Why is contrast needed in a CT scan?
Computed tomography with contrast is an examination with a very high diagnostic value, because the contrast agents absorbs the radiation emitted during the examination differently than the surrounding tissues, which makes them more visible.
Is the radiation dose in a CT scan safe for the patient?
There is practically no safe dose of radiation, and the amount of radiation dose taken depends on the type of CT examination. However, a single examination does not pose a threat to health and life.
Will I receive the CT scan results right away?
Scan results are usually not available right after the examination is completed. The computer processes the information from the images taken, which are then interpreted by the radiologist.
How many CT scans can be done in a year?
There is no recommended limit for the number of examinations, but they are not indifferent to a living organism. Therefore, these examinations can only be performed on the basis of a doctor’s referral – even if it is a private examination. Used too often or in too high doses can adversely affect the body. In the case of children or seniors, a CT scan is recommended only when the diagnostic benefits are greater than the potential risks. This examination is not recommended in pregnant women. The doctor refers the patient when it is necessary to make a diagnosis and based on clinical indications.
What is the difference between a CT scan and an MRI scan?
Both magnetic resonance imaging and computed tomography are diagnostic imaging examinations. They enable obtaining accurate images of tissues and organs in various planes, also in 3D technology. In both examinations, the patient is placed on a table, which is then slid into the scanner. Remain still during both examinations. Both examinations are painless and non-invasive. The difference is in the imaging method. During MRI, a magnetic field is used. In the case of computed tomography, X-rays are used for imaging.
