Magnetic resonance imaging is a modern method for studying the structure, condition, and function of internal organs. It is based on the measurement of electromagnetic waves emanating from body tissues. These signals are transmitted to a computer, which decodes them and converts them into an image. The obtained data is analyzed and evaluated by a specialist conducting an MRI.
Modern equipment allows obtaining a three-dimensional image of the internal organs so that the study has high information content. MRI helps to identify a large number of diseases that are not so accurately diagnosed using other methods.
MRI has great advantages over invasive and radiographic methods, as it is a safe and comfortable procedure. Due to this, the study is used in the diagnosis of diseases of many organs and systems:
- Vessels of the neck and brain;
- Jaw and temporomandibular joint;
- Spinal cord;
- Abdominal organs;
- Pelvic organs;
- Respiratory system;
- Endocrine system;
- Lymphatic system;
- Reproductive system.
One of the most common areas of magnetic resonance imaging in the diagnosis of diseases of the nervous system. MRI of the brain allows detecting tumors and determining the stage of their development, diagnosing problems with vessels, multiple sclerosis, and other pathologies.
Many patients are interested in - with MRI of the brain, radiation occurs, and is it dangerous? What dose of radiation does the body receive during the research? Is MRI Hazardous to Health?
MRI Radiation Level
Unlike X-rays and computed tomography (CT), patients receive a zero dose of radiation during an MRI scan, since this study is not based on ionizing radiation, but on electromagnetic effects.
The effect of a magnetic resonance imager is comparable to that of a cell phone or microwave. MRI done by MRI test labs in Delhi does not cause irregularities in the structure, condition, and function of tissues and organs, being at the same time a highly accurate diagnostic method.
Therefore, you can be sure that there is no radiation during an MRI scan of the brain.
Magnetic resonance imaging in oncopathology?
Patients with oncologic MRI are prescribed with the use of a contrast agent - to increase the information content of the study: this allows a detailed study of the tumor and its vascular network. Due to the high precision and diagnosis, the most effective treatment is prescribed.
The absence of irradiation provides the possibility of using MRI for cancer patients with confirmed diagnoses of various malignant tumors, which are not recommended for X-ray methods. X-ray and computed tomography due to ionizing radiation harm the tissues of the body: cause changes in DNA and adversely affect the already existing pathological processes. Electromagnetic effects during MRI are safe for both tumors and healthy tissues and organs.
How often can I do magnetic resonance imaging?
In the absence of contraindications, MRI may be prescribed - depending on the disease and the characteristics of its course - as often as necessary to develop an effective treatment plan or to correct it. Since the procedure is safe for the body, it can be carried out with a minimum time interval.
The frequency of an MRI can only be determined by a doctor. If there is an urgent need or in accordance with the developed plan of dynamic observation, the study is carried out several times in one day.
