Bundles are fibrillar structures that connect two bone structures to each other. There are two types of ligaments: intraarticular and extraarticular. This difference defines a differentiated approach to their investigation. Since ultrasound examination of intraarticular ligament is difficult due to bone structures, the MRI method is used to evaluate them.

Uroflowmetry is a non-invasive screening test for detecting possible dysfunction of the lower urinary tract. In her, the parameters of the flow of urine are measured.

Urodynamic studies (UDI) are classified as the main methods of functional diagnostics in urology. Their theoretical basis is the principles and laws of hydrodynamics. Registration and calculation of research parameters are based on this section of physics.
Urethroscopy is one of the methods for examining the urethra and performing some medical manipulations (examination of the urethra) using an optical device - the urethroscope.
Urethrocystoscopy - examination of the urethra and bladder with an endoscope (cystoscope).
Not every effusion or abscess should be punctured under ultrasound control, but it is important to use echography when puncturing the lesions located next to vital organs. Ultrasound is used to select the shortest distance to the object and the safest trajectory of passing the needle.
The ultrasonic method (US) has a number of advantages over magnetic resonance imaging in the study of soft tissues of wrist joints and hand joints. There are several points that emphasize these advantages. First, it is the convenience of carrying out ultrasound and the ability to quickly compare the symmetrical departments.
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.
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.
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.
Indications for ultrasound of the spleen: splenomegaly (enlarged spleen), formation in the left half of the abdomen, closed abdominal injury.
Indications for ultrasound of the pelvis: Pain in the pelvis, including algodismenore (painful menstruation). Education in a small pelvis. Acyclic uterine bleeding.
The thickness of the skin varies depending on the location, it is larger in men than in women. The subcutaneous fat layer, as a rule, looks hypoechoic with alternating hyperechoic thin fibers reflecting connective tissue interlayers
In most medical institutions, the X-ray examination of the shoulder joint remains, as before, mandatory in the algorithm for the study of patients with shoulder pathology. It is well known that X-ray research is highly informative in the search for traumatic injuries of bone structures.
Ultrasound of the prostate (prostate gland) allows you to get an idea of its size, shape, structure, as well as the peculiarities of its relationship with other pelvic organs.
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.
Pleural effusion is hypoechoic or mild echogenicity, sometimes thick septa are defined. Liquid blood and pus are also anechogenous, but septums can give reflections. It is not always possible to differentiate the fluid and solid formations of the pleura or peripheral parts of the lungs. Turn the patient to different positions and repeat the test.
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.
Indications for ultrasound of the pancreas: pain in the epigastric region, acute and chronic, jaundice, formation in the upper part of the zyvote.
Ultrasound (echography) of pelvic organs belongs to a leading role in a complex of diagnostic methods. This is due to the non-invasiveness, relative simplicity and high informative nature of the method.
