Ultrasound diagnosis (ultrasound)


Echocardiography is the most important technique in the diagnosis of various structural and / or functional changes in the heart. Echocardiography accurately displays the anatomical details, it is possible to measure the structure of the heart, and their movements are clearly traced throughout the heart cycle.

Ultrasound of the upper limb

Thrombosis most often affects the subclavian vein. Since the vein is located behind the clavicle, a sample with compression can not be performed. It is also difficult to squeeze the proximal and middle third of the axillary vein. Therefore, the main criterion for diagnosis of venous thrombosis of the upper limb is the detection of a lack of color blood flow.

Ultrasound of the veins of the lower extremities

Various venous pools of the upper and lower extremities are characterized by different pathophysiological mechanisms and are discussed in different sections. The method of examination should correspond to the anatomy of the vessels.

Doppler ultrasonography of the arteries of the lower extremities

Diagnosis of peripheral arterial diseases of the extremities is based on a clinical examination involving Ratcshow or Allen samples, pulse estimation, walking time and measurement of the ankle-brachial index (LIP). Based on the results of these studies, indications for a color duplex sonography of the arteries of the limb are determined.

Dopplerography of Fallopian tubes

Ultrasonic dopplerography of the fallopian tubes plays an additional role in the diagnosis of ectopic pregnancy, since fetal activity can be detected only in 10% of cases.

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.
