中文摘要:
      目的 探讨18F-FDG PET/CT偶然发现的上颌骨放射性浓聚灶的影像特点及临床意义。方法 回顾性分析45例PET/CT发现上颌骨牙根以外部位放射性浓聚患者的临床及影像学资料。观察上颌骨放射性浓聚灶的数目、部位、最大标准化摄取值(SUVmax)、大小、形态、密度等特点及随访变化。应用IBM SPSS软件分析病灶SUVmax与最大径、患者年龄的关系,以及随访SUVmax有无变化。结果 45例患者发现上颌骨浓聚灶49个,3个位于体部,46个位于额突,其中40个位于额突基底部,6个位于前上部。所有病变均呈磨玻璃密度,其中15个密度均匀,34个密度不均,病变内部见更低密度影。病变平均SUVmax 2.64±1.07,平均最大径(0.63±0.20)cm。病变SUVmax与最大径呈正相关,与患者年龄呈负相关。12例复查PET/CT,病变SUVmax变化无统计学差异,大小、密度等形态特征均无变化。结论 上颌骨偶发PET/CT放射性浓聚灶大多位于额突基底部,呈磨玻璃密度,倾向良性病变。
英文摘要:
      Objective To investigate the imaging features and clinical value of maxillary hot lesions accidentally detected on 18F-FDG PET/CT imaging.Methods Forty-five patients with increased uptake on the maxillary except periodontal region on PET/CT were retrospectively analyzed. The clinical and imaging features including number, location, SUVmax (maximal standard uptake value), size, shape and density were evaluated. IBM SPSS software was adopted to analyze the correlation of SUVmax with maximal diameter and patients' ages, as well as the difference of SUVmax between initial and follow-up scans.Results Forty-nine lesions were detected. Three lesions were located on the maxillary body, 46 on frontal process, 40 of which were at the base and 6 anterosuperior. All lesions showed ground-glass density, 15 of which were homogeneous and 34 heterogeneous. The mean SUVmax was 2.64±1.07 and maximal diameter were (0.63±0.20)cm. The SUVmax of lesions had positive correlation with maximal diameter, negative correlation with the age. All the lesions showed stable SUVmax and morphological features including density, size on follow-up PET/CT in 12 patients.Conclusion Most maxillary hypermetabolic lesions fortuitously detected on PET/CT are located at the base of frontal process, with ground glass density and probably benign clinical behavior.
