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 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 widening and bleeding, using a liquid contrast agent (known...
What is nuclear medicine? Nuclear medicine is a medical speciality that involves giving a patient a small amount of radioactive medication, called a radiopharmaceutical. This makes the body slightly radioactive for a short time. A special nuclear medicine camera detects the radiation, which is emitted (released) from the body, and takes images or pictures of how the inside of the...
Interventional radiology is a medical specialisation that involves performing a range of imaging procedures to obtain images of the inside of the body. The interventional radiologist carefully interprets these images to diagnose injury and disease, and to perform a range of interventional medical procedures. Interventional radiologist use imaging techniques…
Health consumers informationWhat 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...
What is contrast medium? Contrast media (sometimes called contrast agents or dye) are chemical substances used in medical X-ray, magnetic resonance imaging (MRI), computed tomography (CT), angiography, and occasionally ultrasound imaging. Contrast media enhance and improve the quality of images (or pictures), so that the radiologist (a specialist doctor trained…
What is a computed tomography coronary angiography (CTCA)? Angiography is the X-ray imaging of blood vessels using contrast agents injected into the bloodstream (see Angiography). CTCA uses computed tomography (CT) scanning to take pictures or images (angiograms) of the coronary arteries of the beating heart. These arteries supply blood to the heart muscle, and…
What is an octreotide scan? Nuclear medicine uses radioactive materials to diagnose or treat diseases. An octreotide scan is one that uses radioactive material to detect certain types of cancers arising from the neuro-endocrine systems (this means cancers that relate to the interaction between the nervous system and hormones from the endocrine system – glands that…
What is a plain radiograph/X-ray? Radiography is the imaging of body structures, or parts of the body, using X-rays. X-rays are a form of radiation (X-radiation) similar to visible light, radio waves and microwaves. X-radiation is special because it has a very high energy level that allows the X-ray beam to penetrate through the body and create an image or picture. Plain…
What is diagnostic mammography? A diagnostic mammogram is an X-ray examination of the breasts. This is performed when a person, their doctor or another health professional discovers unusual signs or symptoms in one or both breasts, i.e. a lump, tenderness, nipple discharge or skin changes. The mammogram confirms whether the changes are benign (non cancerous) and no…
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…
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).…
What 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 a nuclear medicine gated blood pool scan? A nuclear medicine (NM) gated blood pool scan is an imaging test which involves labelling the red blood cells in your blood with a radiopharmaceutical and then measuring the amount of blood in the heart during different parts of the heart beat. The images are acquired on a gamma camera. The filling and emptying of the heart…
What is a vacuum-assisted core biopsy? Vacuum-assisted core biopsy is a safe and minimally invasive procedure in which a sample of breast tissue is removed for examination. When breast imaging shows up very small abnormalities too small to be felt (i.e. anything unusual in the structure of the breast), Vacuum-assisted core biopsy is used to obtain samples of the breast…
What is an X-ray examination? Radiography is the imaging of body structures using X-rays. X-rays are a form of radiation similar to visible light, radio waves, and microwaves. X-radiation is special because it has a very high energy level that allows the X-ray beam to penetrate through the body and create an image or picture. The image is created due to the X-ray beam being…
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 carried…
What is a pleural aspiration? A pleural aspiration is a procedure where a small needle or tube is inserted into the space between the lung and chest wall to remove fluid that has accumulated around the lung. This space is called the pleural space. Pleural aspiration is usually carried out to determine why there is fluid around the lung (diagnostic procedure) or to improve…
