. Angiography provides information about blood vessel abnormalities, such as narrowing, blockage, inflammation, abnormal…
What is an angioplasty and stent insertion? Angioplasty and stent insertion is used to treat narrowing in an artery. Angioplasty uses a small, sausage-shaped balloon to stretch the artery open and improve blood flow. The stent is a small, metal cylinder that acts like a small scaffold to hold the artery permanently open. Angioplasty is the name of the procedure...
What is an arthrogram? An arthrogram is an X-ray image or picture of the inside of a joint (e.g. shoulder, knee, wrist, ankle) after a contrast medium (sometimes referred to as a contrast agent or “dye”) is injected into the joint. An arthrogram provides a clear image of the soft tissue in the joint (e.g. ligaments and cartilage) so that a more accurate diagnosis about…
What is an ascitic tap? An ascitic tap is a medical procedure where a needle is used to drain fluid that is trapped in an internal body cavity, most commonly the abdomen (belly). Fluid may have to be drained from the abdomen for different reasons, such as if the fluid is stretching the abdomen and causing pain; if the fluid is infected; or if a doctor needs to analyse the fluid…
The rapid advances in clinical radiology technology and theory have dramatically improved the diagnosis and treatment of illness and injury. Clinical radiology has a range of benefits for the patient: It can eliminate the need for exploratory surgery. It is used to determine when a patient needs surgery. It assists in making a diagnosis and further management of most…
What is a biliary drainage? Biliary drainage is the insertion of a tube into the bile duct. This is most commonly carried out when the bile ducts are blocked.The bile ducts normally allow bile (a green-brown fluid that is produced by the liver to help with the digestion of fats) to drain from the liver to the small intestine. When the bile ducts are blocked, bile cannot leave…
What is a bone mineral density scan? A dual-energy X-ray absorptiometry scan (DXA), or bone density scan, is a special type of X-ray that measures bone mineral density (BMD). It provides information about bone strength or fragility and the risk of fractures or broken bones. The higher the density, generally, the lower the risk of fracture. The spine and one or both hips…
What is a breast core biopsy? A breast core biopsy is where a special needle (or probe) is inserted into the breast to take a small sample of breast tissue from an area of concern so that it can be sent to a laboratory for testing. It is done using local anaesthetic to numb the breast in the area that is being biopsied. An abnormality may have been identified on a scan or X-ray image…
What is a breast fine needle aspiration? A breast fine needle aspiration (FNA) is a quick and simple procedure to perform, which removes some fluid or cells from a breast lesion or cyst (a lump, sore or swelling) with a fine needle similar to a blood sample needle. The sample of fluid or cells is smeared on a glass slide and sent to a pathology laboratory to be examined by a specialist…
What is a breast hookwire localisation? Many tests have been developed to find breast cancer early. Tests, such as mammography, ultrasound and magnetic resonance imaging (MRI), can show abnormalities in the breast that cannot be felt by a woman or her doctor. If an abnormality that cannot be easily felt needs to be surgically removed, surgeons need a marker to guide to…
Breast imaging is a subspecialty of diagnostic radiology. It involves a range of imaging procedures. Screening mammography is used to detect breast cancer via a low-dose X-ray before any symptoms are evident. This allows for early treatment and intervention. In Australia free breast screening is available to women aged 50-74 every two years. Diagnostic mammography…
Health professional informationWhat is a breast MRI? A breast MRI (magnetic resonance imaging) is a medical test where magnetic fields, radiowaves and an advanced computer are used to produce very detailed images of the breasts without using X-rays. The MRI machine is a large cylinder-shaped tube surrounded by a circular magnet. You will lie on a sliding examination table that is moved into the centre…
What is Breast Tomosynthesis? Breast tomosynthesis (often referred to as 3D mammography) is a type of X-ray examination of the breast. It is a relatively new technology, and research about how to fully utilise it is still being carried out. It has already been shown to be beneficial in the detection of small breast cancers compared with conventional mammography, particularly...
What is a breast ultrasound? Breast ultrasound is the examination of the breast tissue using an ultrasound scan. Ultrasound uses high frequency soundwaves to produce images (or pictures) of the body that are displayed on a screen. Ultrasound of the breast helps to distinguish fluid filled lumps in the breast (cysts) from solid lumps which may be cancerous or benign (non-cancerous).…
