Abstract
Forty-seven patients with sacroiliac joint abnormalities were examined with computed
tomography and conventional complex-motion tomography. Twenty-nine patients had spondyloarthritis.
Of the 29, complex-motion tomography detected bone erosions in 16 patients, whereas
computed tomography revealed erosions in nine. Computed tomography was more sensitive
in detection of joint narrowing, joint widening, osteosclerosis, and intraarticular
bony ankylosis. In the remaining 13 patients, computed tomography was the modality
of choice in detection of paraarticular soft tissue pathology, such as abscess or
tumor, and in detection of the lesions involving the sacral canal and neura foramina.
