What Is CT Scan?

The CT or computed tomography scan uses X-rays and the computer to display pictures of our internal organs, tissues, bones and blood vessels. These images are in thin slices, which enables medical professionals to have a discreet view of the body parts and diagnose better.

The CT scan happens in a rotating tunnel-like machine, allowing it to take X-rays from different angles. Later, the computer combines these images and delivers them as slices, cross-sections or even in a 3D form to help the doctors have a deeper understanding of the area. The CT scan is a minimally invasive procedure and takes a short time, probably 1 hr.

What is CT Scan with Contrast?

In a CT scan, dense body parts such as bones are easily visible, but the soft tissues aren’t, so the doctors use a CT scan with a contrast dye to highlight these parts and evaluate them properly. The dye, usually iodine or barium sulphate, emphasises blood vessels, tissues and other parts for better diagnosis. Doctors give the contrast dye to patients in either of the 3 ways-

Injection: If the doctor wants the gallbladder, liver, urinary tract or blood vessels to stand out during the CT scan, they inject the contrast dye on the arm. The dye travels through the veins and highlights these parts.

Oral: If it is the digestive tract or the pathway of food that the doctor wants to scan, the patient has to take a liquid mixed with contrast dyes.

Enema: If the intestine requires a diagnosis, doctors insert the contrast dye in the rectum.

  • Doctors ask the patient to drink the dye solution or administer it as required
  • Patients change into the hospital gown

During the Procedure

The CT scanners at Imaging Centres in Casula or elsewhere are tunnel-shaped machines. Patients lie on a table that is then pushed into this machine, and it takes X-rays from different angles.

Patients need to stay as still as possible since a slight movement can also cause a blurry picture which may be challenging to diagnose. After the scanning, the table moves back to its original position, enabling the patient to get up.

After the Procedure

After the procedure, the patients may resume their normal activities. However, the staff would inform them of precautionary steps if they had the contrast dyes.

When Do You Get the Results?

The radiologist reads and intercepts the test results from the imaging centre in Casula and generates a report that explains the results. Usually, one can avail the results in 24 hrs, but if it’s an emergency setting, they ensure to present the result in 1 hr.
