Abstract：
Background: Radiomics of salivary gland imaging can support clinical decisions in different clinical scenarios, such as tumors, radiation-induced xerostomia and sialadenitis. This review aims to evaluate the methodological quality of radiomics studies on salivary gland imaging. Material and Methods: A systematic search was performed, and the methodological quality was evaluated using the radiomics quality score (RQS). Subgroup analyses according to the first author\'s professional role (medical or not medical), journal type (radiological journal or other) and the year of publication (2021 or before) were performed. The correlation of RQS with the number of patients was calculated. Results: Twenty-three articles were included (mean RQS 11.34 ± 3.68). Most studies well-documented the imaging protocol (87%), while neither prospective validations nor cost-effectiveness analyses were performed. None of the included studies provided open-source data. A statistically significant difference in RQS according to the year of publication was found (p = 0.009), with papers published in 2021 having slightly higher RQSs than older ones. No differences according to journal type or the first author\'s professional role were demonstrated. A moderate relationship between the overall RQS and the number of patients was found. Conclusions: Radiomics application in salivary gland imaging is increasing. Although its current clinical applicability can be affected by the somewhat inadequate quality of the papers, a significant improvement in radiomics methodologies has been demonstrated in the last year.
摘要：
背景：唾液腺成像的影像组学可以在不同的临床场景中支持临床决策，如肿瘤，放射性口干症和唾液腺炎。这篇综述旨在评估唾液腺成像的影像组学研究的方法学质量。材料与方法：进行了系统的检索，并使用影像组学质量评分（RQS）评估方法学质量。根据第一作者的专业角色（医学或非医学）进行亚组分析，进行期刊类型(放射学期刊或其他)和出版年份(2021年或之前)。计算RQS与患者人数的相关性。结果：纳入23篇文献（平均RQS11.34±3.68）。大多数研究充分记录了成像协议（87％），而未进行前瞻性验证和成本-效果分析.纳入的研究均未提供开源数据。发现根据出版年份的RQS有统计学上的显着差异（p=0.009），2021年发表的论文的RQS略高于较早的论文。根据期刊类型或第一作者的专业角色没有差异。发现总体RQS与患者人数之间存在中度关系。结论：影像组学在唾液腺成像中的应用正在增加。尽管其当前的临床适用性可能会受到论文质量不足的影响，在过去的一年中，已经证明了影像组学方法的显着改进。
