Our scans and imaging services were made with patients in mind, providing a full array of imaging and scanning services at times convenient for all schedules. We know that if you or any member of the family need a diagnostic examination, and choose to have it done sooner then we canprovide same day, add-on appointments and extended weekday 9am – 9pmand weekend 10am – 2pm hours forour patient’s convenience. We use state of the art scanning and imaging technology which is subject to strict regulatory standards.
Scanning and imaging technology shows the healthcare provider the inside of your system. An ultrasound uses sound waves that pass through your body. It can show your internal organs and their size as well as the location of any abnormalities. It is safer than a mammogram or X-Rays, as no radiation is involved, and also gives better and clearer pictures of breast tissue and soft tissue structures throughout the body.
Gives clear pictures of bones as well as soft tissues, which an ordinary X-ray test does not show; e.g. organs and large blood vessels, muscles, nerves, and the brain. Frequently performed CT scans are of the brain – in the majority of cases to determine the cause of a stroke.It is also used to pinpoint the exact site of tumours prior to radiotherapy and/or to find the right place to take tissue samples (biopsies).
You will need to remove any metal objects from your body, such as jewellery, hair clips, etc. and wear loose clothing without metal zips, studs, etc.
Instructions will be given to you by the CT department. Dependingon which part of your body is being scanned: the aim is to block out X-rays going through some tissues and in others help give a better contrast and pictures between the different organs and tissues that necessarily need investigating.
CT scans are painless but you need to stay as still as possible, to avoid the scan pictures being blurred. Conventional CT scans take from 5-30 minutes, depending on which part (or parts) of the body is being scanned. Modern CT scans (helical CT scans) take less than a minute and also use less radiation. However the reports outlining the findings do take a little longer.
If a CT scan with contrast is arranged, you might be advised to not to drink or eat for a couple of hours before the test. You may also be given a steroid injection prior to the test if you are susceptible to contrast to avoid a reaction. (People who have areaction to the contrast dyeis rare.)
A contrasting dye is sometimes injected into the bloodstream via a vein in your arm. Depending on what is being investigated. You may be aware of a flushed cold feeling initially and an odd taste in your mouth, but this soon goes.
If you need an injection of contrast it may be necessary to stop certain medicines before the procedure. This may apply to diabetics taking metformin. If this is you then our doctor will give you instructions about what you need to do.
Sometimes a special contrast medium drink is usually requiredbefore an abdominal and/or pelvic scan. This helps highlight the stomach and bowel more clearly. Or a small amount of fluidmay be put into your back passage (rectum). Women may be asked you to insert a tampon into the vagina for a pelvic scan.
An MRI scan uses a strong magnetic field and radio waves to create pictures on a computer screen. It can show tissues, organs and other structures inside your body. MRI scans do not use X-rays so the concerns associated with X-rays and CT scans (which use X-rays) are not associated with MRI scans.
It is regularly used to take detailed pictures of the brain and spinal cord; to assess joint disease; soft tissue tumours and even torn ligaments which are detected using an MRU and useful in assessing sports injuries.
An MRI produces clearer images than computerised tomography (CT) and is the first-choice investigation for brain tumours which shows hard-to-reach areas of the brain. Itis also the best choice for many other conditions, including multiple sclerosis, stroke, Alzheimer's diseaseand epilepsy.
MRI is a non-invasive assessment of inflammatory bowel diseaseand bowel tumours and problems in the liver and pancreas.
MRA,magnetic resonance angiography generates pictures of the arteries looking for abnormal narrowing or dilatations in blood vessel walls (those at risk of bursting). It isalso used to assess the arteries of the neck, brain, the renal arteries, thoracic and abdominal aortic arteries, and arteries in the legs. Sometimes it is used to assess congenital heart disease.
It uses extremely strong magnets, so people with certain types of medical implants cannot be scanned. Medical devices containing metal in them can potentially move,or the magnet affects their function.
Therefore, you should be asked if you have any medical devices in your body. At the scanning centre you will be asked to fill in a safety questionnaire about these things prior to the scan. We can telephone before to let them know and whether this will affect your ability to have an MRI/MRA, however we do stress that you should remind them yourself at the time of your scan. If you have forgotten, do not worry we can rearrange a different scan for you. It is more important to be safe.
The following may help to remind you of the type of things radiographers need to know about:
It is important for the radiographer to know if you have any metal fragments lodged in your eyes or body. You may need an X-ray before your MRI scan, just to make sure you are safe to enter the scanner.
If you are pregnant it is possibly best not to have an MRI scan unless it is urgent. Although it is believed to be safe, the long-term effects of strong magnetic fields on a developing foetus are not yet known.
The scans and imaging results are assessed by the radiologists, a doctor who has advanced knowledge in reading scanning and imaging tests. Then he/she will send a report to our doctor detailing what the results are and what might be an issue.
It can take fromtwelve hours to three days,depending on what is being investigated, to get the results as mentioned above. Usually, the doctor who ordered your scan will call you with the results orinvite you in to review them in person. If the scanning and imaging were done due to an emergency, the result is fast tracked in most cases.
We collaborate with an imaging service which makes use of open MRI technology that performs the scanning in a less confined space that can lessen claustrophobia and anxiety.
