What is Virtual Angiography?
Virtual angiography is an advanced imaging method used to examine the internal structure of blood vessels and blood flow in detail. This method is performed using a computed tomography (CT) scanner, producing three-dimensional images of the vessels. No catheter is inserted into the vessels during the procedure. Therefore, it is considered safer and more comfortable compared to conventional angiography. Virtual angiography can visualize not only the heart vessels but also those in the brain, neck, kidneys, and legs.
What is Virtual Angiography Used For?
Virtual angiography is performed to evaluate the structure of blood vessels and detect possible diseases. Its most common use is in the investigation of heart vessel diseases. Narrowing, blockages, or plaque formation in the coronary arteries can be seen in detail with virtual angiography. Additionally, aneurysms in brain vessels, narrowing in neck vessels, and problems in kidney vessels can also be detected with this method. It is particularly important for individuals experiencing chest pain, at risk of a heart attack, or showing suspicious signs related to vascular health.
How is Virtual Angiography Performed?
Before virtual angiography, a contrast agent is injected into the patient’s vein to make the vessels clearly visible. This agent enhances the visibility of blood as it passes through the vessels on the CT scan. The patient is placed inside the CT scanner, and during the imaging, they may be asked to hold their breath briefly to maintain regular heart rhythms. The scan itself only takes a few minutes, and the patient does not feel any pain. The obtained images are processed into three-dimensional views on a computer, allowing the specialist to examine the vessels in detail.
Difference Between Virtual and Conventional Angiography
The main difference between virtual and conventional angiography is the method of application. In conventional angiography, a catheter is inserted into the vessel, and the contrast agent is directly delivered into the vessels for imaging. This procedure is more invasive and is typically performed under local anesthesia. Virtual angiography, on the other hand, is done with a CT scanner, without the need for catheter insertion. Therefore, it is faster, more comfortable, and lower risk. However, conventional angiography can also be therapeutic; if a blockage is detected, procedures like balloon angioplasty or stent placement can be performed. Virtual angiography is purely diagnostic, providing images only.
Is Virtual Angiography Safe?
Virtual angiography is a modern imaging technique performed with CT technology and is highly reliable. The three-dimensional visualization of vessels allows detailed examination of heart, brain, neck, kidney, and leg vessels. Since no catheter is inserted, the risk of complications is lower than conventional angiography. The contrast agent used is generally safe, though caution is needed for patients with kidney disease. Radiation exposure is kept low, and the procedure is completed quickly. Therefore, virtual angiography is both safe and effective for diagnosis.
When is Virtual Angiography Preferred?
Virtual angiography is particularly used for early detection of vascular diseases. It is preferred for individuals experiencing chest pain, suspected narrowing or blockages in heart vessels, or at risk for brain aneurysms. Narrowing in neck vessels, blood flow issues in kidney vessels, and circulation disorders in leg vessels can also be detected with this method. For patients at risk of a heart attack, it offers a rapid and non-invasive alternative to conventional angiography. It is widely used as a diagnostic tool before making treatment decisions.
Who Should Not Undergo Virtual Angiography?
Virtual angiography may not be suitable for everyone. Patients with kidney failure are at risk because the contrast agent can harm the kidneys. Individuals with severe heart rhythm disorders, where heart rate cannot be controlled, may not achieve clear images. Pregnant women should avoid it due to radiation exposure. Patients allergic to the contrast agent should also not undergo the procedure. In such cases, the doctor may recommend alternative diagnostic methods.
Precautions Before and After Virtual Angiography
Before virtual angiography, patients should inform their doctor about existing medical conditions and medications. Drinking plenty of water before and after the procedure helps protect kidney function. Fasting may be required prior to the scan, so patients should follow the doctor’s instructions. Those with a history of contrast allergies should notify the medical team. No special care is usually required after the procedure, and patients can resume daily activities. However, drinking plenty of fluids for several hours post-procedure helps the body eliminate the contrast agent faster.
How Long Does Virtual Angiography Take?
Virtual angiography is completed faster than conventional angiography. Including preparation, the procedure typically lasts 20 to 30 minutes, while the actual scan usually takes only a few minutes. The time may increase slightly due to contrast injection, establishing a venous line, and processing images on the computer. Heart rate and breath control also affect the scan duration. Overall, virtual angiography is a quick and comfortable diagnostic method.
Where is Virtual Angiography Performed?
Virtual angiography is performed in the radiology departments of hospitals and medical centers equipped with advanced imaging technology. A CT scanner and contrast agent are required for this procedure. It is especially common in centers specialized in heart vessel diseases. The procedure is performed by a radiology specialist and technician team, and the images obtained are evaluated and reported by expert physicians.
Virtual Angiography Prices 2026
In 2026, virtual angiography prices vary depending on the healthcare facility, the technology of the devices used, and the region being scanned. Prices in private hospitals are generally higher than in public institutions. At private hospitals and imaging centers, virtual angiography costs range approximately from 8,000 TL to 15,000 TL. The use of contrast agents, reporting process, and specialist evaluation also affect the cost. Patients with health insurance may access the service at lower prices in contracted institutions. Overall, virtual angiography is a more accessible and comfortable option compared to conventional angiography.
Is Virtual Angiography Done on an Empty Stomach?
Virtual angiography is generally performed on an empty stomach. This reduces the risk of nausea or indigestion from the contrast agent. Fasting also helps provide clearer images of abdominal organs. Depending on the doctor’s instructions, patients are usually asked not to eat for 4 to 6 hours before the procedure. Drinking water is often allowed and even encouraged, as it helps eliminate the contrast agent from the body faster.
When Are Virtual Angiography Results Available?
Virtual angiography results are prepared after the images are evaluated by a radiology specialist. Although the scan is quick, detailed evaluation may take a few hours. In most centers, results are delivered to patients the same day. Depending on workload, this may take one or two days. In urgent cases, reports are prioritized and results can be obtained very quickly.
Does Virtual Angiography Clearly Show Heart Vessel Diseases?
Virtual angiography is highly reliable for evaluating heart vessel diseases. Narrowing, blockages, plaque formation, or changes in the vessel walls of the coronary arteries can be seen with high accuracy. Three-dimensional imaging allows detailed examination of vessel structures. However, in some cases, especially in severely calcified vessels, images may not be fully clear. Nevertheless, in most patients, virtual angiography is an effective and modern method for detecting heart vessel diseases.
Precautions After Virtual Angiography
Patients can generally resume daily activities after virtual angiography. However, because a contrast agent is used, it is recommended to drink plenty of water for several hours afterward to help the kidneys eliminate the contrast agent more quickly. No special care is typically required, though rarely, allergic reactions to the contrast agent may occur. If symptoms such as itching, rash, or shortness of breath develop, patients should contact their doctor immediately. Patients with kidney problems should follow post-procedure instructions carefully.
Is Virtual Angiography Performed in Public Hospitals?
Virtual angiography can also be performed in public hospitals equipped with advanced imaging devices. However, not all public hospitals have this technology. University and research hospitals in major cities usually offer virtual angiography. Patients need a referral from a doctor and must apply to the relevant department. Under the Social Security Institution (SGK), virtual angiography can be performed for free or at a reduced cost in approved cases at public hospitals.
