| 目的 评价CT增强扫描在腮腺病变诊断中的价值。方法 通过回顾性分析62例经手术病理证实的腮腺病变的增强CT表现,并与病理诊断进行对照分析。结果 33例良性病变中,25例良性肿瘤表现为密度均匀,边界清楚;5例表现为密度不均匀,边界清楚或不清楚;3例炎症则密度不均匀,边界不清楚。29例恶性肿瘤中,26例为密度不均匀,边界不清楚,3例密度较均匀,边界清楚。结论 CT增强扫描对腮腺病变的定性诊断,特别是良恶性肿瘤方面具有较高的价值。 |

| Objective To study the value of the contrast CT in the diagnosis of parotid diseases. Methods The contrast CT findings of 62 cases parotid diseases proved by operation and pathology were retrospectively analyzed. Results The final diagnoses were : benign lesions (33) and malignant tumors (29). Among the 33 benign lesions, there were 30 benign tumors, twenty-five of 30 benign tumors were well-defined, homogenous in density, 5 of 30 benign tumors were inhomogeneous, but with well-defined or poor-defined. Twenty-six of 29 malignant tumors were both poor-defined and homogeneous, and 3 of 29 malignant tumors were well-defined and homogeneous. Conclusion The contrast CT scan has significant value in localizing and qualifying diagnosis, especially in differentiating diagnosis between benign and malignant tumors of parotid gland. |
