摘　　要：目的探讨肝脏真菌感染在动态CT增强扫描中的影像特征表现和临床应用价值。方法 8例经临床证实的肝脏真菌感染的患者,采用MSCT机行动态增强扫描,分析肝脏真菌感染在动态CT增强扫描中的影像征象。结果 8例肝脏真菌感染的CT平扫多数为多发的圆形低密度灶,边界不清,部分弥漫性小结节难以显示。动脉期CT图像示病灶环形明显强化,中心强化少或无强化,周围有异常灌注;门静脉期强化的病灶缩小和数目减少;延迟期大部分病灶仍显示为环状强化,弥漫性的小结节显示境界更清楚。某些大病灶动脉期边缘仅轻度强化或无明显强化,门静脉期和延迟期强化仍不明显。结论动态CT增强能很好地反映肝脏真菌感染的特征,动脉期和延迟扫描比门静脉期扫描更易于发现病灶,该方法作为疾病的诊断和疗效评价非常有价值。[Objective] To investigate the liver fungal infection in dynamic enhanced CT imaging featuresand its clinical value. [Methods] 8 patients with clinically confirmed by fungal liver infections were scannedby MSCT dynamic contrast enhanced. CT imaging features of dynamic enhanced scanning in hepatic fungalinfection were analyzed. [Results] Most CT non-contrast enhanced scan images in 8 cases with hepatic fungal infection performance circular low density lesion and unclear boundary. Some diffuse small nodules dis-played difficultly. CT images in Tarterial-phase scan showed significantly ring enhancement, Center forstrengthening less or no enhancement and abnormal perfusion around. The tumor size and the number reducedin portal venous phase enhanced. Most lesions were still showed ring enhancement in delay phase. Diffusesmall nodules displayed more clearly the realm. Some of the bigger lesions enhanced light or no enhancement.In arterial phase scan. It isn＇t still no enhancement in portal venous and delayed phase. [Conclusion] Dynamic enhanced CT can well reflect the characteristics of fungal infection of the liver. It is easier to detectlesions in arterial and delay phase scan than vein phase. This method is very valuable as the diagnosis andtreatment of disease assessment.
