How often can an MRI be performed? People's comments about the procedure

Modern medicine is rapidly developing, and for several years now, as diagnosticians, it has been proposed to conduct a special detailed study of the parts of the body on a special MRI device. A magnetic resonance tomograph allows you to scan any organ. As a rule, such diagnostics are carried out in case of emergency, when other methods of diagnosis are not effective. Doctors on the basis of research confirm or, on the contrary, exclude suspicions about the alleged disease. Sometimes there is a need for reanalysis on this complex device or scanning another organ in a short time. And there is a natural question about how often it is possible to do an MRI, is it dangerous?

How does the device work?

Recently, everyone talks about magnetic storms and their negative impact on human health. Manifestation in the atmosphere of this phenomenon can cause a headache in man. Radiation, which produces a tomograph, is also magnetic. Therefore, people who are assigned to the study are worried - is it harmful to do an MRI in principle?

It is no secret to anybody that this device is one of the most informative ways of diagnosing. And although MRI creates a high-frequency magnetic field, it does not emit X-rays that cause more significant harm to the human body. The tomograph in this respect is safer than the mobile phone that people use every day. Experts, on the question of how often You can do MRI, have the opinion: "Everything that is too - not useful." However, this device does not cause a person any changes during or after the procedure. And if, for some reason, a re-examination is prescribed, you can go through the diagnostics as long as you need without fear.

Necessary precautions

Before carrying out this procedure, the doctor always clarifies the factors that can serve as a contraindication both absolute and relative:

• The first trimester of pregnancy, as possible a negative effect on the fetus.
• Metal objects present in the human body. This can be orthopedic structures, clips on the organs, artificial joints, pacemaker or defibrillator.
• The procedure can be prescribed in an open device if the person has claustrophobia.
• If at the time of diagnosis a person suffers from ENT diseases.
• Severe condition of the patient.
• Tattoos, which include metal elements - earrings, balls.
• Electronic or metal implants.
• Clamps on the vessels of the brain.

The patient himself can not independently appoint a procedure. All these factors are considered by the doctor, and only he can decide how often it is possible to do an MRI and whether to prescribe a re-diagnosis. Perhaps, it is categorically forbidden even once.

In what cases and how many times can an MRI be performed?

There are no limitations for tomography if there are no special contraindications. For example, the diagnosis of multiple sclerosis requires repeated MRI procedures in order to control its spread to the spinal cord and brain. More than once in a short period of time, the study can be performed after surgery or at the stage of preparation for surgery. Often scanning organs is required during the treatment of cancer, chemotherapy, to detect metastases, tumors. After spinal injuries or injuries to the musculoskeletal system, it is also recommended to undergo a second examination.

How is Magnetic Resonance Tomography?

A person changes into a change of clothes, which he can take with him. All things, metal objects must be removed, put out of pockets superfluous.

The patient passes into the apparatus room and is correctly located in the tomograph. During the procedure, a person should lie still. Sometimes it is this condition that causes little discomfort to the patient. But this is not a whim of a doctor, but a necessity. Any, even a small movement can adversely affect the quality of the picture.

The interior of the device is illuminated, the fan is built into the device so that the patient is not stuffy in the enclosed space.

Normal preparation before scanning is not required. Exception - those cases when a contrast agent is used during the examination. Special training is needed in the diagnosis of abdominal and pelvic organs. A few days before the procedure, you should start a carbohydrate diet. Before MRI, do not drink tea and coffee, and 5-6 hours before beginning to stop drinking and eating. You should drink a tablet of activated charcoal if there is flatulence, and take the medicine to relieve the spasm.

Opinions on the MRI procedure, reviews of people

As a rule, many of us are afraid of something new and unknown to ourselves. Some people who have been assigned tomography, for the first time with caution, go to the examination. But the result is that in this procedure there is nothing terrible. So, what do people say about MRI? The responses of patients who underwent this procedure are reduced to one thing - there is nothing terrible and dangerous in it. Especially since here it is a question of the state of your health. The only nuance that can be an obstacle to the research is the question of how often it is possible to do an MRI. After all, if a person needs repeated repetitions of procedures, then it's worth knowing for sure.
