摘　　要：腮腺肿瘤病理类型较多,不同类型肿瘤的影像表现上具有相似性。常规MRI通常很难对肿瘤类型进行区分。近几年来MRI新技术越来越多地应用于腮腺肿瘤的诊断,如扩散加权成像、动脉自旋标记成像、磁敏感加权成像以及酰胺质子转移加权成像等,同时腮腺肿瘤影像组学研究也逐步开展。这些新技术、新研究方法不仅提高了肿瘤显示的敏感度,还可以定量分析肿瘤的血流灌注、组织代谢等情况,以及提取肿瘤的影像学特征建立模型,为腮腺肿瘤的诊断提供更精准的信息。本文就以上MRI新技术及影像组学在腮腺肿瘤中的应用进展进行综述,以提高对其在腮腺肿瘤综合评估中的价值的认识。The pathological types of parotid gland tumors are diverse and the differential diagnosis of parotid gland tumors is difficult.The images of different types of parotid gland tumors are similar sometimes. Conventional MR imaging is often difficult to distinguish the tumor types. In recent years, a series of new magnetic resonance technologies, such as diffusion-weighted imaging, arterial spin labeling, susceptibility-weighted imaging, amide proton transfer weighted imaging has been developed rapidly and radiomics has been applied to parotid gland tumors. These new technologies can not only improve the sensitivity in discovering tumors but analyze the blood perfusion and tissue metabolism of tumors quantitatively. To extract the imaging features of tumors and establish models, it can provide more accurate supplementary information for the diagnosis of parotid tumors. This paper has reviewed the progress of MRI technology and applications of radiomics in parotid gland tumors to improve the comprehensive assessment of parotid gland tumors.
