A CT scan is a medical tool that provides highly detailed images of the body. It is used for diagnosing injuries, guiding treatment plans and detecting diseases. Understanding what to expect before, during and after the procedure ensures you have a smooth experience while undergoing a CT scan.
What To Expect Before A CT Scan
You can start by arriving early for the CT scan. Wearing comfortable clothes is preferable. You might have to remove any jewellery or accessories that you might be wearing. The support staff at your chosen diagnostic centre might give you a hospital gown to wear.
There are certain steps that your radiologist might also take. They are:
1. Use of Contrast Material
The radiologist might highlight particular areas of your body. Some tissues, blood vessels and organs become easier to see, and the contrast is in the form of a dye. This contrast is injected into your vein through an IV Cannula. This dye might make you feel flushed. It can also give a metallic taste in your mouth. Some of the tests, like the barium scan, also require you to take oral contrast liquids. These tests are performed to check the intestines.
If you are receiving a CT scan with oral contrast, do not eat or drink anything 4 hours before your exam. Regarding water intake, follow the suggestions of your doctor or the radiologist/technician/nurse performing the examination.
2. Fasting Instructions
Do not eat solid foods four hours prior to the test. Fluids can be taken, like black decaffeinated coffee or tea, water and juice. Some abdominal CT scans require you to drink water. This helps in visualising the abdominal area better.
3. Medication Guidelines
Take all your prescribed medications along with you. You can also bring a list of your medications for the appointment. This list should include the name of the medication, dose and its frequency.
4. Instructions for Insulin-Dependent Diabetics
For insulin-dependent diabetics, insulin can be taken as prescribed. Make sure you inquire about whether fruit juices are allowed. Diabetes medications should also be taken as prescribed.
5. Disclosing Important Health Information
It should be disclosed beforehand if you have any kind of allergies. Serious health complications should also be revealed. Recent surgeries should also be discussed before the CT scan.
Any metal implants and electronic/medical devices on your body should also be mentioned. The possibilities of being pregnant should also be disclosed. If you have chosen the most reputed centres like Vijaya Diagnostics, you must disclose any health information that is relevant. This ensures that your scan is conducted accurately and safely.
What Happens During a CT Scan
In this section, we will explore what you can expect during the CT scan. It is crucial to understand the positioning and possible usage of contrast material. These are the situations you might experience during a CT scan:
1. Use of IV Contrast Agent
Multiple patients are given contrast agents intravenously during the CT scan. In certain cases, IV might be placed in your arm or hand when you are taken to the CT scan procedure room.
2. Appointment Duration
The entire CT scan appointment can last approximately 15 minutes. If the scan is being conducted with oral contrast, the duration can be taken as an hour and 15 minutes.
3. Procedure
You will be asked to lie down on a table throughout the duration of the test. The table will gradually be moved through the centre of the machine for a CT scan. The centre is shaped like a huge ring. You can also be asked to hold your breath for a short duration of time, typically for less than 15 to 20 seconds.
The scanner takes pictures of the area your doctor needs to examine. A CT scanner does not make much noise and is relatively quiet. When the scanning is over, the table moves out of the scanner. The entire procedure should take place under a trained professional. The person will guide you through the entire process. Whether you choose a CT scan in Hyderabad or any other city, you will have to go through this procedure.
What to Expect After a CT Scan
After a CT scan, you should know what to expect. It will make you feel more at ease after the procedure. We will now understand the follow-up steps you should know after the CT scan.
1. Post-Scan Monitoring and Instructions
Make sure that you are drinking fluids in abundance after the scan. It helps in flushing out the dye from your body.
2. Resuming Normal Activities
If your healthcare provider recommends it, you can resume normal activities after a CT scan.
3. Possible Side Effects from Contrast Material
If contrast dye was used during the CT scan, you might be monitored for a distinct period of time. This is due to reactions or effects of the contrast dye. Reactions can consist of rash, swelling, itching or difficulty in breathing. You can experience diarrhoea after the procedure if contrast was given by mouth.
4. Getting Your Results
It generally takes 24 to 48 hours to receive the results of your CT scan. Within an emergency setting, results can be provided by healthcare professionals within an hour. Once the result has been reviewed by your radiologist and doctor, you might have another appointment.
5. Follow-Up Recommendations
There are no clear recommendations on the number of CT scans one can have. If a child has undergone too many CT scans, it is recommended to include exposure to radiation as a part of the child’s medical history.
