MRI of the bladder: which shows, training

 

MRI of the bladder is the most informative instrumental method of the study of this body. It is prescribed to detect anomalies, benign tumors and cancer, calculi, and inflammatory changes. Diseases of the bladder, kidneys and other pelvic organs may have similar symptoms, so before you make a costly MRI, it is recommended to make a few more simple tests. Laboratory analysis of blood and urine, x-ray or ultrasound will help to clarify the localization of the pathological process. Based on these data, the doctor will determine what kind of research feasible.

In some cases, MRI is recommended for examination of the bladder?

MRI – highly informative and completely harmless, but quite expensive method of examination, so it is not used as a screening. Benign tumors or cancer of the bladder, calculi, and inflammatory changes similar symptoms:

Symptoms of bladder lesions are not always specific, so prior to appointment MRI the doctor recommends additional research. In some cases, accurate diagnosis requires CT and MRI.

Indications for MRI consider:

  • Suspicion of the presence of benign tumors or cancer of the body wall is identified based on ultrasound or cystoscopy.
  • Congenital abnormalities of the bladder (watchful waiting).
  • Clarification of the size and nature of the location of the concretion.
  • Planning surgery for bladder cancer and evaluation of its results in the dynamics.

What diseases can be diagnosed by MRI?

Examination prescribed for the diagnosis of diseases and malformations of the body:

  • benign tumors of the wall revealed pathological lesions from 1 mm in diameter;
  • diverticulitis, sclerosis cervical disease (Morion) and other malformations suitable for primary identification and evaluation of the process dynamics;
  • the presence of calculi in the bladder, measure its size and location;
  • hernia of the organ;
  • bladder cancer – MRI with intravenous contrast enhancement to differentiate benign processes, is determined by the size and localization of lesions, provides a conclusion on how involved in the process are located close to structures: peritoneum and female genital organs.

A magnetic field harmless to the body, so it can be done multiple times. This makes MRI the ideal technique for assessing the results of surgical treatment, radiotherapy or chemotherapy of bladder cancer.

When used with contrast enhancement?

If the MRI discovered the tumor, then further carry out intravenous contrast enhancement. This makes it possible to distinguish benign tumor from cancer, to more accurately measure the dimensions and determine the location of the tumor. Malignant tumors have a more developed vascular network, and therefore quicker turn contrast than benign.

Why MRI of the bladder is more expensive than the examination of organs of small pelvis?

The bladder with the help of MRI can be studied precisely or in the composition of the Protocol of inspection of organs of small pelvis. In the first case, the condition of the body is evaluated in more detail: clearly visible, its walls and contents inspected adjacent organs and lymph nodes. Due to the constant fluctuations of the fluid in the bladder to get a clear image difficult, so such a study is considered technically difficult.

During the examination of the pelvic organs, the bladder is examined in less detail, such a study is only useful if based on clinical data it is impossible to assert that the source of the problem is this body, as well as to determine the location of the concretion in the bladder or ureter.

How to prepare for the MRI examination?

Bladder adherent to loops of intestine and can move with the active peristalsis, and it stirs when you receive the image. To study the precise activity of the intestine should be kept to a minimum. To this day it is recommended to avoid food that causes flatulence and increases peristalsis (legumes, prunes, black bread, eggplant, nuts, butter cakes). Preparation also includes purification or mikroklizmy, which is performed before the study.

When conducting sighting MRI of the bladder should be filled. To do this, 2 hours before the start of the study need to stop to urinate, and an hour before the test drink about 1.5 liters of mineral water without gas. If the research is conducted in composition Protocol MRI of the pelvis, fullness of the body should be average. In this case, the quality of training it should be empty 2 hours before the study and not to drink any fluid.

Contraindications and restrictions of the

Contraindications to study a bit, most of them relative. It is necessary to warn the physician about the presence of a pacemaker or a cochlear implant, it is desirable to have at itself the passport of the device or the opinion of the surgeon, implantirovannogo device about the possibility of MRI.

Only some of the implants and the implants can become an obstacle to the MRI. In most cases, a study perhaps, but in the Protocol of its holding, the doctor will make the necessary changes.

Clipping of cerebral vessels is still an absolute contraindication to MRI: a clip in a magnetic field can move. Joint prosthesis and orthopedic plate for osteosynthesis made of titanium, is not magnetized and can not be an obstacle to research.Hip implants can interfere with obtaining an image, so in this case, the question of the advisability of the MRI is solved individually.
