Colonoscopy is a modern endoscopic method of diagnosing diseases of the large intestine (from the rectum to the caecum) with an assessment of its condition using a long thin flexible probe – a fibrocolonoscope with a micro-camera at the end. During colonoscopy, the probe is inserted through the anus and progressively moves forward, which makes…
Capsule endoscopy is a modern diagnostic method that allows you to assess the condition of the intestinal mucosa during the passage of a video capsule through the gastrointestinal tract, which the patient swallows. In the process of moving through the gastrointestinal tract, the capsule captures images, and then is excreted from the body naturally. The…
Gastroscopy is a method of instrumental visualization of the mucous membrane of the esophagus and stomach using a flexible fibroesophagogastroscope. Esophagogastroscopy is indicated for dysphagia, signs of bleeding from the upper gastrointestinal tract, suspected polyps, cancer, ulcerative lesions of the stomach or esophagus. Anesthetic aid for gastroscopy is provided by premedication and local anesthesia of…
British scientists from the Institute of Psychiatry, Psychology and Neuroscience have identified a link between prolonged stay at home and severe depression. Specialists observed 164 patients with major depressive disorder. Using geolocation data, they found out how much time the patients spent at home. It turned out that older people with more pronounced symptoms left…
What is dopamine? It is called in different ways: the hormone of joy, happiness, pleasure, and they also say that it is he who controls our passions. Behavior, mood and even the character of a person largely depends on this hormone. He is responsible for attention and motivation, activates the craving for study. What of…
Skeletal scintigraphy allows you to simultaneously determine in which joints inflammatory phenomena caused by rheumatic disease are observed. 2-3 hours before the start of the study, a radiopharmaceutical is injected into the patient’s vein. The drug is distributed throughout the body and accumulates in the places where the greatest number of young bone cells are…
Lymphoscintigraphy is a minimally invasive functional examination of the lymphatic system with the introduction of a radionuclide substance and subsequent fixation of its passage through the lymphatic channel using a special scanning device. It is carried out to determine the features of the structure of lymphatic vessels, the rate of lymph flow, the structure of…
Cholescintigraphy is a radiological method of examining the gallbladder and bile ducts by assessing the accumulation of a radioisotope in the biliary tract. Cholescintigraphy is informative for the detection of acute cholecystitis, disorders of the patency of the choledochus, bile duct atresia, tumor formations, dysfunction of the sphincter of Oddi, failure of postoperative anastomoses, assessment…
Scrotal scintigraphy is a method of functional visualization of the testicles after intravenous administration of isotopes, the radiation of which is recorded by a scintillation chamber. The study allows us to assess the structure of the testicles, their size, shape, position and functional state. It is used in the diagnosis of inflammatory processes, developmental abnormalities,…
Thyroid scintigraphy is a method of radiological examination of the functional activity of thyroid tissue and nodules, based on the assessment of the accumulation of a radioindicator. Scintigraphy allows us to judge the morphology, topography and size of the thyroid gland, to identify its focal and diffuse changes, to identify and differentiate “hot” (hormonally active)…
