A CT scan, also known as a computed tomography (CT) scan, uses special x-ray equipment to obtain image “slice” data from various angles around the human body, which are processed to show a cross-section of selected body tissues and organs.
High quality images are acquired at sub-millimetric resolution. This allows a three-dimensional analysis of the organs.
The examination is painless and usually lasts between 5 and 15 minutes. The radiographer will receive you and accompany you to your personal changing room. After checking for contraindications, you will be asked to remove clothing or metal items (jewellery, belt, telephone, removable prosthesis, etc.) depending on the type of examination requested. If necessary, your CT scan may require an intravenous injection of an iodinated contrast agent. At this time, a small-calibre venous line will be placed. The operator will then accompany you to the examination room and help you to position yourself on the examination table (in most cases, you will lie on your back). During the examination, please follow the instructions carefully. You may be asked to hold your breath for short periods of time.
It is important to notify us as soon as you arrive or when you make an appointment:
For more information, see our Scan Fact Sheet.
At the Medical Imaging Facility (GIE) of the University Hospital Institute (IHU) in Strasbourg, we have a Siemens Dual Source CT Scanner, the result of cutting-edge technology giving access to ultrafast, high-resolution imaging.
Special case: your doctor has prescribed an enteroscanner: this examination takes approximately 15 minutes and allows a detailed, three-dimensional visualization of the small intestine. Fasting is required. You will be asked to drink approximately 1L of a liquid (which will be prescribed to you) which will slightly distend your bowel. A small venous line will be placed for contrast injection during image-acquisition. Scheduling your appointment should allow sufficient time for preparation.
For your MRI, please bring :
Before you undergo the examination, you will be asked to fill out an MRI screening form.
Preparation
There is no special preparation for routine examinations. Fasting is not required. However, for certain specific exams, you will be given specific preparation instructions when making your appointment.
How much time will I spend at the Medical Imaging Facility (GIE)?
You will need to allow approximately one hour between your arrival at our Imaging Centre and your departure. Naturally, your waiting time may vary depending on the number of people, especially if there are emergencies. The scan itself takes around 5 to 15 minutes.
In Case of an Emergency
During the Medical Imaging Facility’s opening hours, depending on the degree of urgency, radiologists can accept where possible, to perform your MRI in an urgent/semi-urgent situation: please do not hesitate to contact our secretariat.
