Magnetic resonance imaging (MRI) of the kidneys is a universal method for examining internal organs using radiofrequency pulses. Diagnosis is suitable for people who have contraindications to CT. If a person has adverse symptoms in the form of lower back pain, swelling and severe chills, it is better to consult a doctor. Unreasonable factors for undergoing research are discomfort in the kidney area, fever and severe chills.
Why is an MRI done?
To detect or exclude malignant neoplasms in the adrenal glands and kidneys, magnetic resonance imaging is performed. By means of high-tech equipment, local affected areas are determined.
The equipment allows:
- track inflammatory changes in tissues;
- mechanical damage due to impact or injury;
- stages of the disease, tumor parameters (size, shape, etc.);
- get pictures in projections and cuts of the kidneys, ureters;
- conduct examinations without surgical intervention and ionizing radiation.
Using magnetic fields and radio frequency pulses helps to detect even the smallest changes in the structure of biological human tissue. Timely diagnosis of the body helps to quickly respond to diseases. A correct and prompt diagnosis reduces the effort and cost of treatment. There are many examples when MRI literally “saved” a person’s life. Patients often go to the hospital if the disease has already become chronic. This speaks of a neglected state of health. In this case, every minute and hour counts. Precious time should not be wasted when it comes to human life.
If the patient was given a referral to undergo a magnetic resonance procedure, then it is advisable not to hesitate with this. After all, the dynamics of the treatment of the disease and pathological kidney changes.
What you need to know before going to the office to the diagnostician?
For patients who are to be diagnosed using the magnetic resonance method, there are a number of rules. The patient must have a passport, sheets and clothes with him. free cut, not containing metal inserts. Also follows:
- get rid of metal objects;
- no need to drink large amounts of liquid;
- remove mobile phones and bank cards;
- undress to underwear (made of natural fabric);
- no need to be afraid of extraneous noise in the form of clicks.
The person is given headphones or earplugs that allow them to feel comfortable during the procedure. If you have any questions, you can contact the doctor through the intercom. During the diagnosis, it is forbidden to move. Any movement during an MRI will affect the accuracy of the image.
Who should be contacted?
Modern clinics, which are equipped with excellent equipment, can perform standard procedures, as well as events with a pronounced individual approach. For a clarifying diagnosis, magnetic resonance imaging is done with the introduction of a contrast agent. This is necessary for an improved study of organs and a general picture of what is happening.
Transparent marker as a contrast agent visually different from each other various fabrics and structures, which improves image quality. It is relevant when cheaper methods (CT, ultrasound) do not give clear results.
Before going to a diagnostician to examine the kidneys on a tomograph, it is advisable to contact other specialists who are experts in the relevant field. Depending on the specifics of the symptoms of the disease, the therapist, urologist or nephrologist will issue a referral.
A preliminary visit to the doctor will avoid many misunderstandings in the course of diagnosing the disease.
Carrying out magnetic resonance imaging of the kidneys
Obtaining detailed results and analysis in MRI is safe and non-invasive for health. The patient lies on the couch and is placed in a special capsule, which is absolutely harmless to health. By means of pulses of a radio frequency nature, energy is radiated in an electromagnetic field. The receiving equipment transmits the reflected signals to a computer, which processes them and converts them into an image.
Received image analyzed by a radiologist, and he decrypts the received data, which allows you to establish a correct and unmistakable diagnosis.
Thanks to nuclear magnetic resonance, you can learn almost everything about the kidneys and tissue structure (contrast method). MRI indicators are recorded in a special block with subsequent data collection. They allow you to describe the physiological processes in living tissues as clearly as possible.
Radiation diagnostics functions due to the interaction of radio waves and a magnetic field. The device with a sliding table is similar to an elongated capsule. The couch can move relative to the tomographic magnet.
Images in XNUMXD space
Thanks to 3D computer technologies, it is possible to obtain three-dimensional images of body organs, taking into account the visualization of sections of the tissue structure. Such a picture is like a map of the disease, which helps to draw practical conclusions and take appropriate actions to eliminate the disease.
A clear picture captures the smallest details and clearly demonstrates oncological neoplasms, inflammatory processes. Thanks to the resulting images, you can observe the trend and effectiveness of the treatment of the problem organ. This is especially true for long-term events.
Why use MRI diagnostics?
The positive aspects of the use of magnetic resonance therapy are the absence of pain and destructive factors (violation of the integrity of organs). The advantages of MRI include the absence of radioactive radiation, no special preparation is required (diet, etc.). Subject to the recommendations of the doctor, the images are obtained in high resolution and quality without distortion.
This method is considered one of the most reliable and informative sources for making the correct diagnosis. It allows you to get a general idea of the lesions of organs, pathological abnormalities.
Limitations to magnetic resonance imaging
MRI is not recommended for expectant mothers in the 1st trimester of pregnancy in order to protect the child from any radiation. Patients with decompensated heart failure and fear of closed spaces should also refrain from such procedures. People with metal implants and fragments, pacemakers should not be allowed to perform such diagnostics.
Relative contraindications for MR imaging include renal and hepatic decompensation, allergic reactions to a contrast agent.
It should be remembered that you should not run for an examination without first communicating with your doctor. After all, a specialist can determine the degree of relevance of such events, its features and compatibility with other alternative options (laboratory tests, CT, ultrasound).
