METHOD FOR EXPRESS DETERMINATION OF LIVER ALVEOCOCCOSIS ACTIVITY BY ULTRASONIC EXAMINATION WITH ECHO CONTRAST Russian patent published in 2019 - IPC A61B8/08 A61K49/22 A61P43/00 

FIELD: medicine.

SUBSTANCE: invention relates to radiation diagnostics, medical parasitology and infectious diseases, and can be used for rapid determination of hepatic alveococcosis activity by ultrasonic analysis with echo contrast. Method includes ehocontrast substance in dose of 2.5 ml into a central vein with subsequent introduction of 10 ml of normal saline. Examination is started at the moment of introducing normal saline and is performed for a time sufficient for recording the arterial and venous phases. Presence of accumulation of echoes in formation, which is a parasitic node, contrasting of a peri-parasitic infiltrate, vessels feeding into a parasitic node is evaluated. If the echonastic substance does not accumulate in the structure of the formation, the peri-parasitic infiltrate is contrasted, the vessels feeding into the parasitic node are not detected, the inactive alveococcus is determined. If the echonastic substance does not accumulate in the structure of the formation, the periparasitic zone is not contrasted, the vessels delivering the parasitic node are determined, the active form of alveococcus is determined.

EFFECT: method provides a non-invasive rapid determination of the activity of alveococcal liver involvement by ultrasonic examination with echo contrast, start of echocontrasting at the moment of introduction of physiologic saline and its carrying out during arterial and venous phases.
