It happens that a woman can not get pregnant. To clarify the cause, it is necessary to conduct an examination, including an x-ray of the fallopian tubes.
Pain in the knee, impaired mobility of the joint in this area and traumatic injuries are quite frequent reasons for contacting a doctor. Determine by eye, with which unpleasant symptoms are associated, it is not easy even for an experienced doctor.
In the 1980s, computer methods of imaging were introduced into the practice of cardiology: digital coronary and ventriculography, computed tomography synchronized with heart function, magnetic resonance imaging. Moreover, radiologists have received special catheters for vascular plastic and laser devices for evaporation of atherosclerotic plaques.
Rheoencephalography (REG) is based on the measurement of changes in the impedance of the head associated with the pulse wave when a weak high-frequency electric current passes through the electrodes.

To evaluate vegetative functions in many cases, a careful analysis of the patient's complaints and anamnestic information about the function of the genitourinary and rectum, the presence of excessive sweating, mandatory urination, urinary incontinence and erectile dysfunction (in men) is sufficient in many cases.

In the study of the autonomic nervous system, it is important to determine its functional state. The principles of research should be based on the clinical-experimental approach, the essence of which is the functional dynamic studies of tone, vegetative reactivity, vegetative support of activity.

A deep (miotatic) reflex is an involuntary contraction of the muscle in response to stimulation of the muscle spindle receptors contained in it, which in turn is due to passive stretching of the muscle. Such stretching in clinical practice is usually achieved by a short, abrupt impact of the neurological malleus over the muscle tendon.

The strength of the muscle is a quantitative measure that expresses the ability of the muscle to contract during counteraction to its external force, including gravity. Clinical research of muscle strength first of all reveals its decrease. A preliminary, tentative evaluation of muscular strength begins with finding out whether the subject can carry out active movements in all joints and whether these movements are carried out in full.

In the clinical practice of a neurologist, the evaluation of cognitive functions includes the study of orientation, attention, memory, counting, speech, writing, reading, praxis, gnosis.

Indications for tonsillectomy (removal of tonsils) are quite numerous, but there are no fewer contraindications to this surgical intervention. Failure to comply with strict indications (contraindications) to tonsillectomy (removal of tonsils) and its conduct often turns a patient with a relatively favorable course of chronic tonsillitis
Complications of colonoscopy are very rare. There is a perforation of the colon, bleeding. In these cases urgent surgical intervention is necessary.
Depressingly long seemed the distance between physical laboratories, where scientists registered tracks of nuclear particles, and everyday clinical practice. The very idea of the possibility of using nuclear-physical phenomena for the examination of patients could seem, if not insane, then fantastic. However, exactly such an idea was born in the experiments of the Hungarian scientist D.Heveshi, later the Nobel Prize winner.
Radionuclide is an unstable isotope, which becomes more stable when energy is released in the form of radiation (nuclear decay). This radiation can include particulate emission or y-ray photons.
Modern medical disciplines are impossible without interaction with related specialties, especially diagnostic ones. Successful treatment and its prognosis depend to a large extent on the quality and accuracy of the diagnostic tests.
Radiography (X-ray imaging) is an X-ray examination method in which a fixed X-ray image of an object is obtained on a solid carrier, in the overwhelming majority of cases on an X-ray film.

Radiation, or imaging, research methods occupy an important place in the diagnosis and differential diagnosis of kidney disease. Their role has especially increased in recent years due to the technical improvement of methods, which significantly increased their resolution and safety.
