目的:探讨并分析CT联合MRI在腹部神经节细胞瘤诊断中的应用价值。方法:回顾性分析2016年1月-2017年6月期间我院收治的经病理证实的28例腹部神经节细胞瘤患者,均接受CT与MRI诊断,观察分析CT与MRI联合诊断腹部神经节细胞瘤的应用效果。结果:CT诊断,20例确诊,8例漏诊/误诊,符合率为71.4%(20/28),MRI诊断,22例确诊,6例漏诊/误诊,符合率为78.5%(22/28),CT联合MRI诊断,27例确诊,1例漏诊,符合率为96.4%(27/28),经对比,差异显著,具备统计学意义(P<0.05)。CT诊断,17例呈均匀低密度,11例呈不均匀低密度,密度平均值为(27.0±3.9)HU,11例轻度强化(39.2%),12例中度强化(42.9%),5例显著强化(17.9%)。MRI诊断,19例T1WI低信号,9例T1WI稍低信号,21例T2WI稍高信号,7例T2WI较高信号。17例呈条絮状、云雾状强化,11例呈斑点状、不均匀条状强化。结论:腹部神经节细胞瘤,联合CT与MRI诊断,准确率高,值得推广。
Objective: To explore and analyze the value of CT combined with MRI in the diagnosis of abdominal ganglioneuroma. Methods: A retrospective analysis of 28 patients with pathologically confirmed abdominal ganglioneuroma admitted from January 2016 to June 2017 in our hospital were performed CT and MRI. CT and MRI were used to diagnose abdominal ganglion cells Tumor application effect. Results: CT diagnosis, 20 cases were diagnosed, 8 cases missed or misdiagnosed, the coincidence rate was 71.4% (20/28), MRI diagnosis, 22 cases diagnosed and 6 cases misdiagnosis / misdiagnosis, the coincidence rate was 78.5% (22/28) CT combined with MRI diagnosis, 27 cases were diagnosed, 1 case missed diagnosis, the coincidence rate was 96.4% (27/28), by contrast, the difference was statistically significant (P <0.05). CT was diagnosed in 17 patients with uniform low density, 11 with uneven low density, average density of (27.0 ± 3.9) HU, 11 mild enhancement (39.2%), 12 moderate enhancement Cases were significantly enhanced (17.9%). MRI diagnosis, 19 cases of low signal T1WI, 9 cases of T1WI slightly lower signal, 21 cases of T2WI slightly higher signal, 7 cases of T2WI higher signal. 17 cases were flocculent, cloud-like enhancement, 11 cases were spotty, uneven strip enhancement. CONCLUSION: Abdominal ganglioneuroma, combined with CT and MRI diagnosis, has high accuracy and is worth popularizing.
