What is prohibited in MRI?

Magnetic resonance imaging (MRI) is a noninvasive method for visualizing internal body structures and may detect problems such as cancer, heart disease, or muscular dystrophy. MRI uses a large magnet, radiofrequency signals, and a computer to produce detailed images of organs and tissues without using radiation. The images can be manipulated and combined to form three-dimensional pictures of the area being studied. MRI is an important diagnostic tool for many diseases and can be used in conjunction with other types of medical tests and procedures.

The MRI scanner can be uncomfortable for some patients. It can be noisy, and some people experience claustrophobia, especially if the scanner RMN Bucuresti is open. Medications can be given to help the patient tolerate the test. Most MRI exams are painless. After the exam, the patient will receive a set of visual images from the scanner on a computer and hard copy films. The radiologist will interpret the scans and send them to the patient’s doctor for review. The results of an MRI scan usually take 1 to 2 days to complete.

In a MRI scanner, the patient lies down on a table that slides into a tunnel-like tube. A technologist will be able to see and hear the patient throughout the procedure through a two-way intercom. The technologist will give the patient earplugs or headphones to decrease the noise from the scanning machine. Music can be played through the earplugs to make the exam more bearable. Patients with metal objects such as hearing aids, watches, or jewelry should leave them at home. These items can be attracted by the strong magnetic field of the MRI system and could be damaged. Patients should also avoid bringing personal electronic devices such as cell phones or PDAs into the scanner room.

MRI is widely used in a variety of medical fields because it is safe and provides detailed images of various parts of the body. It is an excellent tool for diagnosing many conditions, including tumors, stroke, and other disorders of the brain, liver, and kidneys. It is also an excellent tool for examining soft tissue injuries and infections. MRI is a noninvasive technique that does not use ionizing radiation, making it suitable for children and pregnant women. It is also the preferred imaging technique for most musculoskeletal conditions of the joints and extremities. Patients with metal implants should notify the MRI staff, as they might need to be removed before the procedure. A special type of MRI called an open scanner is available for patients with claustrophobia, allowing them to be tested safely and effectively. MRI is also useful in the diagnosis of some neurological conditions, such as dementia and epilepsy. In addition, MRI can be used to visualize small abnormalities in the brain and spinal cord, as well as for monitoring changes in blood flow and metabolism. MRI can also be used to inject contrast agents to highlight certain areas for further investigation. In some cases, the radiologist can use these images to plan treatment or surgery.
