MRI in urology in Moscow

Do you have lower back pain, high blood pressure for no apparent reason, and problems with urination? We recommend that you undergo a comprehensive examination - MRI of the prostate and kidneys. In Moscow, diagnostics are carried out at the K + 31 multidisciplinary medical center.

Magnetic resonance imaging (MRI) in urology is a non-invasive and safe technique that allows you to visualize the internal structures of the body in great detail.

What is an MRI of the genitourinary system?

The unique method is based on the resonance (response) of hydrogen proton nuclei to electromagnetic waves in a powerful magnetic field. Its advantage over other methods of radiation diagnostics is the absence of ionizing radiation.

Please note: The human body is more than 80% water, the molecule of which includes 2 hydrogen atoms.

The MR scanner is essentially a large magnet. It takes approximately 20-25 minutes to obtain an image of a specific area of the body. Supply ventilation is provided in the capsules of the devices, the so-called. an alarm button and a communication system with a diagnostician.

MRI is prescribed as part of a comprehensive examination, to make a preliminary diagnosis, monitor the effectiveness of therapy, and in preparation for surgery.

The technique helps to detect:

  • stones (stones) of the kidneys and urinary tract;
  • cystic and neoplastic neoplasms of the urogenital system;
  • anomalies in the development of the pelvic and abdominal organs;
  • deformation of the kidney or its omission (nephroptosis);
  • Adenoma and prostate cancer in the early stages of development.

Important: With the help of tomography, some pathologies are diagnosed that cannot be detected during X-ray, ultrasound and CT of the prostate. It is indispensable in the diagnosis of prostate cancer, as it allows you to detect even the smallest changes in tissue structures.

What does an MRI of the prostate with contrast show?

MRI of the prostate with contrast helps to diagnose not only oncology, but also inflammatory processes in the tissues.

The urologist refers the patient for a CT scan if there are complaints of dysuria (frequent urges), urinary incontinence at night, difficulty urinating, blood (or mucus) in the urine, and a feeling of incomplete emptying of the bladder after visiting the restroom. These symptoms can be combined with general weakness and fatigue.

The procedure has a number of contraindications.

These include:

  • taking β-blockers and interleukins;
  • severe anemia (anemia);
  • bronchial asthma;
  • epilepsy;
  • clinically significant kidney dysfunction;
  • blood diseases (particularly myeloma);
  • claustrophobia (fear of closed spaces);
  • individual hypersensitivity to a contrast agent;
  • Installed pacemaker

If an MRI of the prostate with contrast is due, the doctor should be warned about the presence of fixed dentures (crowns and bridges) made of metal, orthodontic appliances (for example, braces), as well as metal pins and plates in the body.

Metal alloy structures tend to heat up and move in a strong magnetic field, which can cause mechanical injury and thermal tissue burns.

Please note: The paramagnetic contrast agent given intravenously before the procedure does not contain iodine. Therefore, complications do not occur even in people with a burdened allergic history.

Here's what an MRI of the prostate shows in men:

  1. adenomas (benign tumors);
  2. growth of tissue (hyperplasia);
  3. genetically determined anomalies;
  4. limited purulent inflammations (abscesses);
  5. prostatitis (acute or chronic inflammation of the gland).

With MRI of the prostate gland with contrast, the doctor determines the localization of the neoplasm and additionally assesses the condition of the seminal vesicles, testicles, vas deferens, urethral canal, bladder, fiber and muscles of the lumbar region and small pelvis.

On MRI, the anatomy of the prostate and surrounding tissues, as well as the location of the great vessels, are visible in great detail. When diagnosing cancer, it is possible to determine whether the tumor process has affected the regional lymph nodes.

What does an MRI of the kidneys and urinary tract show?

Three-dimensional imaging is required for injuries of the abdominal and inguinal region, pain syndrome of unclear etiology, suspected urolithiasis (urolithiasis), obstruction and stricture (cicatricial changes) of the ureters.

The study on a tomograph is also carried out with central and peripheral edema, renal colic, the likelihood of kidney metastases, congenital anomalies of the urinary system and contraindications to radiography.

Important: MRI of the kidneys is necessary if the patient complains of arterial hypertension (high blood pressure), which does not help conventional antihypertensive drugs.

Magnetic nuclear resonance allows you to recognize:

  • anomalies in the development of the excretory system;
  • kidney prolapse;
  • traumatic injury;
  • large and small stones (stones and sand);
  • benign neoplasms (papillomas, hemangiomas, myomas, fibromas, lipomas);
  • cancer tumors;
  • cysts;
  • abscesses;
  • hydronephrotic transformation (edema of the kidney);
  • inflammatory process (glomerulonephritis, pyelonephritis).

Analysis of MRI data of the kidneys and urinary tract helps the urologist to draw up an individual program of conservative treatment and determine the need for surgical intervention.

Preparation for the study (MRI) of the prostate, kidneys and urinary system

When preparing for an MRI scan of the kidneys, prostate and ureters, it is recommended to refuse products that increase gas formation in the intestines on the eve of the procedure. These include rye bread, muffins, fruit juices, raw vegetables (especially cabbage), legumes (beans, peas, lentils), and sugary sodas.

Important: Be sure to remove all metal jewelry before the procedure.

Meal (light breakfast) is allowed no later than 3 hours before tomography (if intravenous contrast is supposed to be injected). An hour before the procedure, it is recommended to drink 500-700 ml of water without gas and not to empty the bladder (it requires an average filling).

For 6-8 hours, it is recommended to take an antispasmodic (Drotaverine, No-shpa) and a carminative (for example, Espumizan). It is advisable for the patient to take with him the data of previous examinations (including CT, ultrasound and x-rays).

Please note: Tomography is not performed if the subject's weight is >130 kg or waist circumference ≥150 cm. The diagnostic procedure is not prescribed for children under 5 years of age, as it is difficult for them to remain still for 20 minutes or more.

In case of hyperactivity, fear of closed spaces and increased anxiety, patients are advised to take a sedative or anxiolytic (tranquilizer) in advance. Diagnostics on a tomograph cannot be carried out if a person is under the influence of alcohol or other psychoactive substances.

At the slightest suspicion of a pathology of the genitourinary system, make an appointment with the urologist of the K + 31 medical center. We have state of the art equipment.

MRI examinations are carried out by doctors of the first and highest category. They regularly improve their skills at courses and seminars, and work in strict accordance with the protocols and world standards for diagnosing diseases. Their professionalism is evidenced by the reviews of patients left on the site, whom the specialists of the medical center helped to maintain their health.

We guarantee our wards complete anonymity. Personal data and information about the manipulations performed will never get to outsiders.

In our clinic, the prices for hardware examination methods are quite affordable. There is a loyalty program for regular customers and a flexible system of discounts. Appointments are made by phone and online.
