【摘要】 目的探讨多层螺旋CT增强扫描及多平面重组(MPR)在腭部恶性肿瘤诊断中的价值。资料与方法回顾性分析经病理证实的12例腭部恶性肿瘤患者的临床及CT资料。12例均行CT平扫及增强轴位扫描,并将获得的数据进行MPR。结果腭部肿块8例,其中硬腭2例,软腭4例,软、硬腭交界区2例;局部软组织增厚4例。腭骨骨质破坏4例;周围组织结构受累8例;头颈部淋巴结转移6例。CT增强扫描,病灶表现为轻度至显著、均匀或不均匀强化。MPR能清晰显示肿块与软腭、硬腭及周围咽腔等结构的大体解剖关系和肿块累及范围。结论CT增强扫描对判断腭部肿瘤的性质、累及范围及判断有无颈部淋巴结转移有重要价值,MPR能多平面地显示病灶与周围组织结构的大体解剖关系。更多还原

【Abstract】 Objective To evaluate diagnostic value of contrast CT and multiplanar reconstruction(MPR)technique in the application of palate tumor.Materials and Methods Clinical data and CT findings of 12 cases with palate malignant tumors proved by pathological results were analyzed retrospectively.All of 12 patients received plain and contrast CT scanning,multiplanar reconstruction(MPR)was done using CT data.Results 8 cases of palatal mass(2/8 in hard palate,4/8 in soft palate,2/8 in borderline of hard and soft palate)were found.Local soft tissues were thickened in 4 cases.We also found destruction of bone in 4 cases and surrounding tissue involved in 8 cases.Enlarged lymphoid node of head and neck were found in 6 cases.Lesions were presented mild or obviously homogeneous or inhomogeneous enhancement on contrast CT.MPR could clearly showed the gross anatomical relationship of mass,palate and pharyngeal cavity and invasion extent.Conclusion Contrast CT scanning has significant value in evaluating benign or malignant and range of palate tumors,and also enlarged lymphoid node in the head and neck.MPR technique can clearly show gross anatomical relationship of lesion and its surrounding structures.更多还原
