Multimodal magnetic resonance imaging for the diagnosis of parotid gland malignancies: systematic review and meta-analysis.

Background: To systematically evaluate the qualitative diagnostic value of multimodal magnetic resonance imaging (MRI) for parotid gland tumors. However, there is still a lot of controversy in this area, and the results of different studies are not consistent. Therefore, it is necessary to use meta method to analyze the significance of multimodal MRI in the diagnosis of parotid gland tumors.

Systematic review and meta-analysis of imaging differential diagnosis of benign and malignant ovarian tumors.

Background: With the increasing incidence of gynecological ovarian tumors, the differential diagnosis of benign and malignant ovarian tumors is of great significance for subsequent treatment. Currently, ovarian examinations commonly use computed tomography (CT) or magnetic resonance imaging (MRI). This study sought to compare the value of CT and MRI in differentiating between benign and malignant ovarian tumors.
