The research progress of CT and MRI in the submandibular gland lesions

The submandibular gland is the second largest salivary gland after the parotid gland, and the adjacent anatomical structure are complex and the disease entities are diverse. Imaging examination is an important auxiliary examination method, CT and MRI can be not only used to provide detailed anatomical information of the lesion, but also to effectively evaluate the nature of the lesion. New technologies such as CT and MR perfusion Imaging, dual energy CT, DWI and its derived sequences, and intravoxel incoherent motion (IVIM) provide more information on differentiating benign from malignant tumors and tumor from infectious diseases. In this article, we reviewed the research progress of CT and MRI in the salivary gland lesions, to explore the possibility of applying new CT and MRI imaging techniques in the evaluation of submandibular gland.
