Purpose
The heterogeneous group of rheumatic diseases,
known under the name of seronegative spondyloarthropaties (SpA) or spondyloarthritis,
divides in two categories: axial (axSpA) and peripheral spondyloarthritis (pSpA).
In the first type,
axial skeleton is predominantly involved,
while in the second,
only peripheral manifestations of the disease are observed.
There is still the need for the search of techniques which increase the diagnostic accuracy of the axSpA in the early stage.
One of possible techniques is multiparametric MRI,
which,
apart from standard sequences,
consists of methods such as diffusion-weighted imaging (DWI) and dynamic contrast-enhanced (DCE) perfusion imaging.
Nonetheless,
the consensus regarding its use in the diagnostics of axSpA has not been reached yet,
due to the limited evidence and contradictory results of previous research.
The aim of the study was to assess the diagnostic performance of the visual assessment of DWI sequence with ADC maps and DCE sequence in the detection of active sacroiliitis in the course of axSpA,
in comparison to the standard STIR sequence.
