    Results of the ultrasound and morphological examination of the villous chorion of women with physiological pregnancy (34 cases) and with late pregnancy toxicoses (280 cases) were compared. A gradual decrease of the chorion acoustic density in physiological pregnancy correlates with a development of the compensatory-adaptive reaction (CAR) on the tissue level and serves a favourable prognosis for the pregnancy outcome. In patients with late pregnancy toxicosis, alterations of the chorion echogenicity occur at different periods of the pregnancy and reflect the CAR disturbances facilitating the development of various forms (stages) of the placenta insufficiency. The results obtained indicate possibilities of placentography use for a differential approach to the choice of methods and terms of delivery in late pregnancy toxicoses.

    Ultrasonography

    Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.

    Ultrasound I: Abdominal Ultrasonography

    Introduction:
    Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
    Procedure:
    This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
    The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
