“…A noninvasive diagnostic test that yields results comparable to pathologic evaluation would be helpful for supporting future studies of degenerative sacroiliac joint disease in dogs. Previous human studies have established CT as a sensitive modality for detecting degenerative sacroiliac joint disease lesions and have described the CT characteristics of these lesions . One of these studies compared pelvic plain radiography, abdominal CT, and sacroiliac joint MRI methods for detecting presence of sacroiliitis in a group of humans .…”

Degenerative sacroiliac joint disease is a cause of lumbosacral pain in dogs; however, published information on cross‐sectional imaging characteristics is limited. Objectives of this retrospective, secondary analysis, methods‐comparison study were to test hypotheses that CT lesions reported in humans with degenerative sacroiliac joint disease are also present in dogs, and that CT is comparable to gross pathology for detecting these lesions. Matched CT and gross pathology slice images of 30 sacroiliac joints were retrieved from a previous prospective, canine cadaver study. A veterinary radiologist interpreted randomized CT images for each joint based on previously published CT characteristics of lesions in humans with degenerative sacroiliac joint disease. A veterinary pathologist independently interpreted randomized gross pathology images using the same criteria. All joints had at least one CT lesion consistent with degenerative sacroiliac joint disease. A new CT lesion was also identified and termed “subarticular cleft.” The CT and gross pathology methods agreed for detecting joints with subchondral sclerosis, subchondral erosion, and intra‐articular ankylosis lesions (P > .05, McNemar's test), but disagreed for detection of joints with subchondral cyst, para‐articular ankylosis, and subarticular cleft lesions (P ≤ .05). Using gross pathology as the reference standard, CT had 100% sensitivity for detection of subarticular cleft and subchondral cyst lesions, with 56% and 22% specificity, respectively. Para‐articular ankylosis lesions were detected by CT but not by gross pathology. Findings supported the hypothesis that CT lesions reported in humans with degenerative sacroiliac joint disease are also present in dogs, and partially supported the hypothesis that CT is comparable to gross pathology for detecting joints with these lesions.

Background Structural lesion evaluation in axial spondyloarthropathy (SpA) can improve accuracy of diagnosis. However, structural lesions (bone erosions) are difficult to be assessed using conventional MRI compared to computed tomography (CT). Purpose To evaluate the diagnostic performance of ultrashort echo time (UTE) for detecting bone erosion in axial SpA compared to T1WI and three‐dimensional double‐echo steady‐state (3D DESS) imaging using CT as the reference standard. Study Type Retrospective. Population Fourteen patients (eight females, 57.1%) and 14 healthy controls (seven females, 50.0%) who underwent sacroiliac (SI) joint MRI and CT. Field Strength/Sequence 3 T; TSE T1WI, 3D DESS, 2D UTE. Assessment The bilateral SI joints were assessed for bone erosion. Three observers scored bone erosion for all three sequences of MRI. CT was used as the gold standard. Diagnostic confidence in axial SpA was measured based on a four‐point confidence score. Statistical Tests Correlation of erosion scores between CT and MRI were evaluated using Spearman's correlation test. Sensitivity, specificity, and positive–negative predictive values were calculated. Confidence scores were compared using the Wilcoxon sum rank test. Statistical significance was set at P < 0.05. Results Compared with erosion scores of CT, the correlation coefficients for each MRI sequence showed significant low‐to‐high positive correlations (0.39–0.72). UTE imaging showed the highest correlation coefficients for all observers (0.70, 0.72, and 0.67, respectively). The specificity of UTE imaging was equal or higher than those of T1WI and 3D DESS for all observers (0.86 vs. 0.71 vs. 0.57; 0.93 vs. 0.71 vs. 0.57; 0.79 vs. 0.79 vs. 0.43). All observers had the highest confidence in interpreting UTE imaging for detecting bone erosion among the three sequences (3.5, 3.4, and 3.3 for UTE; 3.1, 3.0, and 2.6 for T1WI; and 3.2, 2.7, and 2.4 for DESS). Data Conclusion UTE imaging can detect bone erosions in patients with axial SpA and show higher specificity than conventional T1WI and 3D DESS. Evidence Level 4 Technical Efficacy Stage 2
