目的：分析副脾CT误诊原因，通过CT量化分析，提高对副脾的诊断率，减少误诊。方法：回顾性分析13例经手术病理或临床随访证实的副脾患者的病例资料。所有患者均行CT三期动态增强检查，分别测量各期副脾及主脾的CT值。结果：13例副脾平均CT值动脉期85．3 HU，静脉期105．2 HU，延迟期70．7 HU。正常主脾平均 CT 值动脉期103．8 HU，静脉期117．3 HU，延迟期81．7 HU。通过量化分析：副脾各期CT值均比主脾略低，但是其三期动态增强，CT值动态变化形态与主脾一致，即动脉期明显强化，静脉期进一步强化，CT 值进一步增高，延迟期后强化程度减低。结论：副脾有典型的CT表现，通过CT量化分析，可提高对副脾的诊断，减少临床不必要的手术。
目的：分析副脾CT誤診原因，通過CT量化分析，提高對副脾的診斷率，減少誤診。方法：迴顧性分析13例經手術病理或臨床隨訪證實的副脾患者的病例資料。所有患者均行CT三期動態增彊檢查，分彆測量各期副脾及主脾的CT值。結果：13例副脾平均CT值動脈期85．3 HU，靜脈期105．2 HU，延遲期70．7 HU。正常主脾平均 CT 值動脈期103．8 HU，靜脈期117．3 HU，延遲期81．7 HU。通過量化分析：副脾各期CT值均比主脾略低，但是其三期動態增彊，CT值動態變化形態與主脾一緻，即動脈期明顯彊化，靜脈期進一步彊化，CT 值進一步增高，延遲期後彊化程度減低。結論：副脾有典型的CT錶現，通過CT量化分析，可提高對副脾的診斷，減少臨床不必要的手術。

Objective:To analyze the causes of misdiagnosis of accessory spleen and to improve the diagnosis of acces-sory spleen by CT quantitative analysis in order to reduce its misdiagnosing.Methods:A retrospective study on 13 patients with accessory spleen confirmed by pathology after operation or clinical follow-ups was conducted.All patients were per-formed three-phase dynamic contrast-enhanced CT scan.CT values of both accessory and main spleens in each phase were measured and recorded respectively for statistic analysis.Results:The average CT values for 13 accessory spleens were 85.3HU in arterial phase,105.2HU in vemous phase and 70.7HU indelayed phase.The average CT value for primary spleens were 103.8HU in arterial phase,117.3HU in venous phase and 81.7HU in delayed phase.Quantitative analysis re-sults showed that CT values for accessory spleens in each phase were slightly lower than those for primary spleens,however their dynamic changes of CT value were consistent with the main spleen,which showed an apparent CT value enhancement in the arterial phase,a further enhancement in the venous phase,and a reduced enhancement in the delayed phase.Conclu-sion:Accessory spleen has typical CT findings with the same dynamic enhancement pattern of main spleen.With the help of CT quantitative analysis,it is possible to improve the diagnosis of accessory spleen and reduce unnecessary surgeries.
