Abstract:
OBJECTIVES:To assess increased sacroiliac joint (SIJ) uptake on 18F-NaF PET/CT according to a qualitative and quantitative approach and to compare with MRI SIJ assessments for structural and inflammatory sacroiliitis in a population of 23 patients with spondyloarthritis (SpA) (IDRCB: 2012-A00568-35; ClinicalTrials.gov: NCT 02869100). METHODS:This single-center prospective study included 23 patients with active SpA according to the ASAS and/or modified NY criteria. All patients had a pelvic AP-view radiograph, MRI of the SIJ and 18F-NaF PET/CT examinations within a month, which were analysed by three blinded readers. For MRI data, the SIJs were assessed according to the ASAS criteria and SPARCC method for scoring structural lesions (erosion, sclerosis, fat metaplasia, backfill and ankylosis) and inflammation. On the 18F-NaF PET, the SIJs were scored according to a slice-by-slice approach. Abnormal uptake was assessed using a qualitative method inspired by the ASAS criteria and two quantitative approaches (the PET-activity score according to the SPARCC method and the maximum standardised uptake value (SUVmax) for each SIJ). RESULTS:Structural sacroiliitis was observed on 7 radiographs and 15 MRIs. 10 MRIs showed inflammatory sacroiliitis (mean SPARCC 18.7). Twenty patients had a positive PET with a mean PET-activity score of 18.2 (±8.7). The mean SUVmax for a positive PET was 1.78 vs. 1.45 for a negative one. The inter-reader reliability was good for the PET activity score (ICC= 0.56 [IC-95: 0.32; 0.76]) and good to excellent for the SUVmax (ICC=0.70-0.90 [IC-95: 0.41; 0.96]). According to a binary approach, a positive PET was not correlated with a positive MRI for structural sacroiliitis. The PET-activity score (r=0.61, p=0.001) and SUVmax (r=0.56, p=0.004) were correlated with the SPARCC inflammation score but not with structural sacroiliitis or for SPARCC structural lesions. CONCLUSIONS:Abnormal uptake by the SIJ on 18F-NaF PET is more frequent (87.0%) than inflammatory (43.5%) and structural sacroiliitis (65.2%) on MRI in a population of SpA patients. The PET activity score and SUVmax had good correlations with inflammatory sacroiliitis but not with structural lesions on MRI.
