Fluorescein angiography is an objective diagnostic method in ophthalmology that allows you to register the circulation of fluorescein in the vessels of the inner shell of the eye. The technique makes it possible to identify functional and organic changes, to determine the structure and localization of focal lesions of the retina. It is used to study…
Renal angiography is an X-ray examination of the renal arteries by administration of a radiopaque substance. It is used for the diagnosis of accessory vessels, tumors of the kidneys and retroperitoneal space, narrowing and blockages of the renal arteries; with hydronephrosis and renal hypertension. During renal angiography, a catheter is inserted through the femoral artery into…
Pulmonary angiography is a technique of invasive contrast radiography of pulmonary circulation vessels. There are selective (selective contrasting of individual branches of the pulmonary artery) and general (contrasting of the entire small circle) angiopulmonography. Lung angiography is indicated for detecting anomalies of pulmonary vessels, PE, etc. vascular pathology. Under local anesthesia, after puncture of the right…
Cerebral angiography is a method of examination consisting in an X-ray examination of the cerebral vascular network after the introduction of a contrast agent into the bloodstream. Contrasting makes it possible to study the features of the structure of blood vessels, to identify pathological abnormalities in the blood supply to brain tissues. Angiography is prescribed for…
Aortography is an X-ray examination of the thoracic or abdominal aorta and its vascular branches after preliminary catheterization and filling with contrast. It is indicated for suspected aortic valve insufficiency, aneurysm, atherosclerosis, occlusion of the aorta and its main branches, for the diagnosis of a number of pathologies of the abdominal and thoracic cavity. Aortography is…
The fundamental factor for determining the adequate treatment of any disease or condition is an accurate understanding of the causes and mechanisms of their development. Understanding what causes itching in the patient, specialists can choose the most appropriate way to eliminate it. However, as the recent discovery of American scientists has shown, the mechanism of…
Liver elastography (fibroscanning, fibroscan, elastometry) is a method of ultrasound assessment of tissue elasticity using a standard ultrasound machine equipped with a special sensor. It allows you to visualize the liver, determine its size, position and shape, the structure and integrity of the capsule, as well as the structure of the parenchyma in the entire…
Breast elastography is a method of ultrasound evaluation of the elasticity of the glands based on the results of low pressure and obtaining a color image showing areas of different densities. Allows you to evaluate the structure of the mammary glands and regional lymph nodes. It is used in the diagnosis of pathological formations of various…
Uterus elastography is a method of ultrasound imaging of the uterus with determination of the degree of elasticity of its various sections using special sensors. Allows you to evaluate the layered structure of the uterus and appendages, provides information about the cervix, the lumen of the uterus and the structure of the endometrium, the width of…
Lymph node elastography is a method of ultrasound assessment of tissue density using special equipment in addition to conventional ultrasound sensors. Allows you to assess the degree of stiffness of the lymph node in different areas, compare the data obtained with the available indicators of the norm and specific pathologies. It is used in the differential…
