What is Computed Tomography (CT)?

Computed Tomography, commonly known as CT scanning, is a diagnostic imaging method that allows the detection of various diseases and pathological conditions. During a CT scan, the information obtained is processed by the system to create a complete, detailed image of the organs and body systems. This makes it possible to distinguish anatomical and physiological changes in the organs.

CT is a painless, non-invasive diagnostic method based on X-ray technology.

Which organs can be examined with CT?

CT can be used to examine:

• Organs of the chest

• Organs and systems of the abdominal and retroperitoneal cavities

• Pelvic organs

• Cardiovascular system

• Ear–nose–throat (ENT) structures

• Musculoskeletal system

CT is particularly effective for detecting benign and malignant tumors, even when they are small, and for determining their nature and extent.

How to prepare for a CT scan

No special preparation is required for most CT examinations.
Fasting is usually not necessary, and regular medications do not need to be withheld.
In general, no preparation is needed before CT scans of the head, neck, or chest.

What is CT Angiography?

For the evaluation of abdominal and pelvic organs, a CT angiography (CT with contrast) may be prescribed.
In such cases, some preparation is necessary.

If a contrast-enhanced CT scan is planned, the patient must first undergo a blood biochemical test to determine creatinine levels. Elevated creatinine is a contraindication for CT angiography.

If creatinine levels are within normal range, contrast material is injected prior to the scan, allowing for clearer and more detailed images.
The last meal should be taken 2–3 hours before the scan.
The contrast agent is typically eliminated from the body within 24 hours.

Contraindications for CT

There are no absolute contraindications for CT.
Relative contraindications usually relate to the use of contrast dye and include:

• Allergic diseases, especially bronchial asthma

• Allergy to iodine-containing solutions

• Renal insufficiency

• Pregnancy

• Hyperthyroidism

What happens during a CT scan?

Throughout the procedure, the patient lies on the examination table.
Depending on the organ being examined, the scan typically lasts 10–30 minutes.

CT and pregnancy

CT may be performed on pregnant women only when absolutely necessary.
