“…Applying a single limit is not practical and reported radiation exposures vary widely. For example, reported mean exposure dose for pelvis ldCT [1] was three times another recent report [2] and 47 times the dose of a dedicated SIJ protocol [3 ▪▪ ]. This latter study confirmed that by using tin filtration, SIJ ldCT radiation dose can be reduced even further to 0.11 mSv, which is the same dose as PA and lateral chest radiography, while maintaining diagnostic quality.…”

Purpose of reviewRecent developments in low-dose computed tomography (ldCT) have greatly reduced radiation exposure levels. This article reviews what a ldCT is and its use and limitations for imaging axial spondyloarthritis. Recent findingsDetection of structural damage in bone with CT is far superior to radiography and ldCT of the sacroiliac joints (SIJ) can now be done at radiation exposure levels equivalent to, or even less than, conventional radiography. ldCT should be considered a 'first-choice' test for arthritis imaging, and wherever available, SIJ ldCT may completely replace conventional radiography. Radiation exposure in the spine with ldCT is lower than conventional CT. However, it is unclear whether the additional information regarding structural damage changes in the spine provided by ldCT will alter patient management sufficiently often to merit switching from spinal radiography to ldCT in routine clinical practice. In addition, ldCT cannot assess osteitis disease activity for which MRI remains the best test.Summary ldCT of the sacroiliac joints (SIJ) can be done at radiation exposure levels equivalent to, or less than, radiography and ldCT may completely replace SIJ radiography. However, the role of spinal ldCT for spondyloarthritis is not clear and MRI is far superior for detecting disease activity.
