Magnetic Resonance Imaging (MRI)

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... View Article


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.... View Article

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... View Article

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... View Article

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... View Article

Gadolinium Contrast Medium (MRI Contrast agents)

What is gadolinium contrast medium? Gadolinium contrast media (sometimes called a MRI contrast media, agents or ‘dyes’) are chemical substances used in magnetic resonance imaging (MRI) scans. When injected into the body, gadolinium contrast medium enhances and improves the quality of the MRI images (or pictures). This allows the radiologist (a specialist doctor trained to... View Article

MRI Enterography or Enteroclysis

What is an MRI enterography or enteroclysis? Entero means small bowel and graphy means image, so enterography is taking images (or pictures) of the small bowel after drinking fluid to make the small bowel stand out on the images. Enteroclysis means a tube has been placed in the small bowel through the stomach. Whether enterography... View Article

MRI Heart (Cardiac MRI)

What is a cardiac MRI? Magnetic resonance imaging (MRI) uses a high-strength magnet and radio waves to scan the body and produce images or pictures. MRI does not use ionising radiation, which is required for many other types of imaging, and is not known to have any long-term harmful effects. Cardiac MRI is imaging relating... View Article

MRI of the Prostate

What is an MRI scan of the prostate? A magnetic resonance imaging (MRI) scanner uses strong magnetic fields to create an image (or picture) of the prostate and surrounding tissues. The prostate gland is a small soft structure about the size and shape of a walnut, which lies deep in the pelvis between the bladder... View Article

MRI Scan of the Rectum

What is an MRI scan of the rectum? Magnetic resonance imaging (MRI) uses a very strong magnet, and radio waves, to make detailed pictures of organs inside your body. MRI is considered to give the best (clearest) images or pictures of the tissues around the rectum, for identifying the extent of any disease. It makes... View Article

Traumatic Vascular Injury – Head & Neck

What is traumatic vascular injury to the head & neck? Traumatic vascular injuries can be either: A blunt injury to the chest, neck or head, which can result in damage to the blood vessels supplying the brain and can be caused by: forceful compression or pressure from a seat belt during a motor vehicle accident;...

Vacuum-Assisted Core Biopsy

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... View Article
