Use of SPECT/CT (Single Photon Emission Computed Tomography/Computed Tomography) is increasing providing additional information in patients with inconclusive clinical examination and unremarkable imaging findings presenting with chronic pain after total ankle arthroplasty. To differentiate the cause of pain after total ankle arthroplasty can be challenging. SPECT/CT combines structural and metabolic imaging as a hybrid tool leading to higher specificity and overall diagnostic accuracy presumably in cases of gutter impingement, prosthetic loosening, and osteoarthritis of adjacent joints. Moreover, SPECT/CT can complement diagnostic work up in periprosthetic joint infections. Basal tracer enhancement has to be considered for the interpretation of imaging findings.
SPECT/CT（单光子发射计算机断层扫描/计算机断层扫描）的使用越来越多，为临床检查结果不确定且影像学表现无明显异常、全踝关节置换术后出现慢性疼痛的患者提供了更多信息。鉴别全踝关节置换术后疼痛的原因具有一定挑战性。SPECT/CT 将结构成像和代谢成像结合为一种混合工具，据称在关节突撞击、假体松动和相邻关节骨关节炎的情况下，可提高特异性和整体诊断准确性。此外，SPECT/CT 可补充假体周围关节感染的诊断。在解释影像学发现时，必须考虑基础示踪剂增强。
