MRI is a diagnostic test that uses a magnetic field and radiofrequency waves to obtain images of different areas of the body.
High-quality images can be obtained and changes in your body can be seen without using ionizing radiation (X-rays).
MRI helps doctors find cancer in the body and identify signs that the disease has spread. It can also be observed if there is inflammation or infection in the brain, nerves or joints. You can diagnose musculoskeletal injuries such as tendinitis, ligament injuries, cysts, or herniated discs. It can also help plan cancer treatment, with surgery or radiation.
Magnetic resonance is one of the most reliable diagnostic tests, in addition to serving as a complement to the usual techniques (mammography and ultrasound). The MRI examination is painless and more importantly, electromagnetic fields do not cause any known damage to tissues. MRI is safe and painless.
Through magnetic resonance imaging, the doctor examines the organs, tissues, and skeletal system. It produces high-resolution images of the inside of the body that help diagnose various problems.
The difference between CT is indicated to essentially see bones and lungs, while Magnetic Resonance allows visualizing soft areas of the body. A CT scan takes about half an hour and an MRI usually takes more than an hour.
