Ct neck scan: procedures and everything you need to know

Definition

What is a ct neck scan?

A CT (computed tomography) scan of the neck is a medical procedure that combines special X-ray equipment with computer imaging to create a visual model of your cervical spine. The cervical spine is the part of the spine that sits in the neck. Your doctor will recommend this test if you have recently had an accident or have neck pain. This examination can help accurately diagnose possible injuries to this part of your spine. This test is also called a neck CT scan.

When should I have a ct neck scan?

CT provides more detailed and faster images of the body. This test can help to check:

cervical spine birth defects in children
spinal problems, when an MRI of the spine cannot be used
injury to the upper spine
bone tumors and cancer
fracture
disc herniation and compression of the spinal cord

Precautions & warnings

What should I know before undergoing a ct neck scan?

Sometimes the CT test results can differ from other types of X-ray tests, magnetic resonance imaging (MRI), or ultrasound scans, because a CT scan provides a different view. Children who need a CT scan will need special instructions. If the child is too young to be quiet and doesn't move much or is afraid, the doctor will give you medicine (sedatives) to help him calm down. If your child is scheduled for a CT scan, talk to your pediatrician about the need for the scan, and the risk of radiation exposure to your child.

An MRI can provide more information than a CT scan of the spinal discs and spinal nerves. When a CT scan of the spine is done with a myelogram, it is called a CT myelogram. MRI of the spine is often done after a CT myelogram.

Process

What should I do before undergoing a ct neck scan?

If the examination involves using contrast dye, you will need to make certain preparations in advance. Be sure to tell your doctor if you have allergies or if you have diabetes. In rare cases, some people have allergic reactions to the dye. It can also cause negative reactions if you use certain drugs to treat diabetes. You should not eat or drink for four to six hours before the scan time if you are using a contrast dye.

It is highly recommended not to have a CT scan during pregnancy unless the benefits outweigh the risks. If you are pregnant, you need permission from your doctor before doing this examination. You will be asked to remove metal objects such as jewelry, piercings, glasses, hearing aids, or removable dental appliances. This can affect your CT scan results. Some machines have a weight limit; so be sure to tell your doctor if you weigh over 150 kg.

How is the ct neck scan process?

You will lie on a small table that can move into the center of the CT scan. Once you are in the scanner, the X-ray machine rotates around you. (Modern "spiral" scanners can perform checks without stopping). A computer creates separate images of body areas, called slices. These images can be saved, viewed on a monitor, or printed on film. A three-dimensional model of the cervical spine can be created by joining the slices together.

You must remain very still during the examination. Movement can cause blurry images. You may need to hold your breath for short periods of time. The scan process takes 10-15 minutes.

What should I do after undergoing a ct neck scan?

After this test, you can change your clothes back and go about your activities. If you need contrast dye for testing, you may need to drink plenty of water. This can help flush chemicals out of your body. The results from the CT scan will be available within 48 hours. Your doctor will review the images and determine what to do next. Depending on your results, your doctor may order additional scans, blood tests, or other diagnostic procedures to help get an accurate diagnosis.

If you have questions related to this test process, please consult your doctor for a better understanding.
