What is a CT scan?

To analyse structures inside your body, medical practitioners utilise computed tomography, generally known as a CT scan. A CT scan creates images of a cross-section of your body using X-rays and computers. It captures photographs of your bones, muscles, organs, and blood arteries in very tiny “slices” so that healthcare specialists may observe your body in exquisite detail.

How long does the test take?

A CT scan usually takes around an hour. The majority of that time is spent on preparation. The scan itself should take no more than 10 to 30 minutes. You can normally resume your normal activities after a healthcare expert advises it is safe to do so — usually after the scan has been completed and clear images have been verified.

How long does it take to get results?

The scan findings normally take 24 hours to arrive. Your scan will be reviewed by a radiologist, a physician who specialises in reading and interpreting CT scans and other radiologic images, and a report will be written to explain the results. Healthcare practitioners in an emergency situation, such as a hospital or emergency department, frequently receive results within an hour.

You will either have another visit or receive a call after a radiologist and your healthcare practitioner have evaluated the results. The results will be discussed with you by your healthcare professional.

Please inform the access center representative when you schedule your CT scan if you have had an allergic reaction to any contrast media. IV contrast will not be administered if you have had a severe or anaphylactic reaction to any contrast media in the past.These plans will be discussed with you in detail when you schedule your exam. Any known reactions to a contrast media should be discussed with your personal physician and you will likely need to take medication prior to the CT scan.

If your doctor ordered a CT scan without contrast, you can eat, drink and take your prescribed medications prior to your exam. If your doctor ordered a CT scan with contrast, do not eat anything three hours prior to your CT scan. You are encouraged to drink clear liquids. You may also take your prescribed medications prior to your exam.

Diabetics should eat a light breakfast or lunch three hours prior to the scan time. Depending on your oral medication for diabetes, you may be asked to discontinue use of the medication for 48 hours after the CT scan. If you have a CT scan with Johns Hopkins radiology, detailed instructions will be given following your examination.

All patients can take their prescribed medications as usual.
