Ventriculoscintigraphy

Ventriculoscintigraphy (ventriculo- + scintigraphy synonym radioisotope ventriculography) is a radionuclide method for studying cerebral hemodynamics, based on recording the distribution in the ventricular system of the brain of a radiopharmaceutical injected into the cerebrospinal fluid.

Allows you to evaluate the speed of liquor flow and identify disturbances in liquor dynamics. It is used for the diagnosis of hydrocephalus, arachnoiditis, brain tumors and other diseases accompanied by changes in liquor circulation.

Ventriculoscintigraphy (radioisotope ventriculography, synonym radioisotope ventriculoscopy) is a radionuclide diagnostic method used to assess the condition of the ventricles of the brain. It is based on the introduction of radioactive isotopes into the patient's body and subsequent scanning of tissues using a gamma camera.

Ventriculoscintigraphy allows you to assess the condition of the walls of the ventricles, their shape and size, as well as identify the presence of anomalies and tumors. This study can be useful in diagnosing various brain diseases, such as hydrocephalus, tumors, ischemic injuries and others.

To perform ventriculoscintigraphy, various radioactive isotopes are used, such as technetium-99m, sodium pertechnetate, gallium-67 chloride, etc. These isotopes are introduced into the body through veins or as an injection into the ventricles of the brain. Then the tissue is scanned using a gamma camera, which records the distribution of the isotope in the tissue.

The results of ventriculoscintigraphy can be used to determine the stage of the disease, select treatment tactics and evaluate its effectiveness. In addition, this method may be useful for monitoring the condition of patients after neurosurgical operations.

Although ventriculoscintigraphy is a safe diagnostic method, it may have some risks associated with the administration of radioactive isotopes. Therefore, before conducting the study, it is necessary to carry out appropriate preparation and ensure that there are no contraindications.
