X-ray examination

The best results when x-rays are achieved with the right combination of the two main methods of x - ray examinations fluoroscopy and radiography, using if necessary the contrasting methods of research. Especially valuable results can be obtained when combined in the process prepositional research and radiographic images in purposeful projections, including the patient on side (waterscape and literaria) in the horizontal direction of a beam of x-rays.
The most important advantage radiography before fluoroscopy is that the radiation load on the patient and on the personnel of x-ray offices significantly less.
In the modern requirements antiradiation protection (see) should in all circumstances to limit the application of x-ray radiation in progress x-ray procedures. Especially it is necessary to protect the area of the gonads (sex glands), considering that, besides affecting the skin, radiation affects internal organs, including reduction and absorption of the latter even small doses is most undesirable. It is therefore necessary for all kinds of x-ray examinations to limit field exposure to the optimum dimensions through the use of bellows and diaphragms, and all the rest of the body to be protected from unnecessary radiation, paying special attention to protection of the gonads (especially in children and in patients of childbearing age) with protective lead-impregnated rubber. The use of aluminum filter with a minimum thickness of 1 mm on chest x-ray is mandatory security, because it is filtered (absorbed by the filter) the most couch radiation, which in the absence of a filter would be absorbed by the skin. When working with the radiation of high hardness, it is expedient to increase the thickness of the filter to 2-3 mm Skin focal length, i.e. the distance from the focus x-ray tube to the surface of the skin should not be less than 35 see
When recording, and the reception of patients for x-ray examination to find out did they soon radiological research involving significant radial loads. These imaging studies include multiple images of the skull, the lumbosacral spine and pelvis, tomography these areas, and most of the methods of x-ray examinations with the use of contrast agents, in particular angiography (see), bronhografiya (see), gepatologiia (the study of the liver - gepatopatia and spleen - litografia), barium enema (see), urography (see), cholecystography (see). These and similar x-ray examinations, accompanied by achieving maximum permissible dose (see) radiation, can be repeated not earlier than 6 weeks. Special attention on the part of nurses requires observation and control for the careful preparation of patients to the complex imaging studies with the use of contrast agents. Instructions for preparing patients for x-ray study, developed by doctor-radiologist, you must have at each x-ray room. Their strong performance ensures the success of x-ray and saves patients and staff from unnecessary repeated studies.
The role of nursing and technical staff in the manufacture of the basic methods of radiological research is different. If when scanning task is basically to support normal preset modes of the device and to the observance of necessary measures antiradiation protection and research of the patient wholly performed by doctor, producing an x, when x-ray role of roentgenologist substantially increases and becomes more active and responsible.
