The First Results of the Application of Shear Wave Transient Elastography When Determining the State of Pancreatic Parenchyma (Review of Literature and Own Researches)
Journal Title: Гастроентерологія - Year 2015, Vol 3, Issue 57
Abstract
Elastography is a rapidly developing diagnostic me-thod and enables to identify and to differentiate focal masses of different origin, as well as the stage of fibrous transformation of the liver, as evidenced by many research works. The method is firmly established in the practice of gastroenterology. The appearance of a new generation devices with the function of ARFI (VTQ) and SWEI has allowed scientists to begin a transient study of the stiffness of pancreatic parenchyma. However, there is small quantity of these works, it is necessary to standardize the technique of execution of the research and its results in various diseases. The apparatus Ultima PA Expert® (Radmir, Ukraine) with the function of SWEI enables to conduct transient elastography of the pancreas, when using certain technical methods, in order to determine the stiffness of the parenchyma in normal and in diffuse pathology. The values of the stiffness obtained with the apparatus Ultima PA Expert® (Radmir, Ukraine) presented in kPa and at the same time in m/s, making these data comparable with those obtained by other researchers on the devices having only one measurement function. In apparently healthy individuals, we have received the parameter of the stiffness of pancreatic parenchyma of (4.86 ± 0.05) kPa, (1.33 ± 0.05) m/s. In chronic pancreatitis, this measure is (6.48 ± 0.80) kPa, (1.52 ± 0.17) m/s. The findings make it possible to determine the therapeutic approach, as well as its effectiveness, based on the indicators of stiffness.
