Ultrasound diagnosis (ultrasound)

Ultrasound of the portal vein system

The portal vein is formed from the fusion of the superior mesenteric vein and the splenic vein. The latter departs from the gates of the spleen and goes along the posterior edge of the pancreas, accompanying the same artery. The pattern of intrahepatic branching and hepatic veins is determined by the segmental structure of the liver. The anatomical diagram shows the type of liver in front. MP angiography in the coronal plane is an alternative technique for visualization of the portal vein system.

Ultrasound of the inferior vena cava and hepatic veins

The lower hollow vein is located to the right of the spine, passing through the diaphragm, and falls into the right atrium. The main inflows visualized with ultrasound dopplerography are iliac veins, renal veins and three hepatic veins that flow into the lower vena cava immediately below the diaphragm.

Ultrasound of the arteries of the internal organs of the abdominal cavity

The arteries of the internal organs of the abdominal cavity should be examined on an empty stomach. Scanning with a full expiration gives a better picture than with a full breath. The results are documented by spectral traces, and the measured blood flow velocities are interpreted in accordance with the blood flow in the aorta.

Ultrasound of the aorta

Visualization of blood flow with the help of ultrasound dopplerography (ultrasound) has expanded the possibilities of the ultrasound method for examination of the abdominal cavity organs. Ultrasonic dopplerography is performed according to certain clinical indications, requiring a specific protocol for the study and quantification of blood flow, for example, after monitoring after interventional interventions for the imposition of a transient intrahepatic portosystemic shunt.

Ultrasound of the thyroid gland

Vascularization of the thyroid gland can be assessed with color flow and pulse dopplerography. Depending on the clinical task (diffuse or focal thyroid disease), the aim of the study may be to quantify the vascularization of the thyroid gland or to determine its vascular structure.

Ultrasound of the lymph nodes of the neck

The lymph nodes of the neck are superficially placed, so they can be visualized using a high-frequency (5-10 MHz) linear sensor. The accessibility of the lymph nodes of the neck to a detailed examination broadens the range of diagnostic criteria as compared to ultrasound examination of the lymph nodes of the abdominal cavity.

Dopplerography of cerebral vessels

The main goal of the study of cerebral vessels with the use of color duplex sonography is to determine and quantify the degree of stenosis caused by atherosclerotic changes in patients with complaints and transient ischemic attack or stroke in the anamnesis. The study should establish the degree of stenosis and the extent of the affected segment of the vessel.

Malignant tumors of the mammary gland

If you suspect a malignant process, the ultrasound of the mammary glands allows you to estimate the location, quantity, size, shape, echostructure, contours, additional acoustic effects, the condition of the ducts and surrounding tissues, including skin changes, and the presence and nature of vascularization.

Ultrasound of the mammary glands

The most common method of examining the mammary glands all over the world is X-ray mammography. In our country, x-ray mammography is still the leading diagnostic method, although in other countries it is successfully used with ultrasound or ultrasound mammography (breast ultrasound).

Ultrasound of the penis

The ultrasound of the penis makes it possible to detect structural changes in the organ. Namely, spongy and cavernous bodies, shells. The investigation is carried out by an ultrasonic sensor with a frequency of at least 7 MPa in transverse and longitudinal sections.
