Radiation Exposure to the Sacroiliac Joint From Low-Dose CT Compared With Radiography

Abstract: LD CT of the SIJ can be consistently performed with an effective radiation dose of less than 1 mSv. Because reliability and sensitivity of radiography for sacroiliitis is poor, we recommend that LD CT replace radiography for dedicated evaluation of the SIJ.

“…Fortunately, CT has been developed as an appropriate modality with similar or even lower radiation exposure (lower than 1 mSv) 13 than radiography. At the same time, it has been proved to be more sensitive than conventional radiographs (X‐rays) in monitoring disease progression in patients with AS, according to reports in the Annual European Congress of Rheumatology (EULAR) in 2017.…”

“…Low-dose CT approaches have been developed that permit three-dimensional (3D) evaluation of the sacroiliac joints with a radiation dose comparable with plain radiography. 39 , 40 Moreover, the development of new MRI techniques that support the detection of structural lesions is an active field. A recent study found that susceptibility-weighted imaging (SWI) in patients with axSpA depicts erosions and sclerosis more accurately than standard T1-weighted imaging using CT as a reference standard.…”
