An Imaging Review of Sacroiliac Joint Injection Under Computed Tomography Guidance

Navigating the Murk: Ethical and Practical Considerations for the Surgical Treatment of the Sacroiliac Joint Syndrome

“…Traditional imaging has not yet been proven to be informative, however single photon emission computed tomography (SPECT-CT) may be informative in cases where objective imaging is considered. 33 Intra-articular injections may be helpful in diagnostic testing, although CT-guided injections have been reported to be superior in accuracy to fluoroscopic guidance 34 and may provide sufficient therapeutic response. 35 Sacral branch blocks may provide added diagnostic benefit, although the therapeutic benefits are not as clear.…”

“…A leaping off point for diagnosis would be diagnostic injections-but this route is not entirely benign. CT-guided injection may be more accurate than fluoroscopic injection based upon seemingly higher outcomes in noncomparative studies, 34,40,54 but brings with it elevated radiation risk. Even our best diagnostic tool is only 70% accurate 55,56 and is therefore, not final.…”

“…However, they carry substantial risk of ionizing radiation for the patient and for the physician, and moreover they require an additional appointment at another department, as well as there is a potential risk of allergic reaction to the contrast media [8]. The Computer tomography (CT) guided injections are accurate but also require complex settings and equipment and involve radiation exposure [9]. Most of these holds true also for magnetic resonance imaging (MRI) assisted sacroiliac injections.…”
