【摘要】：目的:使用双源CT双能量扫描,探讨正常肝脏、胰腺、脾脏的碘含量特征,建立正常肝脏、胰腺、脾脏的碘含量参考值。方法:对54例非器质性疾病患者行双源CT双能量双期增强扫描。使用Siemens Dual Energy-Liver VNC图像处理软件对动脉晚期、门静脉期0.7mm图像进行分析处理。测量肝脏、胰腺(胰头、胰体、胰尾)、脾脏及腹主动脉(腹腔干开口的上一层面)的含碘值,并计算标化含碘值(nIC)。结果:正常肝脏在动脉晚期和门脉期的nIC值分别为0.10±0.09和0.40±0.09;正常胰腺各部位在动脉晚期的nIC值分别为0.29±0.32(胰头)、0.29±0.31(胰体)和0.28±0.35(胰尾),在门脉期分别为0.49±0.21(胰头)、0.46±0.17(胰体)和0.46±0.16(胰尾);正常脾脏在门脉期的nIC值为0.02±0.05。不同年龄、不同性别组间正常肝脏、胰腺和脾脏nIC值的差异均无统计学意义(P0.05);胰腺不同部位nIC值的差异无统计学意义(P0.05);不同扫描期相肝脏nIC值的差异有统计学意义(P0.05)。结论:双源CT扫描可获得正常肝脏、胰腺、脾脏的碘含量,可为肝脏、胰腺及脾脏疾病的诊断提供参考。
[Abstract]:Objective: to study the characteristics of iodine content in normal liver, pancreas and spleen by dual-source CT dual-energy scanning, and to establish the reference value of iodine content in normal liver, pancreas and spleen. Methods: 54 patients with non-organic diseases were examined by dual-source CT dual-energy dual-phase enhancement. Siemens Dual Energy-Liver VNC image processing software was used to analyze and process 0.7mm images in late arterial and portal phase. The iodine content of liver, pancreas (head of pancreas, body of pancreas, caudate of pancreas, spleen and abdominal aorta) was measured, and the standardized iodine content was calculated. Results: the nIC values of normal liver were 0.10 卤0.09 and 0.40 卤0.09 in the late arterial phase and 0.40 卤0.09 in the portal phase, respectively, and the nIC values of the normal pancreas were 0.29 卤0.32 at the late arterial stage (0.29 卤0.31 (pancreatic body) and 0.28 卤0.35 (caudate of the pancreas), respectively, and 0.49 卤0.21 (0.46 卤0.17) (the pancreatic body) and 0.17 (the pancreatic body) in the portal phase, respectively. The nIC value of normal spleen in portal phase was 0.02 卤0.05. There was no significant difference in nIC value of normal liver, pancreas and spleen between different age and sex groups, but there was no significant difference in nIC value in different parts of pancreas (P 0.05), and there was significant difference in nIC value of liver in different scanning phase (P 0.05). Conclusion: Dual-source CT scan can obtain iodine content of normal liver, pancreas and spleen, and can provide reference for diagnosis of liver, pancreas and spleen diseases.
