Chest/Lungs

A detailed scan that captures cross-sectional images of the lungs, heart, and chest structures. It helps detect conditions like nodules, tumours, or other abnormalities that may not appear on standard X-rays.

What Is a Chest CT Scan?

A Chest CT scan—also known as a CT chest scan or CT scan of the chest—is a specialized imaging test that uses computed tomography to generate detailed, cross-sectional images of the lungs, heart, airways, blood vessels, and bones within your chest. Unlike a traditional chest X-ray, a chest CAT scan provides more precise information, helping to detect abnormalities that might be missed on a standard X-ray.

This scan is especially useful for examining lung structures and can reveal even small nodules or tumors that are not visible through other imaging methods.

Why You Might Need a CT Scan of the Chest or Lungs

A CT scan of the lungs or chest may be recommended if you're experiencing symptoms like:

• Persistent cough
  
• Chest pain
  
• Difficulty breathing
  
• Unexplained weight loss
  
• Coughing up blood
  

If you are experiencing any of the above or any other concerning symptoms, see your doctor.

It’s commonly used for evaluating infections, lung diseases, and assessing injuries after trauma. If your doctor suspects conditions such as pneumonia, tuberculosis, or interstitial lung disease, they may recommend a CT lung scan. Additionally, it plays a crucial role in follow-up imaging for patients with known abnormalities found in previous tests, such as an X-ray lung cancer image.

What Can a Chest CT Scan Detect?

A chest scan can help detect:

• Lung nodules and tumors
  
• Infections and inflammation
  
• Blood clots in the lungs (pulmonary embolism)
  
• Pleural effusion (fluid around the lungs)
  
• Lymph node enlargement
  
• Structural issues like hernias or airway abnormalities
  

These findings are vital for diagnosing both benign and serious conditions. For example, an abnormal lung CT scan may reveal subtle signs of early-stage lung cancer, which may be missed on X-rays.

CT Scan for Lung Cancer: When and Why It's Used

A CT scan for lung cancer is often used in high-risk individuals—typically those over 50 with a history of heavy smoking. A lung CT scan is preferred over X-rays because it can detect smaller nodules with higher accuracy.

CT lung cancer screening is now a standard recommendation in many countries for early detection. It can be part of a proactive health strategy and is often performed yearly for those with significant risk factors.

When compared to an X-ray lung cancer image, a CT scan lungs test provides significantly clearer and more actionable results, improving chances of early detection and treatment success.

Contrast vs Non-Contrast CT Chest Scan

A contrast dye is injected into a vein either before or during a chest scan to help enhance the clarity of the images. This dye highlights blood vessels, tumors, and inflamed tissues more clearly.

• Contrast CT chest scan is useful for evaluating tumors, blood flow, and infections.
  
• Non-contrast CT chest scans are typically used to evaluate lung nodules, chronic lung disease, or follow-up imaging.
  

Your radiologist or doctor will determine which type is best depending on your condition.

What Does an Abnormal Chest CT Scan Mean?

An abnormal chest CT scan does not always indicate a serious condition, but it does suggest that something within your chest needs further evaluation. Potential causes include:

• Infections (e.g., pneumonia, tuberculosis)
  
• Benign or malignant tumors
  
• Fluid accumulation
  
• Lung scarring
  
• Enlarged lymph nodes
  

Your doctor may recommend additional tests such as a biopsy or follow-up imaging to determine the cause of the abnormality.

CT Chest Scan Procedure: What to Expect

The procedure for a CT chest scan is quick, painless, and usually takes about 10–20 minutes. Here’s what typically happens:

1. You’ll lie on a motorized table.
   
2. The scanner rotates around your chest to take images.
   
3. If contrast is needed, a dye will be injected through a vein in your arm.
   
4. You'll be asked to hold your breath briefly during image capture.
   

The entire CT scan chest process is designed for minimal discomfort and maximum accuracy. The images are then reviewed by a radiologist and shared with your referring doctor.

How Long Does a Chest CT Scan Take?

Typically, a lung or chest CT scan takes between 10 to 30 minutes, with the majority of that time spent on preparation. The actual imaging process generally only takes a few minutes, especially if contrast dye is involved.

Cost of Chest and Lung CT Scans

The cost of a chest CT scan can vary depending on your location, whether contrast is used, and whether the scan is done at a private facility or through a public healthcare system.

In the UK, private CT lung scans range from £250 to £700. Pricing may be higher if additional analysis or contrast is required. Despite the cost, early detection through a CT chest scan can save lives and reduce long-term treatment expenses.
