What is a Uterine Fibroid Embolisation? Fibroids (also known as leiomyoma) are benign growths (non-cancerous) in the uterus or womb. They are common in fertile women and usually shrink after the menopause. The majority of fibroids are asymptomatic (without any obvious symptoms) and are either not known about by the individual or are found incidentally on examination or medical imaging....

What is an intracranial (brain) aneurysm? An intracranial (brain) aneurysm is an abnormal ballooning of the wall of an artery, which is a type of blood vessel carrying blood to the brain. The aneurysm is like a small sac and is localised, meaning it is limited to a small area, within the artery. In the brain, these vessels carry blood...

What is embolisation of head, neck and spinal tumours? Head, neck and spinal tumours (or growths) can occur on the coverings of the brain called meninges as well as anywhere in the head or neck region. These tumours can also occur in the back bone (spinal column). Structures inside the spinal column such as nerves can also give rise to...

What is a vertebroplasty? Vertebroplasty is a medical term which refers to the injection of a plastic cement, called polymethylmethacrylate (PMMA), into a vertebral body or small bones that make up the spinal column. Vertebrae in the spine are typically thick bone enclosing a hole for the spinal cord. They can become damaged through becoming weak with osteoporosis, from tumours...

What is a Spinal Cord Embolisation (AVM/DAVF)? The spinal cord is an extension of the brain that is situated inside the spinal column (or backbone), which connects the nerves from the brain to the rest of the body. This enables the brain to control movements of limbs and internal organs, such as the urinary bladder or bowel, and also to...

What is SAH Vasospasm Endovascular Treatment? Subarachnoid haemorrhage (SAH) is the release of blood into the space around the brain that contains fluid. It is within this space that the main arteries supplying blood to the brain are located before they enter the brain. SAH usually comes from a ruptured (burst) aneurysm on an artery. An aneurysm is a fluid-filled...

What is a whole body MIBI myeloma scan? A whole body MIBI myeloma scan is a nuclear medicine scan which involves the injection of a radioactive material or radioactive tracer called technetium-99m-Sestamibi, or MIBI for short.

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 to the heart and how...

What is a dual energy CT scan? Standard computed tomography (CT) scanners use normal X-rays to make cross-sectional ‘slice-like’ pictures or images of the body. A dual energy CT scanner is fairly new technology that uses both the normal X-ray and also a second less powerful X-ray to make the images. This gives dual energy CT additional advantages over standard...

What is chorionic villous sampling? Chorionic villous sampling (CVS) is offered from week 11 of pregnancy to women who are at a high risk of their foetus (unborn baby) being born with Down syndrome, or other chromosomal or inherited conditions. CVS also confirms the sex of the foetus, which can be important in identifying X-chromosome (female) linked inherited conditions. CVS...

What is a carpal tunnel ultrasound and injection? The carpal tunnel is located in the wrist, and is formed by the bones of the wrist and the transverse carpal (wrist) ligament. Through this tunnel pass the median nerve, flexor tendons (which help you to curl your fingers) and tendon sheaths (the coverings of the tendons). Carpal tunnel syndrome (also known...

What is carotid stenting? Carotid stenting is when a small, expandable, thin wire device (called a stent) is placed into one of the main arteries that carries blood to the front part of the brain (carotid artery), as it has become partially blocked with abnormal thickening of the artery wall called ‘plaque’. If the supply of blood to the brain...
