Computed Tomography (CT) Technology

Computed Tomography (CT) is an advanced radiological imaging method that uses X-rays to obtain very thin cross-sectional images of the internal structures of the body. These cross-sectional images are combined using computer technology, allowing detailed evaluation of organs, bones, blood vessels, and soft tissues.

CT plays an important role, particularly in situations where rapid and early diagnosis is required.

What are its features?

• Provides high-resolution and detailed cross-sectional images.
• Imaging can be performed in a very short time.
• Enables rapid diagnosis in emergency situations.
• When necessary, blood vessels and organs can be visualized more clearly using a contrast agent.
• Digital archiving and comparison with previous examinations are possible.
• Low-dose protocols are used with modern CT scanners.

In which cases is it used?

• Cardiovascular diseases (CT angiography)
• Head trauma and suspected brain hemorrhage
• Lung diseases, and evaluation of nodules and embolisms
• Diseases of the liver, pancreas, kidneys, bladder, and peritoneum
• Diseases of the abdominal and pelvic organs
• Investigation of cysts and infections
• Tumor diagnosis and staging
• Kidney stones
• Trauma and multiple injuries

Coronary CT Angiography (Virtual Angiography) is a rapid and detailed CT examination of the blood vessels that supply the heart. Unlike conventional angiography, it does not require access through the groin; the scan is performed using a contrast agent administered through a vein in the arm, and hospitalization is not required. For optimal image quality, heart rate control and compliance with brief breath-holding instructions are important. Patients are generally asked to fast for 4–6 hours before the appointment and avoid caffeine-containing beverages such as tea and coffee for 24 hours. When the contrast agent is administered, a brief sensation of warmth or a metallic taste in the mouth may occur; these effects usually disappear within a short time.
