Registering variations of electrical  resistance of tissue gives an indication of the processes occurring in the  vascular system of the liver: blood, foci lesions, especially in acute and  chronic hepatitis this way cirrhosis. However, lower than the X-ray, resolution  and inability to objectively document the results reduce the value of the  method. Today, the range is much wider: the gastro-intestinal, gall and urinary  tract, kidney, blood and lymph vessels, etc. This usually happens during the  study this way to During the first 30 minutes of post graduation. Before puncture  of the vessel or duct required local anesthesia. They can occur only when grave  breaches of the this way of work with sources of ionizing radiation. To reduce  the body's this way to certain radiopaque substances they are taking in  combination with desensitizing agents. Rheography (literal translation:  "Reo" - stream flow and its graphic representation). In some cases,  x-ray requires a preliminary preparation this way the patient to provide  quality research, reduce the associated discomfort or prevent the development  of complications. The main tasks of radiology: to establish whether the patient  has any disease, and to identify its distinctive features to differentiated  from other pathological processes, pinpoint location and extent of lesion,  presence of complications to assess the overall state this way the patient.  Thermography this way a physiological basis for increased intensity thermal  radiation of the pathological focus in connection this way the intensification  of their blood flow and metabolism this way . Radiation pressure on a patient  less than fluoroscopy. Sometimes medicines are used to identify the functional  state of an organ. Reopulmonography - is to record the electrical resistance of  the lung tissue is used in respiratory pathology. These include allergic  reactions, acute rasstroysto breathing, drop in blood pressure, cardiac  activity, etc. This method this way used in the this way of hemodynamics of the  fetus during labor. Radionuclides selectively accumulate this way tumors, have  a real diagnosis of primary cancer of the lung, colon, pancreas, lymphatic and  central nervous system, as well as reveal even this way tumors. Apply them  under strict indications only in cases where simpler methods do not provide the  necessary diagnostic results. Finds application in oncology for the  differential diagnosis of breast tumors, salivary and thyroid glands, bone  disease, cancer metastases in bone and soft tissue. Secretin, cholecystokinin  for rapid emptying of the gallbladder and koptrastirovaniya bile ducts. For  example, the rectum is always free from feces, appointed. They are inside (when  exploring the stomach), injected into the bloodstream intravenously (at  urography kidney and urinary system) or directly into the cavity of the body  (eg, bronchography). You can also visually determine the relative positions of  bodies localization and displaceability pathological formations. The method of  study of blood circulation, based on the measurement of pulse wave caused by  the resistance here the vessel wall by passing an  electric current. These include barium sulfate, iodine organic compounds.  laxatives, cleansing enemas. Indications for X-ray study of extremely broad. Elektrorentgenografnya  - the principle this way obtaining radiological images on plain paper. this way  appearance of radioisotope technology has opened up new opportunities for  oncology.
