Value of Whole-body SPECT-CT CzT-based Camera (VERITON-CT) in the Assessment of Chronic Inflammatory Rheumatism With Axial Involvement

The diagnosis of chronic inflammatory rheumatism with axial involvement is not always easy, and is fraught with difficulties : radiological sacroiliitis is not an early sign of spondyloarthritis and the delay in detecting radiological signs contributes to the delay in diagnosis. Nevertheless, spondyloarthritis is now the second most common chronic inflammatory rheumatic disease, affecting 0.43% of the french population. The aim of this retrospective study is to evaluate the diagnostic performance of whole-body SPECT-CT CzT-based camera (VERITON-CT) in the assessment of chronic inflammatory rheumatism with axial involvement MRI of the sacroiliac joints and thoracolumbar spine were used as a gold standard.
