Peristaltic wave for 5-6 seconds reaches the lower esophageal sphincter, which at this time relaxes, and then immediately contracts, preventing the return of contents into the esophagus (the so-called regurgitation).
The survey radiographs of the skull do not give a complete picture of the state of the temporal bone. In this regard, specialists in the field of radiation diagnosis use mainly sighting images and X-ray computer or magnetic resonance tomograms.
The need for an X-ray of the cervical spine is assessed by the doctor in each specific situation. In most cases, this diagnostic method allows a medical specialist to quickly and accurately determine the diagnosis and begin adequate treatment.
X-ray method allowed to obtain new data on the anatomy and physiology of the musculoskeletal system: to study the structure and function of bones and joints in vivo, in an integral organism, under the influence of a variety of environmental factors on a person.
The most widely used non-invasive diagnostic method for detecting congenital and acquired pathological changes in bone and joint tissues is the visualization of their anatomy with the help of X-rays.
Radiation methods are of considerable help to the clinician in the recognition of adrenal lesions. On the survey radiographs, these glands are not visible. Only in cases where Addison's disease is associated with tuberculosis of the adrenal glands, in the latter, small deposits of lime are sometimes noticeable.
Mammography - radiography of the breast without the use of contrast agents. Radiography is performed on X-ray machines specially designed for this purpose, mammographs. The power of their x-ray tubes is 19-32 kV, they have two focal spots with a diameter of 0.3 and 0.1 mm. The tube anode is made of molybdenum, and the exit window is made of beryllium.
X-ray examination (X-ray radiography) is an X-ray examination method in which an image of an object is obtained on a luminous (fluorescent) screen.
X-ray endovascular occlusion is a transcatheter occlusion of the vessel, its embolization. For this, an embolizing material is injected through the catheter, which temporarily or permanently surrounds the lumen of the vessel. Depending on the caliber of the vessel and the purpose of the procedure, platinum microparticles, microspheres with ferromagnets, hemostatic gelatin sponge, metal spirals, oil emulsions are used.
