CT (computerised tomography) scans use X-ray equipment and a computer to create detailed two and three dimensional images of the inside of the body. They are used to look for signs of inflammation, disease or cancer and monitor many other medical conditions, including cardiac problems.
The Montefiore has invested in a Siemens SOMATOM CT scanner. This is one of the most sophisticated models available and provides a combination of high-end imaging and patient comfort. CT scans are safe and painless but involve exposure to some X-ray radiation (a similar amount to what you would receive naturally from the environment over three years). Siemens has led the way in developing technology to reduce the dose without compromising the image quality. The SOMATOM has a range of features that actively reduces the dose according to patient size and needs.
A CT scan is usually carried out as an outpatient procedure and we will aim to ensure it coincides with consultant appointments. Patients lie on a table that is moved into the scanner, a large circle with a central hole, like a doughnut. Images of the part of the body inside the ring are taken from all directions. Sometimes a dye may be used to make certain tissues show up more clearly. The dye is usually given as an injection into the arm and will be passed out naturally in the urine. The procedure can take from 10 to 30 minutes depending on the type of examination needed.
