急性胰腺炎30例CT诊断分析

目的总结急性胰腺炎的CT诊断特点，进一步提高诊断水平。方法收集我院2011年1月至2013年2月经CT诊断的30例急性胰腺炎患者，所有患者均经实验室检查及腹腔穿刺证实，全部病例均采用东软CT—C3000螺旋CT机进行检查。结果本组30例患者均表现为胰腺局限性或弥漫性肿胀，其中急性坏死型3例，占10％，急性水肿型27例，占90％。较早的急性坏死性胰腺炎CT表现为：腹膜病变、肾周间隙模糊；急性坏死性胰腺炎CT表现：胰腺实质内密度较低，增强扫描无强化，多为囊样低密度区域，胰腺外形增大，且为弥漫性；急性单纯水肿型胰腺炎的CT表现：①肾周筋膜增厚，增强后均匀强化。②胰腺轮廓清晰或模糊，渗出者明显。③胰腺密度正常或轻度减低。④胰腺体积局部或弥漫性增大。结论CT可以作为诊断急性胰腺炎的重要依据，同时也是判断预防的重要检查手段。

CT diagnosis analysis of 30 cases of acute pancreatitis

Objective To summarize the CT characteristics of the acute pancreatitis, further to improve the diagnosis rate. Methods Thirty patients diagnosed by CT were collected from january 2011 to February 2013 in our hospital, all patients were confirmed by clinical laboratory, tests and abdominal puncture examination, all cases Neusoft CT-C3000 spiral CT machines were used for inspection. Results The group of 30 patienls showed the pancreas localized or diffuse swelling, three eases were acute necrotizing, accounting for 10.0%： and 27 cases were, acute edematous, accounting for 90.0%. Earlier acute necrotizing panereatitis CT findings were： peritoneal lesions, perirenal space fiazzy; CT findings of acute necrnlizing panereatitis were： the density of pancreatic parenchyma is low, enhanced scan showed no enhancement, mostly for ]uw-density region of the cystic pancreatic shape increase and diffuse; the a- cute isolaled edematous pancreatitis CT performance were： ①The perirenal fascia thickening, enhanced homogeneous enhancement. ②A clear oulline of the pancreas or fuzzy, oozing significantly. ③The density of the pancreas was norreal or slighlly reduced. ④Parlial or diffuse pancreatic volume increases. Conclusion CT can be used as an impurtant basis for the diagnosis of acute panereatitis, and also is tan important examination to determine prevention.
