The CT Radiographer
Hello, I am one of the professionals who is responsible for checking that you are the correct patient and then explaining the procedure and performing it. My training was initially as a radiographer and I have subsequently spent specialist time training in CT scanning. I work closely with the radiologists. It is my responsibility to ensure that you have had the correct preparation and often I will ask you a number of questions to ensure that it is safe to proceed. When we enter the scanning room, I will ask you about clothing, to ensure that there are no metal objects that may interfere and position you on the scanning table. The table moves quite quickly through the scanner and therefore you should be reassured that you will only be within the narrow tube for a very short period of time. I will be able to see you from the scanning position, either through a television link-up or directly, the whole time that you are in the scanner. I will also be able to hear you and talk to you to explain what is happening and what is needed from you. As many of the scans require injections of dye, either myself, the radiologist or one of the other members of staff will place a small needle in your hand or arm. When the injection takes place, it often gives people a warm sensation, as described above. Sometimes people also sense a metallic taste in their mouth. These sensations are all normal and not a reaction to the dye, they will pass within 20 or 30 seconds. The scans are relatively quick, taking between 10 and 20 minutes to perform. You will then be helped off the table and may be asked to remain in the department for a short time, to ensure that there have been no problems with the injection.As the radiographer, I co-ordinate the scanning and ensure that the correct areas have been covered that were requested by the original doctor. The computer processes all the information and then the radiologist, when this is complete, will report the scan. As there can be anywhere up to over 1,000 images, this takes some time and therefore the reports are not available immediately. The doctor who initially referred you should receive the report within the next few days or up to a week.
