CT Head/ Neck/Chest
CT (Computed Tomography) scan, also known as a CAT Scan, provides the radiologist with detailed images of the organs and deep parts of the human body. It uses a rotating x-ray device and a computer to create an image through the human body, similar to how a slice of bread shows us what the inside of a loaf of bread looks like.
The patient is placed on a slowly moving CT table and the patient moves through the scanner, which is designed more like a doughnut than a tube and is only 36 inches deep. Most claustrophobic patients find the visit to be very manageable. The total time where the patient is engaged with the scanner itself is about 5 minutes.
All patients should expect that the radiologist, who will interpret the exam, might suggest the use of x-ray dye or x-ray contrast material, which is given through a small IV, into the bloodstream. The technologist will explain the specific requirements for your scan prior to your study. Please feel free to ask any questions.
If this scan is being performed because of an abnormality found on another imaging study, the patient should bring those films and the report with them at the time of their CT scan.
Preparation:
- No food or drink for 4 hours prior to the exam. Medications may be taken with a small amount of liquid up to exam time. Patients who are diabetic can call the CT Department if they need to eat prior to the study due to insulin, etc.
- Patients who are diabetic and on Glucophage should not take Glucophage on the day of the exam and should consult their physician before restarting the medicine.
- Patient will be required to remove clothing or jewelry, which may interfere with the CT Scan such as earrings, dentures, necklace, glasses or hairpins.
Precautions:
- Patient should inform the technologist if they have a history of allergies (especially to previous contrast injection, medications, or shellfish), asthma, diabetes, kidney problems, thyroid problems, or heart condition. Please inform the technologist if you are or may be pregnant.
