Atomic nuclei, their structure, properties and behavior characteristics under certain conditions have been the subject of increased scientific interest and the subject of many studies since the inception of nuclear physics as an independent branch of science. In the mid-twentieth century, two independent groups of scientists led by F.

Electroencephalography, also called EEG, is a method used to study the state of the human brain and is based on recording its electrical activity. This examination allows you to detect the spread of pathological processes, signs of epilepsy. The average duration of the procedure is about an hour, however, it is highly informative, makes it possible to track any changes in the brain, the dynamics of the disease, to evaluate the impact of ongoing therapy.
To date, one of the main methods of diagnosing heart disease is echocardiography (echocardiography). This is a non-invasive study that does not have a negative effect on the body, and therefore can be conducted for patients of all ages, including children from birth. What is an echocardiography, what is it for, what types of this procedure exist, what can be a contraindication for its implementation and how it is necessary to prepare for it, will be discussed in this article.
Enteroscopy, as one of the types of medical endoscopy, is aimed at a visual inspection of the most remote from the point of view of access section of our body - the small intestine. For years, the only way to study the small intestine was fluoroscopy, accompanied by the reception of a contrast agent.
Ultrasound examination is a simple, fast and informative method. It has virtually no contraindications and is painlessly tolerated even by the smallest patients. The elbow joint is small in size, located relatively superficially, so it is most convenient to examine it using ultrasound.
The lymph node is a component of the lymphatic system that performs certain functions. He participates in the formation of immunity, produces antibodies that are necessary to protect the body. In addition, the lymph node is a barrier to foreign microorganisms and is considered a natural "filter".
Ultrasound is a research method that does not cause any special concerns and fear in patients. Usually, a person, without hesitation, goes on research and understands that it is completely safe and painless. It is important to note that the safety, painlessness and relative comfort of the study do not affect the accuracy of the result and the seriousness of the method.
Diagnosing pathology and damage to the knee joint, often external examination of the knee is not enough. To make an accurate diagnosis, it is necessary to visually inspect the internal elements of the joint. In this case, specialists use various methods: MRI, X-ray, arthroscopy, ultrasound diagnosis of the knee joint.
Salivary glands are the glands of the oral cavity that are responsible for the secretion of saliva. This is a clear, colorless liquid (liquid biological environment of the body) that moistens the oral cavity, helps a person to perceive taste, and helps the process of swallowing. Moreover, saliva has a bactericidal effect and protects teeth from multiple injuries from pathogens.
Examination of the stomach has always been a challenge. In order to assess the condition of the mucous membrane and to have the most complete picture of the function of the stomach and duodenum, gastric sounding is performed. What is such a diagnostic method? How to prepare for the procedure? What indications and contraindications are there for sounding?
Functional magnetic resonance imaging is a type of classical MRI. The difference between these two similar techniques is that the first version is necessary to identify hemodynamic parameters. We are talking about checking for possible changes in blood flow during the activation of special zones located in the brain.
Sometimes, for a more accurate diagnosis and identification of various pathologies, the attending physician may prescribe a duplex scan or dopplerography of the penile vessels. What is characterized by this procedure? Is it necessary to prepare in a certain way for its implementation? What contraindications does she have?
Ultrasound diagnosis is a universal diagnostic method that is used in various fields of medicine. Until recently, it was rather difficult to examine the intestines, and ultrasonography was practically not used in proctology. This is explained by the fact that the lumen of the intestine contains gas that distorts the image.
The hip joint is a component of the musculoskeletal system of the human body. The joint is responsible for the activity of the thigh (circular rotation / flexion / extension / abduction / reduction) and allows the person to maintain balance. Bone junction undergoes many pathologies - from mechanical damage to cancerous tumors or inflammatory processes.
The cervical spine consists of seven vertebrae. The constituent elements (bones) of the department are small, since they are subject to maximum mobility and minimal load. The main function of the vertebrae is to control the activity of head movements. The cervical spine can be subjected to a huge number of diseases - from anatomical features to mechanical injuries or the appearance of hernias.
The term "polycardiography" comes from three words of Greek origin: "poly" is a lot, "kardio" is a heart, and "grapho" is to represent. Polycardiography is a combined method of studying the functions of the heart, which combines the simultaneous electrocardiography (ECG), phonocardiography (PCG) and sphygmograms of the carotid artery (CCA).
Ultrasound examination of the shoulder is a quick, relatively cheap and dynamic way of examining the shoulder joint and it is especially useful in the diagnosis: impaired function of the shoulder, instability of the shoulder, impaired rotational ability of the shoulder joint. The study requires attention to the technique and the appropriate positioning of the patient.
Electromyography (EMG) is a modern method for diagnosing the activity of muscle tissue. The technique used to determine the functional abilities of nerves, muscles and soft tissues. With the help of EMG, the degree of damage after trauma is diagnosed or the dynamics of long-term treatment of muscle tissue is determined.
Everyone knows that the general condition of a person directly depends on the healthy activity of all organs and systems in the body. A major role in the body is performed by the endocrine system, and in violation of the function of the endocrine glands, dysfunction occurs in virtually all internal organs. That is why it is very important to seek help from an experienced specialist at the very first clinical symptoms and complaints.
Ultrasound (ultrasound examination) of the pelvic organs in men is a medical imaging technique that allows you to view the insides of the human body. This is done using a transducer, also called a sensor, which emits high-frequency sound waves (ultrasounds).
Electrocardiography is a diagnostic method used to study the function of the heart and cardiovascular system. The main advantages of the procedure are accessibility and informational content. To perform the procedure, it is sufficient to have an apparatus and a specialist who knows the execution methodology. Special conditions are not required - ECGs are done in medical institutions at all levels.
