What is CT?
CT stands for Computed Tomography. CT combines X-rays with computer technology to create accurate, detailed diagnostic images. Electronic sensors help detect the X-rays that pass through your body to create images used by the doctor to make an in-depth evaluation. Contrary to popular belief, CT testing is non-invasive, painless and relatively fast. Although CT exam is one of the most regular medical imaging procedures, it will be in your best interest to inform your doctor if you are pregnant, asthmatic, diabetic and taking metformin, breastfeeding or suffering from suffering from acute/chronic renal failure.
Why is a CT exam performed?
You will be made to undergo a CT exam in case of an injury or if your doctor suspects any medical condition that cannot be detected easily with
physical examination. CT makes use of X-rays to obtain detailed pictures of internal structure of your body which can't be obtained by other imaging
technologies like X-ray or ultrasound. It helps your doctor make a well-informed diagnosis and give you the best care.
What can you expect during a CT scan?
Depending on the part of the body to be scanned, you will be given instructions by your doctor. Unless told otherwise, you can eat and drink normally before and after the scan. However, if you are advised for a contrast injected scan, you may require 4-6 hours fasting prior to the examination. The CT scanning procedure usually lasts for 5-10 minutes in which the actual exposure time is only few seconds.
What is being injected for the scan and why?
You may need a contrast medium injection into your arm before the scan. This is necessary to highlight certain organs or vessels more clearly. However, with Philips Ingenuity CT the process is much safer as the injected contrast dosage can be lowered by up to 80% depending on the kind of scan. You will be asked about any allergies especially from iodine based products or Shellfish and any other medical conditions before the infusion. You may experience a warm sensation or metallic taste in the mouth for a couple of seconds after contrast. It is recommended you drink plenty of fluid after the scan if you have had contrast.
