CT SCAN

Computerised tomography or CT scan as it is called combines data from various X Rays to provide a detailed image of the body structures. It produces as 2-dimensional slice image or section of the body. The data can be converted into a 3-dimensional image as well. CT Scan images are helpful in assisting doctor to diagnose certain conditions.

Trauma

CT scans are commonly used to assess internal injuries caused by trauma, such as fractures, bleeding, and organ damage.

Cancer/ Stroke/ Heart Disease

CT scans help in the detection, staging, and monitoring of various types of cancer, allowing healthcare providers to plan appropriate treatment strategies.

Infections and Inflammatory Conditions

CT scans can identify infections, abscesses, and inflammation in different parts of the body, aiding in diagnosis and treatment.

Vascular Disorders

CT angiography (CTA) is a specialized form of CT scan used to visualize blood vessels and diagnose conditions such as aneurysms, arterial stenosis, and blood clots.

Biopses

To guide physicians and surgeons during biopses, fluid drainage and other treatment.

Preparing for a CT Scan (uni scans)

Clothing and Jewelry

You may be asked to remove clothing and jewelry that could interfere with the imaging process.

Contrast Agents

In some cases, a contrast dye may be administered orally, intravenously, or rectally to enhance the visibility of certain structures or abnormalities.

Medical History

Inform your healthcare provider about any allergies, LMP, medical conditions, or medications you’re taking, as they may affect the CT scan procedure.

Risks and Considerations

While CT scans are generally safe and well-tolerated, it’s important to be aware of potential risks, including:

Radiation Exposure

Although the radiation dose from a single CT scan is relatively low, repeated or unnecessary scans may increase the cumulative risk of radiation-related health effects.

Contrast Reactions

Some individuals may experience allergic reactions or adverse effects from contrast agents used during the scan.

Pregnancy and Radiation

Pregnant women should inform their healthcare providers before undergoing a CT scan, as radiation exposure may pose risks to the developing fetus.

Reasons for a Coronary CTA

Patients at risk for coronary artery disease should have a coronary CTA to check for early signs of the disease, and help prevent permanent damage. This test is often effective in identifying problems in patients with no symptoms, and is also helpful in diagnosing coronary disease in patients with abnormal symptoms. Additional reasons that a physician may order a coronary CTA include:

  • To investigate a possible aneurysm
  • To examine blood vessels for atherosclerosis
  • To find abnormal blood vessel formations in the brain
  • To identify damaged blood vessels
  • To identify blood clots that may have traveled
  • Evaluate tumors fed by blood vessels
