The investigators conducted a review to evaluate the diagnostic performance of multidetector computed tomography (MDCT) for coronary stent evaluation. The prespecified inclusion criteria selected prospective or retrospective human studies published in English. Studies that did not report raw numbers of diagnostic accuracy for the detection of in-stent restenosis were excluded. The data from 24 studies are reported, 6 performed with old-generation scanners (4-, 16-, and 40-slice MDCT) and 18 performed with 64-slice MDCT or dual-source MDCT. With old-generation MDCT, up to 18% of coronary stents were missed, the rate of nonevaluable stents ranged from 2.6% to 23.5%, and the overall feasibility and diagnostic accuracy were 90.4% and 90%, respectively. With 64-slice MDCT, no stent was missed, and the overall feasibility and diagnostic accuracy were 90.4% and 91.9%, respectively. Advancements in MDCT and stent technologies may further reduce the number of nonassessable stents and improve diagnostic performance.
研究者们进行了一项综述，以评估多层螺旋 CT（MDCT）在冠状动脉支架评估中的诊断性能。预定的纳入标准选择了以英文发表的前瞻性或回顾性人类研究。未报告检测支架内再狭窄的诊断准确性原始数据的研究被排除在外。报告了 24 项研究的数据，其中 6 项使用旧一代扫描仪（4 层、16 层和 40 层 MDCT）进行，18 项使用 64 层 MDCT 或双源 MDCT 进行。在使用旧一代 MDCT 时，多达 18%的冠状动脉支架被遗漏，不可评估支架的比例为 2.6%至 23.5%，整体可行性和诊断准确性分别为 90.4%和 90%。在使用 64 层 MDCT 时，没有支架被遗漏，整体可行性和诊断准确性分别为 90.4%和 91.9%。MDCT 和支架技术的进步可能会进一步减少不可评估支架的数量并提高诊断性能。
