TAC or CT scan
It is known as computerized axial tomography or CT, it is a diagnostic test that uses x-rays to obtain radiographic images of the inside of the body in the form of cross-sections or in the form of three-dimensional images. It is used in the event of trauma to detect bleeding, injuries to internal organs and fractures, to diagnose tumors, to evaluate pathologies of the spinal cord or spine, to guide interventions such as biopsy and drainage of abscesses, and to diagnose some infections.
Sometimes a liquid known as the contrast is administered, this iodine compound enhances the images obtained by the CT scan to facilitate the interpretation of the results.
It is a test that uses a computer that obtains an image of the soft tissues of a patient using a magnetic field. Very powerful radio waves and images are used to create images of the body. It is a test used to obtain clear images of the soft tissues that surround the bones, which is why it is used for diagnosing spinal and joint problems, for sports injuries, especially those that affect the shoulder, knees, hip, elbow, and wrist. The images allow us to observe tears and injuries in ligaments and muscles. It is also used to view the heart, aorta, blood vessels, and coronary arteries. It allows examining organs such as the lungs, liver, kidneys, pancreas, and vessels.
Differences between CT scan and MRI
- CT uses X-rays.
- MRI uses a magnetic field.
- CT can be done quickly.
- An MRI takes more time to perform.
