摘要:
目的探究并分析1.5 T MR影像特征与腮腺肿瘤病人良恶性诊断的关系及病理结果。 方法选取2016年5月~2019年5月收治的早期腮腺肿瘤患者70例，所有患者均在我院进行1.5 T MR检查，并经病理诊断确诊。其中良性肿瘤51例（良性肿瘤组），恶性肿瘤19例（恶性肿瘤组）。分析并比较良恶性肿瘤的MR及病理结果、良恶性肿瘤MR影像结果特点（包括位置、形态、密度、轮廓）、良恶性组MR时间信号曲线类型及峰值时间。 结果MR诊断腮腺肿瘤结果与病理学结果差异无统计学意义（P>0.05）；腮腺良恶性肿瘤MR影像学结果比较，差异有统计学意义（P < 0.05），良恶性肿瘤在位置、形态、密度、轮廓等表现差异均具有统计学意义（P < 0.05）；两组肿瘤MR动态特点比较，差异具有统计学意义（P < 0.05），良性组持续型、廓清型（廓清率≥0.3%）、平坦型比率高于恶性组（P < 0.05），恶性组廓清型（廓清率 < 0.3%）比率高于良性组（P < 0.05），良性组峰值时间高于对照组，差异具有统计学意义（P < 0.05）。 结论1.5 T MR在腮腺肿瘤病人良恶性诊断中具有较高的诊断效能，对于良恶性肿瘤的鉴别具有较大的价值，值得临床推广。 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. -
