Breast Imaging

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…

Benefits

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…

Breast Core Biopsy

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…


Breast Fine Needle Aspiration (FNA)

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…


Breast Hookwire Localisation

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 MRI

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…


Breast Tomosynthesis

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...


Breast Ultrasound

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).…


Cerebral Perfusion Study

What is a cerebral perfusion study? A cerebral perfusion study is a nuclear medicine scan that looks at brain function by demonstrating the amount of blood taken up by the brain cells. Other tests such as computed tomography (CT) and magnetic resonance imaging (MRI) show what the skull, brain and blood vessels look like but a nuclear medicine cerebral perfusion study can…


Clinical Radiologist

Clinical radiologists are highly trained specialist medical doctors. They have undertaken specific postgraduate training in performing and interpreting diagnostic imaging tests and interventional procedures or treatments. Clinical radiologists work with technologically advanced X-ray, ultrasound, and magnetic resonance imaging (MRI) equipment. They…

Contrast Medium: Using Gadolinium or Iodine in Patients with Kidney Problems

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 to examine the images and provide a written report to...


CT Coronary Angiography (CTCA)

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…


Diagnostic Mammography

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…


Foetal MRI

What is a foetal MRI? Magnetic resonance imaging (MRI) is a way of taking detailed pictures of the inside of the body. It is useful for looking at many parts of the body. A foetal MRI gives additional information about your baby from the information received from an ultrasound scan that will have been carried out routinely during your pregnancy....


Iodine-131 Therapy

What is Iodine-131 therapy? The thyroid gland is one of the body’s regulators, controlling and regulating the metabolism (the process of converting food and oxygen into energy). Sometimes the thyroid is overactive and sometimes it is affected by cancer. In both cases treatment with radioactive iodine (Iodine–131 therapy) may be required. Iodine-131 is given as a capsule that looks much...


Iodine-containing contrast medium

What is Iodine-containing contrast medium? Iodine-containing contrast medium (ICCM), sometimes called contrast or contrast medium, is a chemical substance used in medical X-ray imaging. When injected into the body, ICCM shows what is happening inside the hollow parts of the body (like blood vessels, the stomach, bowel or even the fluid around the spinal cord) on X-ray…


Magnetic Resonance Imaging (MRI)

What is magnetic resonance imaging (MRI)? Magnetic resonance imaging (MRI) is a scanning procedure that uses strong magnets and radiofrequency pulses to generate signals from the body. These signals are detected by a radio antenna and processed by a computer to create images (or pictures) of the inside of your body. The MRI scanner is generally shaped like a large, covered…


MIBG scan

What is an MIBG scan? An MIBG scan is a nuclear medicine scan that involves an injection of a radioactive medication (radiopharmaceutical) called iodine-123 meta-iodobenzylguanidine – MIBG for short. The radiopharmaceutical is injected into a vein usually on the inside of the elbow. A special gamma camera (a type of scanner) takes images or pictures to confirm if…
