Recommendations
As issued by the authors
A minimum four-sequence IAP is recommended for diagnostic ascertainment of sacroiliitis and its differential diagnoses
Three semicoronal sequences, parallel to the dorsal cortex of the S2 vertebral body, sensitive for: (1) changes in fat signal and structural damage with T1-weighting; (2) active inflammation, T2-weighted with fat suppression; (3) bone erosion optimally depicting the bone-cartilage interface of the articular surface
(4) a semiaxial sequence sensitive for detection of inflammation
