A computerized tomography (CT) scan, sometimes referred to as computerized axial tomography (CAT) scan, is a type of imaging test that uses a combination of sophisticated X-ray technology and a computer to create cross-sectional images of the body. The images produced show more detail than a regular X-ray and can show blood vessels, bones, and soft tissues in various parts of the body. The scan can help your doctor detect a variety of diseases and conditions. In a full-body CT scan, the test is used to visualize virtually all parts of the body.
A full-body CT scan can analyze three major areas of the body: the heart, the lungs, and the abdomen. This test is commonly used on those who already have cancer, to see if it has spread to other parts of the body. It is also helpful in an emergency situation to help your doctor examine a major injury. Besides, the test can be used to:
Diagnose disorders of the muscle and the bone, such as fractures and bone tumors
Pinpoint the exact location of an infection, blood clot, or tumor
Detect and monitor diseases and conditions that may be present in your body
Detect internal bleeding and internal injuries.
Your doctor may also recommend a full-body CT scan if you are at a high risk of lung cancer.
During a full-body CT scan, you will have to lie flat on your back on a motorized table that can slide through the doughnut-shaped CT scanner machine. Straps, pillows, and a special cradle may be used to help you stay in the correct position and remain still during the exam. In some cases, a contrast material may be used. It will be injected through an intravenous line (IV) or swallowed.
To determine the correct position for the scans, the table will move quickly through the scanner. Then, during the actual CT scanning, the table will move slowly through the machine and it may take several passes. When the motorized table moves you into the machine, the X-ray tube and detectors will rotate around you. Several images of thin slices of your body are taken in each rotation. The images are then sent to a computer, where they are combined to
The radiographer will operate the machine from a separate room. They can see and hear you, and you will be able to communicate with them during the scan via intercom. They may ask you to hold your breath at certain parts of the scan because you need to stay completely still. Any motion, including body movements and breathing, can blur the scan images. The radiographer may also lower, raise, or tilt the table to create the correct angle for the X-rays.
No anesthesia is involved in a full-body CT scan as it is not painful. However, children who cannot stay still may be sedated.
You may be allowed to leave the hospital on the same day as your full-body CT scan. However, since the results will not be given to you immediately, it is advisable that you stay in Lebanon for 5 to 7 days, or until the results are ready. Once the results are ready, you will have to attend a follow-up appointment to discuss them with your doctor.
Full-body CT scans do not require any recovery time. You can return to your daily activities, go to work, drink, drive, eat, and drink as normal straight away.
If a contrast material is used, you will have to drink lots of fluids to help your kidneys flush out the contrast material from your body. If not, there are no restrictions or special aftercare following the procedure.
A full-body CT scan has the potential to be inaccurate. A cancer diagnosis based on a CT scan has up to 30% inaccuracy rates. In addition, the procedure is not recommended for those without symptoms.
A full-body CT scan carries some potential risks. During the procedure, your body will be exposed to ionizing radiation. While low doses of radiation in the procedure have not been revealed to cause any harm in the long-term, much greater doses may slightly increase your risk of cancer. The procedure can also harm unborn babies. Therefore, make sure to tell your doctor if you are pregnant.
In some cases, the contrast material can cause allergic reactions, which may result in a rash or itchiness.
Magnetic Resonance Imaging (MRI) scans is the main alternative to a full-body CT scan. MRI scans are currently being evaluated for their possible value in screening. One major benefit of the procedure is that they do not expose you to ionizing radiation. However, they tend to be more expensive than a full-body CT scan.
Before a full-body CT scan, you may experience unexplained symptoms or have a high risk of developing certain diseases. After the procedure, your doctor should find out if there are any abnormalities present in your body. If they do find an abnormality, they may order more imaging procedures to confirm their diagnosis or discuss the best treatment/management plan for you.

Lebanon, a country on the eastern shore of the Mediterranean Sea, is one of the smallest sovereign states. The country boasts a fascinating mixture of the Middle East and the West, Christianity, and Islam, and tradition and modernity. It has everything from golden beaches and World Heritage Sites to energetic nightlife and delicious cuisine. Among other countries in the Middle East, Lebanon appears to be one of the most popular medical tourism destinations. Over 10% of the tourists visiting the country, particularly from neighboring countries, come to receive medical care. Many hospitals and clinics in the country are accredited to the ISO:9000 standard and offer world-class specialist services in spine treatment, orthopedics, organ transplant, and other complex surgeries, as well as advanced cancer treatments. Cosmetic and reconstructive surgery are also popular.
Beirut, the capital and largest city of Lebanon, is filled with historic landmarks and natural wonders. The most famous attractions in the city are the National Museum of Beirut, the Corniche and Pigeon Rocks, Sursock Museum, and Mohammed Al Amin Mosque. Many people also come to Lebanon to visit the port town of Sidon. Once a rich and thriving Phoenician city, it is dotted with historical monuments and ancient remnants, particularly in its Old City. Other popular cities include Tripoly, Baalbek, Byblos, and Tyre.
Lebanon has four seasons: winter (December to March), spring (April to May), summer (June to September), and autumn (October to November). Winter is the rainy season with high precipitation levels and cool temperatures. It is snowy in the mountains, but in some places, such as Beirut, it just rains during this season. Summer is hot, sunny, and dry, and can get very humid in cities located close to the sea. In the summer, the average temperatures are around 28°C to 30°C. Spring and autumn are both warm and pleasant.
The main international airport where visitors fly into and out of Lebanon is Beirut–Rafic Hariri International Airport, which is the only operational commercial airport in the country. It serves international flights to numerous major cities across Europe and the Middle East, including Moscow, Paris, London, and Dubai. Given the small size of the country, there are no internal flights. Intercity buses and minibus are available and have an extensive network, especially in coastal areas. The best way to get around the country is by hiring a car (with a driver) or by using intercity taxis.
All visitors need to obtain a visa to enter and stay in Lebanon unless they come from one of the seven visa-exempt countries (including Kuwait, Bahrain, Qatar, Saudi Arabia, Oman, the United Arab Emirates, and Jordan). Citizens of 81 countries, including all EU countries, Australia, China, Canada, and the United States, are eligible for a visa on arrival for a maximum stay of 30 days. A conditional visa on arrival is available for citizens of 15 countries, including Algeria, Libya, Iraq, and Yemen.
