What is a CT Scan?

A CT scan, also known as a computed tomography scan, is an imaging technique that uses X-rays to produce detailed images of the internal organs, bones, and tissues of the body. The images generated are cross-sectional, meaning they display a 3D view of a specific area of the body.

CT scan stands for computed tomography scan.

How Does CT Scan Work?

During a CT scan, a patient lies on a table that slides into a donut-shaped machine. The machine takes several X-ray images from different angles, which a computer processes to create a 3D image of the area being scanned. The process is painless and usually takes around 15-30 minutes.

Types of CT Scans

There are various types of CT scans, including:

  • Abdominal CT Scan
  • Chest CT Scan
  • Head CT Scan
  • Pelvic CT Scan
  • Virtual Colonoscopy

Why do we need CT Scan?

CT scans can diagnose several medical conditions, including:

  • Cancer
  • Heart Disease
  • Brain Disorders
  • Trauma
  • Bone Fractures
  • Internal Bleeding
  • Lung Conditions

Risks of CT Scan

CT scans use ionizing radiation, which can increase the risk of cancer if done frequently. Additionally, some patients may have an allergic reaction to the contrast dye used during the scan.

Benefits of CT Scan

CT scans offer several benefits, including:

  • Non-invasive
  • Painless
  • Quick
  • Accurate
  • Can detect conditions at an early stage

CT Scan vs. MRI

CT scans use X-rays to produce images, while MRI (magnetic resonance imaging) uses magnetic fields and radio waves. CT scans are faster and better suited for diagnosing bone and lung conditions, while MRIs are better suited for soft tissue and joint disorders.

Preparing for CT Scan

Before a CT scan, patients may need to:

  • Avoid eating or drinking for a few hours
  • Remove jewelry and metal objects
  • Wear comfortable, loose clothing

During the CT Scan

During the CT scan, the patient lies on a table that slides into the machine. The technician may ask the patient to hold their breath for a few seconds to avoid blurry images.

After the CT Scan

After the scan, patients can resume normal activities unless they received sedation or a contrast dye, in which case they may need to rest for a few hours.

Interpretation of CT Scan Results

A radiologist will interpret the results of the CT scan and send them to the patient’s doctor. The results may take a few days to become available.

How to Get a CT Scan

Patients can get a CT scan by getting a referral from their doctor and scheduling an appointment with a radiology facility.


A CT scan is an essential imaging tool that helps diagnose a wide range of medical conditions by creating detailed images of the body’s internal organs, bones, and tissues. Understanding what a CT scan is, how it works, its benefits, and risks can help you prepare for the procedure and make informed decisions about your healthcare.
