Computed Tomography Scan (CT)
A CT scan is an imaging diagnostic technique that uses ionizing radiation for studies that need a high level of detail
Its special characteristics allow obtaining a complete image of any part of the body in just a few seconds, which enables through multislice helical technology to perform reconstructions in three dimensions of bone structures and the vascular system, all with a high diagnostic value.
Our CT Siemens Somaton Definition AS + 128 cuts allows the completion of any study, reducing the time and dose of radiation in a very considerable way, providing the highest image quality. Its latest software updates were carried out in 2018, and the spatial resolution of the image has been improved, with a dose reduction up to 60%.

Tests
Simple CT in any location/body part
With contrast and without contrast
Musculoskeletal CT
With contrast and without contrast
Brain study
With contrast and without contrast
Angio CT
This test allows the assessment of the patient’s vascular system. For the diagnosis we use 3D reconstructions of the arterial system. For this test, the patient is administered iodinated contrast intravenously, and therefore the patient should perform the test with 6 hours of fasting.
Coronary angiography and calcium score
A multi-slice CT coronary angiography is a very useful technique for the diagnosis of cardiac pathology on daily clinical practice. The patient is subject to electrocardiographic monitoring before and during the test. First, a calcium score is performed in order to quantify the presence of calcium in the coronary arteries. Although this test can be performed independently, the diagnosis can be limited if it is not paired with a coronary angiography. The patient is injected intravenously with an iodinated contrast. The patient must provide their medical history before the test is carried out, so that our specialists give the correct preparation guideline, which is customized for each patient.
Virtual colonoscopy
This fast and non-invasive test has led to a great advance in the diagnosis of colon pathologies. The test consists of air insufflation in the colon and the subsequent capture of images that will then allow the doctor to perform a 3D reconstruction of the interior of the colon. Then, the doctor can proceed to its study using navigation techniques. The performance of this test requires an exhaustive preparation for intestinal cleansing. The patient will be guided through the procedure when taking the appointment.
CT scan of the abdomen and pelvis with oral and intravenous contrast
The patient must have had 6 hours of fasting.
Chest CT
With contrast and without contrast
Urography
With contrast and without contrast
Safeguards for contrast tests
It is recommended to all patients that after performing the test with contrast, they should drink plenty of water to facilitate the elimination of the contrast through the kidneys.
Patients with renal failure
For tests with contrast, it is advisable to provide us with a recent analysis in order to assess the renal function. There are cases in which the administration of contrast is not recommended outside the hospital or it could require the application of a renal protection protocol.
Patients allergic to iodine
Iodine is used as a contrast medium during the CT scan. This can cause allergic reactions of varying degrees in the patient. Before taking the test, you will be duly informed about the administration of the contrast. Moreover, the patient must notify our healthcare staff of any previous episode of reaction to the contrast.
Diabetic patients
Diabetic patients who need to go under a CT scan with contrast and take METFORMIN, should stop their treatment two days before and two days after the test. Insulin, however, is compatible with the administration of contrast, so the treatment should not be discontinued.
Frequent questions
Can I have a CT scan without a prescription?
At Marti-Torres Clinic we always recommend the patients to visit their specialist doctor, who is in charge of prescribing the test. There are many types of tests that can be done in order to diagnose or foreclose a pathology. The CT scan, by using ionizing radiation, should be used in the context of a clinical follow-up that justifies its application, since in many cases less invasive tests are sufficient to make a good diagnosis. In addition to guiding you on the type of test to be performed, your doctor will recommend the administration of contrast or not.
What adverse effects does the radiation used in the CT scan have?
Nowadays, the risk of exposure to ionizing radiation is minimal. In our center we have exhaustive control mechanisms to ensure that the dose of radiation emitted in each test is the minimum necessary in order to obtain a quality image for diagnosis. However, it should be remembered that it is not advisable to undergo X-ray tests if they are not justified in the context of a clinical follow-up.
Can I drink water during the fasting?
Yes. During fasting you can drink some water to hydrate yourself.
What effects can the contrast have?
If you are not allergic and you are injected with iodinated contrast to perform a CT scan, you may feel a sensation of heat in the area of the arm where you have been punctured. Then you will not feel anything and you can continue doing your normal life. It is convenient that you drink plenty of water throughout the day after the test to help with eliminating the contrast. However, we will inform you rightfully about the administration of the contrast before performing the test.
