Факторы, оказывающие влияние на результаты ультразвуковой эластометрии печени

Факторы, которые оказывают влияние на результаты ультразвуковой эластометрии, имеют большое значение при интерпретации данных в рамках диагностики фиброза печени. При использовании ультразвуковой эластометрии в других целях (например, при прогнозировании сердечных событий у пациентов с правосторонней сердечной недостаточностью, мониторинге пациентов с синдромом синусоидальной обструкции печени, мониторинге краткосрочных и долгосрочных результатов ангиопластики у пациентов с синдромом Бадда-Киари) учет факторов, искажающих результаты эластометрии, также необходим. Факторы, искажающие результаты эластометрии, связаны с методикой исследования, оборудованием, артефактами, особенностями состояния организма и внешними воздействиями. Многие из них носят универсальный характер независимо от используемого вида количественной ультразвуковой эластографии. Наличие факторов, искажающих результаты эластометрии, следует отражать в протоколе эластографического исследования печени и оценивать при написании заключения, вплоть до указания о невозможности интерпретации полученных результатов.
