Abstract

ObjectiveTo explore and analyze the relationship between the 1.5T MR imaging features and the diagnosis of parotid tumor patients and the comparison of pathological results.Methods70 patients with early parotid tumor from May 2016 to May 2019 were selected. All patients were examined with 1.5T MR in our hospital and confirmed by pathological diagnosis. Among them, 51 cases were benign tumors (benign tumor group) and 19 cases were malignant tumors (malignant tumor group). The MR and pathological results of benign and malignant tumors, the characteristics of MR imaging results of benign and malignant tumors (including location, shape, density, contour), the types of MR time signal curve and peak time of benign and malignant groups were analyzed and compared.ResultsThere was no significant difference between MR diagnosis of parotid tumors and pathological results (P>0.05); there was significant difference between MR imaging results of parotid benign and malignant tumors (P < 0.05), and there was significant difference between the location, shape, density, contour and other manifestations of benign and malignant tumors (P < 0.05). There was significant difference between the two groups in the dynamic characteristics of tumor MR (P < 0.05), and between the benign group in the persistent type and the clearance type(clearance rate≥0.3%), flat type rate was significantly higher than malignant group (P < 0.05), malignant group clearance rate (clearance rate < 0.3%) was significantly higher than benign group (P < 0.05), benign group peak time was significantly higher than the control group (P < 0.05), with statistical significance.Conclusion1.5T MR has a high diagnostic efficiency in the diagnosis of parotid tumor patients, and it has a great value in the differentiation of benign and malignant tumors, which is worthy of clinical promotion.
- parotid gland tumor,
- influence characteristics,
