目的 探讨咽旁隙肿瘤的MRI表现特点及其临床诊断价值。方法 对 2 9例经手术病理证实的咽旁隙肿瘤的MRI征象进行分析 ,并与手术和病理结果相比较。结果 MRI对咽旁隙肿瘤定位和定性准确 ;不同组织来源的肿瘤与周围组织的关系在MRI特征上有不同 ;良性肿瘤界限清楚 ,信号分布均匀 ,T1WI主要表现为中等信号 ;恶性肿瘤信号分布不均匀 ,T1WI表现为低中信号。结论 本研究结果证实 ,MRI在诊断咽旁隙肿瘤中有其自身的特点 ,可作为临床重要诊断手段
Objective To investigate the MRI features and clinical diagnostic value of pharyngeal parapharyngeal tumors. Methods MRI findings of 29 parapharyngeal tumors confirmed by surgery and pathology were analyzed and compared with the results of surgery and pathology. Results MRI showed that the tumor located in the parapharyngeal space was qualitatively and accurately located. The relationship between the tissues from different tissues and the surrounding tissues was different according to the features of MRI. The benign tumor was well defined and the signal was evenly distributed. The T1WI mainly showed moderate signal. The distribution of malignant tumor signal was not Uniform, T1WI performance for the low signal. Conclusion The results of this study confirm that MRI has its own characteristics in the diagnosis of parapharyngeal space tumor and can be used as an important clinical diagnostic tool
