Ultrasound diagnosis (ultrasound)

Ultrasound of the portal vein system

The portal vein is formed by the confluence of the superior mesenteric vein and the splenic vein. The latter originates from the splenic hilum and runs along the posterior margin of the pancreas, accompanying the artery of the same name. The pattern of intrahepatic branching and hepatic veins is determined by the segmental structure of the liver. The anatomical diagram shows the frontal view of the liver. Coronal MR angiography is an alternative method for visualizing the portal vein system.

Ultrasound of the inferior vena cava and hepatic veins

The inferior vena cava is located to the right of the spine, passing through the diaphragm and emptying into the right atrium. The main tributaries visualized by Doppler ultrasound are the iliac veins, the renal vein, and the three hepatic veins, which empty into the inferior vena cava just below the diaphragm.

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

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

Aortic ultrasound

Blood flow visualization using ultrasound Dopplerography (US) has expanded the capabilities of the ultrasound method in examining abdominal organs. Ultrasound Dopplerography is performed according to certain clinical indications that require a specific examination protocol and quantitative assessment of blood flow, for example, during monitoring after interventional procedures for the imposition of a transjugular intrahepatic portosystemic shunt.

Thyroid ultrasound

Thyroid vascularization can be assessed using color flow and pulse Doppler. Depending on the clinical task (diffuse or focal thyroid disease), the purpose of the study may be a quantitative assessment of thyroid vascularization or determination of its vascular structure.

Neck lymph node ultrasound

The lymph nodes of the neck are located superficially, and therefore they can be visualized using a high-frequency (5-10 MHz) linear sensor. The availability of the lymph nodes of the neck for detailed examination expands the range of diagnostically significant criteria compared to ultrasound examination of the lymph nodes of the abdominal cavity.

Dopplerography of cerebral vessels

The primary objective of cerebral vascular examination using color duplex sonography is to determine and quantify the degree of stenosis caused by atherosclerotic changes in patients with complaints and a history of transient ischemic attack or stroke. The examination should establish the degree of stenosis and the extent of the affected vessel segment.

Malignant breast tumors

If a malignant process is suspected, ultrasound of the mammary glands allows one to assess the location, quantity, size, shape, echostructure, contours, additional acoustic effects, the condition of the ducts and surrounding tissues, including skin changes, as well as the presence and nature of vascularization.

breast ultrasound

The most common method of examining mammary glands worldwide is X-ray mammography. In our country, X-ray mammography is still the leading diagnostic method, although in other countries, echography or ultrasound mammography (ultrasound of the mammary glands) are successfully used alongside it.

Penile ultrasound

Ultrasound of the penis allows detecting structural changes in the organ, namely, the spongy and cavernous bodies, membranes. The study is carried out with an ultrasound sensor with a frequency of at least 7 MPa in transverse and longitudinal sections.
