| Summary: | OBJECTIVES AND BACKGROUND
The aim of this study was to find an alternative to
Transient Elastography when its’ application is impossible
or when no valid and reliable measurements can be
obtained through its usage.
MATERIALS AND METHODS
Liver stiffness values were assessed with transient
elastography [TE- (Fibroscan)], 2D shear wave
elastography (SuperSonic Shear Imaging-SSI) and point
shear wave elastography (pSWE) using VTQ and
ElastPQ, in a cohort of 90 patients with chronic liver
diseases. With the help of linear regression, we made a
multivariate analysis in order to test the relationship
between TE and the other three methods (ElastPQ, SSI,
VTQ). Given the very well correlated factors, we
consider them predictors for our model.
RESULTS
The model conducted with all the used factorsElastPQ+SSI+VTQ
compared with TE explained the
90.7% of the model variability (R=0.907). We tempted
the probability to exclude the factors one by one.
SSI+VTQ explained 90% of the model variability
(R=0.90). ElastPQ+VTQ explained 77% of the model
variability (R=0.77) and SSI+ElastPQ explained 89% of
the model variability (R=0.89).
CONCLUSIONS
SSI in combination with ElastPQ or VTQ is as good
as the TE single use. Therefore, these combinations can
be applied when TE can’t be performed or is not valid.
