Magnetic Resonance Tomography (MRI, MRT, MRI) is a tomographic method to study internal organs and tissues using the physical phenomenon of nuclear magnetic resonance – the method is based on measuring the electromagnetic response of the nuclei of hydrogen atoms to excitation by a certain combination of electromagnetic waves in a constant magnetic field of high voltage.
How do MRIs work?
Magnetic resonance imaging (MRI) uses a magnetic field to capture organs and tissues in the human body. MRI is a modern technology that does not use X-rays to scan the human body.
How is MRI performed? How does MRI work, the principle of operation? The magnetic field of the MRI device during the examination works on water molecules in the human body, and radio waves form signals from these molecules and give an opportunity to see the image of internal organs and tissues of the body. The advantages of MRI over others are greater than the disadvantages.
Magnetic resonance imaging is a popular diagnostic method because magnetic fields and radio waves are absolutely harmless to human health, unlike X-rays.
Information about the state of the musculoskeletal system, internal organs and nervous system, which gives us MRI Calgary allows the doctor to diagnose the disease even at an early stage and prescribe the most effective treatment. By the way, the prices for MRI in our diagnostic center will pleasantly surprise you.
What is MRI used for?
MRT for examination of brain and spinal cord.
Namely, MRI diagnostics makes it possible to detect such pathologies:
- Development pathology
- Pituitary gland disease
- Multiple Sclerosis
- Progressive dementia
- Spinal cord injury
MRI bone and joint diagnostics
Magnetic resonance imaging is the main examination technology for such diseases:
- Intervertebral disc herniation.
- Spinal canal stenosis
- Joint injury
- Bone infection
MRI scan of internal organs
Identifies pathologies and tumors in these organs:
- Lungs .
- Breast Diagnostics with Mrt
- To detect breast cancer, in addition to mammography, MRI is also used.
- MRI treatment
No special preparation for the examination is required. MRI examination lasts from 10 to 40 minutes. The patient must be dressed in natural fabrics underwear, leave all metal objects (jewelry, piercing, dental prosthesis, etc.), cell phones, hearing aid, keys in the changing room. The result is given out immediately after the examination.
Preparation for MRI
You can take medication, eat and drink as usual before preparing for MRI diagnostics in Kiev, if you do MRI without contrast. Tell your doctor if you are claustrophobic, or if you are afraid that being in an enclosed space can bring you discomfort, as well as scare. You will also be given special disposable clothing before your examination.
Examination MRI procedure
You will be on a movable table, which will move inside the device until the necessary part of the body is in the center of the magnet. You may be asked to wear a special head fixation device if you need a brain test. Most of your body will be outside the CT scanner, as modern MRI machines are wide and short. In order for the image to be clear during the examination, you need to breathe calmly, without moving your head and body. There is no need to be afraid of the noise made by the CT scanner. If necessary, a friend or family member can be with you. If you are uncomfortable or need help, please let the staff know before you start the examination.
You may be asked to insert a special MRI contrast into your vein, which helps to obtain additional information and improve image quality. It is recommended not to drink or eat 2 hours before this examination.
After the diagnosis, you will be asked to wait until the pictures are reviewed and the doctors are sure that you do not have to take additional pictures.
