【摘要】 目的 探讨64排螺旋CT对腹膜后节细胞神经瘤的诊断与鉴别诊断。方法 回顾性分析6例经手术病理证实的腹膜后节细胞神经瘤的64排螺旋CT表现,重点分析动脉期、静脉期及延迟期强化特点。结果 增强扫描动脉期瘤体实质部分渐进性轻微强化6例,瘤体内其他部位呈均匀略高于囊性密度。6例静脉期强化程度均较动脉期略强,较动脉期平均高6～10 HU。结论64排螺旋CT三期增强扫描及三维重建在腹膜后节细胞神经瘤诊断中有重要价值。更多还原

【Abstract】 Objective To explore the diagnosis and differential diagnosis of 64-slice spiral CT in retroperitoneal ganglioneuroma.Methods 64-slice spiral CT findings of retroperitoneal ganglioneuroma proved by operation and pathology were retrospectively analysed and focused on contrast-enhanced characteristics in arterial,venous and delayed phase.Results The solid parts of tumors in 6cases were enhanced slightly and gradually during arterial phase,the other regions of tumors were slight homogeneous dense compared with that of cyst.The tumors were enhanced obviously in venous phase than that in arterial phase,the average CT value was increased about 6～10 HU.Conclusion 64-slice spiral CT has important value in diagnosing retroperitoneal ganglioneuromas.更多还原
