A CT scan (Computed Tomography), also popularly known as a CAT scan or scanner (TAC in Spanish), is one of the most widely used and decisive diagnostic imaging tests in modern medicine. It allows for a precise three-dimensional X-ray of the inside of the body in just a few seconds.
Knowing what a CT scan is and what it is used for helps you face the test with complete peace of mind. This technology uses X-rays combined with advanced computer processing to provide detailed cross-sectional images or “slices” of bones, internal organs, blood vessels, and soft tissues.
What is a CT scan done for and what is its purpose?
Unlike a conventional X-ray (which provides a flat two-dimensional image), a CT scan allows the examined area to be reconstructed in 3D.
Why a CT scan is performed:
- Precision diagnosis: allows the identification of very small lesions, infections, or anatomical abnormalities that are not visible in other tests.
- Treatment planning: essential for surgeons or oncologists to plan specific interventions or treatments.
- Guide for procedures: used to guide biopsies or drainages with absolute accuracy.
- Medical emergencies: due to its extreme speed, it is the test of choice for evaluating traumas or suspected internal bleeding.
At CreuBlanca, we have state-of-the-art CT scan equipment with dose reduction systems, allowing us to obtain maximum image resolution while emitting the lowest possible radiation for the patient.
Diseases and conditions that a CT scan helps detect
The CT scan is a highly versatile tool that covers multiple clinical specialties:
- Oncological pathologies: allows detecting the presence of tumors, determining their exact size, knowing their location, and checking if they have spread to other organs (staging).
- Cardiovascular and vascular diseases: through a Coronary CT or CT Angiography, obstructions in the arteries, aneurysms, and vascular malformations can be evaluated, or the risk of heart attack can be detected using the Calcium Score.
- Bone injuries and traumas: clearly identifies complex fractures, joint problems, and spinal injuries.
- Pulmonary and chest conditions: key to detecting pneumonia, pulmonary nodules, emphysema, or pulmonary embolisms.
- Abdominal and digestive pathologies: helps diagnose appendicitis, diverticulitis, kidney stones, intestinal obstructions, and conditions in the liver or pancreas.
How long does a CT scan take?
One of the great advantages of this test is its speed. If you are wondering how long a CT scan takes, the actual scanning time is surprisingly short:
- Image acquisition time: the machine takes between 5 and 15 seconds to capture all the information of the area to be examined.
- Total appointment time: including preparation, lying on the table, and receiving instructions from the technical staff, the entire process usually takes between 10 and 15 minutes.
If the administration of intravenous contrast is required to highlight certain vessels or tissues, the total time may be slightly extended by a few minutes for the placement of the IV line.
When should you see a specialist or request your test?
If you have persistent discomfort, or if you suffer from abdominal or chest pain of unknown origin, visit your doctor; if they deem it necessary, it will be time to take the test.
To undergo a CT scan, it is essential to have a medical prescription. If you already have one (issued by public health or a private center), you can expedite your test by requesting an appointment directly at our centers. If you don’t have one yet, our team of specialists can see you in consultation, evaluate your case, and indicate the appropriate test within the same medical group, ensuring continuity of care.
