Ultrasound diagnosis (ultrasound)

Doppler ultrasound in obstetrics

In recent years, dopplerography has become one of the leading methods of research in obstetrics. The essence of the Doppler effect is as follows. Ultrasonic vibrations generated by piezoelements with a given frequency propagate in the object under study in the form of elastic waves.

Cardiotocography

At present, cardiotocography (CTG) is the leading method for assessing the functional state of the fetus. There are indirect (external) and direct (internal) cardiotocography.

Echography in Obstetrics

Currently, echography is the leading method of obstetrics research. The use of modern equipment allows you to determine the pregnancy already at 4.5 weeks (counting from the 1st day of the last menstruation).

Echoencephaloscopy

Echoencephaloscopy (Echo, synonym - M method) is a method for detecting intracranial pathology based on the echolocation of the so-called sagittal structures of the brain, normally occupying a middle position with respect to the temporal bones of the skull. When a graphic recording of the reflected signals is made, the study is called echoencephalography.

Ultrasonic dopplerography of vessels

The great importance of stenosing and occlusive lesions of the main arteries of the head in the pathogenesis of cerebrovascular diseases is well known. In this case, not only the initial, but also severe stenosis of the carotid and vertebral arteries can proceed little. In the development of angioedema pathology is important and the contribution of venous dyskirkulyatsii, also sometimes taking place subclinically.

Transcranial Doppler

In most cases of diagnostic use of ultrasound dopplerography, it should be carried out together with transcranial dopplerography. The exception to this rule is made up of persons with insufficiently pronounced or completely absent "temporal" windows, as well as patients who are unable to perform transcranial dopplerography for other reasons (7-12% of the total number of subjects).

Duplex scanning of vessels of the head and neck

Duplex scanning (gray-scale echography with color Doppler coding and spectral Doppler analysis, applied to the intracranial part of the cerebral vasculature - transcranial duplex scanning) currently serves as the main method for diagnosing various types of pathology of the cerebral vascular system.

Ultrasound signs of uterine pathology

Currently, given the widespread introduction into clinical practice of transvaginal ultrasound, the diagnosis of pathological changes in the myometrium does not present significant difficulties. However, the informativity of ultrasonic diagnostics for different pathologies of the myometrium is not the same.

Ultrasound of the pelvic organs and uterus

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.

Ultrasound of the eye

Ultrasonic studies (ultrasound) in the pathology of the eye and orbit are used extremely widely, since in most cases the only contraindication to their conduct is only a fresh extensive penetrating wound of the eye.
