Computerized tomography (CT) severity scores are frequently used as an objective staging tool in chronic rhinosinusitis (CRS). Magnetic resonance imaging (MRI) has also been proposed as a valid option in CRS imaging.
The aim of this systematic review was to briefly present the recent developments on sinus imaging utilized in clinical practice with regard to diagnostic accuracy of imaging and severity staging in CRS according to evidence-based medicine (EBM) principles.
This review paper has been assembled following PRISMA guidelines. A PubMed and Scopus (EMBASE) search using CRS, "severity staging", "diagnostic accuracy "and "imaging "resulted with 80 results. Of these, only 12 (59%) contained original data, constituting the synthesis of best-quality available evidence.
CT is the most commonly used imaging technique for the severity staging of CRS, but a question of higher cumulative radiation dose should be taken into consideration when repeating CT examinations in evaluating treatment efficacy. MRI may be a complementary diagnostic and staging tool, especially when repeated examinations are required, or when paediatric CRS patients are evaluated. The severity staging system may be improved to better correlate with subjective scores.
MRI may be utilized as a staging tool with comparable diagnostic accuracy, using the same staging systems as with CT examinations.
计算机断层扫描（CT）严重程度评分常被用作慢性鼻-鼻窦炎（CRS）的客观分期工具。磁共振成像（MRI）也被提议作为 CRS 成像的有效选择。
本系统评价的目的是简要介绍鼻窦成像在临床实践中的最新进展，根据循证医学（EBM）原则，就成像的诊断准确性和 CRS 的严重程度分期进行介绍。
本综述论文遵循 PRISMA 指南进行汇编。使用 CRS、“严重程度分期”、“诊断准确性”和“成像”在 PubMed 和 Scopus（EMBASE）进行搜索，共得到 80 个结果。其中，只有 12 个（59%）包含原始数据，构成了最佳质量证据的综合。
CT 是 CRS 严重程度分期最常用的成像技术，但在评估治疗效果时重复 CT 检查时应考虑到累积辐射剂量更高的问题。MRI 可能是一种补充的诊断和分期工具，特别是在需要重复检查时，或在评估儿科 CRS 患者时。严重程度分期系统可以得到改善，以更好地与主观评分相关联。
MRI 可用作具有可比诊断准确性的分期工具，使用与 CT 检查相同的分期系统。
