The incidence of renal mass detection has increased during recent decades, with an increased diagnosis of small renal masses, and a final benign diagnosis in some cases. To avoid unnecessary surgeries, there is an increasing interest in using radiomics tools to predict histological results, using radiological features. We performed a narrative review to evaluate the use of radiomics in renal mass characterization. Conventional images, such as computed tomography (CT) and magnetic resonance (MR), are the most common diagnostic tools in renal mass characterization. Distinguishing between benign and malignant tumors in small renal masses can be challenging using conventional methods. To improve subjective evaluation, the interest in using radiomics to obtain quantitative parameters from medical images has increased. Several studies have assessed this novel tool for renal mass characterization, comparing its ability to distinguish benign to malign tumors, the results in differentiating renal cell carcinoma subtypes, or the correlation with prognostic features, with other methods. In several studies, radiomic tools have shown a good accuracy in characterizing renal mass lesions. However, due to the heterogeneity in the radiomic model building, prospective and external validated studies are needed.
近几十年来，肾脏肿块的检出率有所上升，小肾脏肿块的诊断增多，且部分病例最终诊断为良性。为避免不必要的手术，利用放射组学工具通过放射学特征预测组织学结果的兴趣日益浓厚。我们进行了一项叙述性综述，以评估放射组学在肾脏肿块特征描述中的应用。传统影像，如计算机断层扫描（CT）和磁共振成像（MR），是肾脏肿块特征描述中最常用的诊断工具。使用传统方法区分小肾脏肿块中的良性和恶性肿瘤可能具有挑战性。为了改善主观评估，利用放射组学从医学影像中获取定量参数的兴趣有所增加。多项研究评估了这种用于肾脏肿块特征描述的新工具，将其区分良性与恶性肿瘤的能力、区分肾细胞癌亚型的结果或与预后特征的相关性与其他方法进行了比较。在多项研究中，放射组学工具在描述肾脏肿块病变方面显示出良好的准确性。然而，由于放射组学模型构建的异质性，需要进行前瞻性和外部验证研究。
