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 Costa Rica 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.

Costa Rica is a tiny country in Central America, bordered by Panama, Nicaragua, the Caribbean Sea, and the Pacific Ocean. This country is generally regarded as having the most democratic and stable government of all the Central American countries. It charms its visitors with unspoiled beaches, lush rainforests, a plethora of wildlife, and steaming volcanoes. Besides its breathtaking landscape, Costa Rica is also famous for its healthcare. Tens of thousands of medical tourists come to this country to take advantage of its world-class yet inexpensive medical care. Most of the medical procedures in the country are 40% to 50% cheaper than in the United States or Europe. Cosmetic surgery and dentistry are the most sought-after procedure, but a growing number of foreign patients also come for orthopedic treatment, bariatric surgery, and eye surgery.
Surrounded by volcanoes and green hills, San José, the capital and largest city of Costa Rica, has one of the most spectacular settings in the world. This laid-back and pleasant capital is filled with colonial mansions that have been converted into contemporary galleries, amazing food, and vibrant nightlife. The most popular attractions in this city are Museo de Jade, Teatro Nacional, Museo Nacional de Costa Rica, and Mercado Central. Those who want to relax under the sun usually visit Tamarindo, which is famous for its beaches. Here, visitors can visit Las Baulas National Marine Park, go rafting in the Colorado River, or relax in Playa Tamarindo.
Due to its close proximity to the Equator, Costa Rica is a tropical country with two seasons: the dry “summer” season and rainy “winter” season. The dry season, from January to April, is warm and pleasant. Rain is very unlikely to fall during this season, even in the rainforests. The rainy season, sometimes called the “green season,” is hot and humid. Rain usually falls in the afternoon and evening, while the mornings are often sunny. On the Caribbean coast, rainfall is spread out throughout the year, but it gets far less rain in September and October.
Juan Santamaría International Airport is the main international airport in Costa Rica, located in San José. It has various flights to domestic and international destinations, including Toronto, Mexico, New York, and London. Affordable domestic flights between San José and popular destinations are the fastest way to get around and handy for accessing the more remote areas. Buses are reasonably priced and have an extensive network, but they can be slow. Private and shared shuttles are available, the best way to get around is, however, by renting a car as it gives more flexibility and allows you to access more remote destinations.
Everyone who wants to visit and stay in Costa Rica is required to have a passport unless they are a citizen of one of the visa-exempt countries. The visa-exempt countries include EU countries, the UK, the US, Australia, Russia, and several other nations. Citizens of other countries not listed in the visa exemption agreement need to apply and obtain a visa before visiting.
