【摘要】：目的：探讨急性胰腺炎(AP)并发肝脏损害肝脏密度降低的原因。方法：35例急性胰腺炎(AP)肝脏损害患者进行治疗前后CT.MRI影像学对比观察；MRI检查序列为T2WI脂肪抑制,T1WI同相位(in-phase); T1WI反相位(out-phase)。结果：35例急性胰腺炎(AP)肝脏损害患者肝脏CT值都有不同程度的降低,治疗后都有不同程度的恢复；MRI检查：35例患者肝脏T2WI脂肪抑制治疗前后均呈等信号；T1WI同相位35例均为稍高信号,治疗前后无明显变化；T1WI反相位：治疗前10例呈低信号,14例呈稍低信号,6例呈等信号,5例呈较高信号；治疗后7例呈高信号,18例呈稍高信号,5例呈等信号,2例呈低信号,3例呈稍低信号。患者治疗前后CT值t检验,t=-7.226,P0.01；治疗前后Out-phase像卡方检验,卡方值=26.890,P0.01；均有统计学意义。结论：急性胰腺炎肝脏损害肝脏密度降低的影像特征符合肝脏脂肪成分增加导致。
[Abstract]:Objective: to investigate the causes of hepatic density decrease in acute pancreatitis (AP) complicated with liver damage. Methods Thirty-five cases of acute pancreatitis (AP) with liver damage were examined by CT and MRI imaging before and after treatment. The sequence of MRI was T2WI fat suppression T1WI (in-phase), T1WI inverse phase (out-phase). Results the CT value of liver in 35 patients with acute pancreatitis (AP) was decreased in different degree, and the recovery of MRI in different degree was observed in 35 cases of acute pancreatitis (AP) before and after T2WI fat suppression treatment. Before and after treatment, 10 cases showed hypointensity in 14 cases with hypointensity in 6 cases, and 5 cases showed high signal intensity in 5 cases. After treatment, 7 cases showed hyperintense signal in 18 cases, slightly high signal intensity in 5 cases, isokinetic signal in 2 cases, low signal intensity in 3 cases, and slightly low signal intensity in 3 cases. Before and after treatment, the CT value of the patients was t test and the Out-phase chi-square test had statistical significance. Conclusion: the image features of liver density decrease in acute pancreatitis accord with the increase of hepatic fat content.
