What does mr and ct exam mean

MR examination is a method of non-invasive examination of the inside of the human body using magnetic **** vibration technology. This examination method is characterized by clear imaging, no radiation, and no harm to the body, and is therefore widely used in the examination of diseases of the brain, bones, heart, lungs and other parts of the body. mr examination requires the patient to be stationary in a magnetic field and to maintain coordinated breathing during the examination in order to ensure the accuracy of the imaging effect.

CT examination refers to computed tomography, a technique that uses X-ray imaging to reconstruct the layers of images produced by the human body into a three-dimensional image in order to show localized lesions and abnormal structures.CT examination has advantages over other imaging techniques in terms of examination speed, resolution and the ability to observe fine structures, and it is widely used in the diagnosis and treatment of difficult cases. For example, lung nodules, liver cancer and abdominal cavity diseases.

MR and CT are two common medical imaging techniques that produce images in different ways to localize lesions and help diagnose and treat diseases. Often, doctors will decide which imaging technique is more appropriate based on a patient's symptoms and medical history. It is important to note, however, that both tests are medical devices that require specialized personnel to operate, and patients need to follow their doctor's instructions to the letter to ensure the quality and safety of the test.
