What to Expect During a CT Scan

When you arrive for a CT scan, you’ll be asked to lie down on a table. The table will move through the CT scanner, which is a large machine with a ring-shaped opening. The table will move through the opening as the X-rays are taken.

During the scan, you’ll be asked to remain still. The scan usually takes between 10 and 30 minutes, depending on the type of scan being done.

Types of CT Scans

There are several different types of CT scans that can be used to diagnose medical conditions. The most common types of CT scans are:

Abdominal CT Scan: An abdominal CT scan is used to create images of the abdomen. It can be used to diagnose conditions such as appendicitis, kidney stones, and gallstones.
Brain CT Scan: A brain CT scan is used to create images of the brain. It can be used to diagnose conditions such as stroke, brain tumors, and head injuries.
Chest CT Scan: A chest CT scan is used to create images of the chest. It can be used to diagnose conditions such as lung cancer, pneumonia, and emphysema.

Risks of a CT Scan

CT scans are generally safe, but there are some potential risks associated with the procedure. These risks include:

Exposure to radiation: CT scans use X-rays, which can expose you to radiation. The amount of radiation you’re exposed to during a CT scan is usually very small, but there is still a risk of radiation-related side effects.
Allergic reactions: Some people may have an allergic reaction to the contrast dye used during a CT scan.
Pain: Some people may experience pain or discomfort during a CT scan.
