急性坏死性胰腺炎59例CT分析

目的:通过对59例急性坏死性胰腺炎的螺旋CT表现分析,进一步探讨2mm薄层动态增强扫描诊断急性坏死性胰腺炎的价值。方法:59例经手术病理或CT复查确诊急性坏死性胰腺炎进行回顾性分析。全部病例采用螺旋CT平扫并薄层动态增强扫描。管电流140mAs,层厚2mm,床速1～2mm/s,螺距1/2。结果:CT平扫确定坏死灶17例(34%)。其中10例在薄层动态增强扫描时病灶数量增加,11例病灶范围扩大。全部59例经螺旋CT2mm薄层增强扫描都明确显示出坏死灶的范围、数量及胰腺周围情况。结论:螺旋CT2mm薄层增强扫描能明确坏死灶的部位、范围、程度及胰腺周围病理改变,对CT分级、病理变化、临床诊治及预后有重要意义。

Spiral CT Findings of Acute Necrosis Pancreatitis(add Analyze of 59 Cases )

Bstract: Objective Through analyze of 59 cases acute necrosis pancreatitis findings in spiral CT,To explore value of spiral CT 2mm thickness dynamic contrast enhanced scan in acute necrosis pancreatitis。 Methods 59 cases of acute necrosis pancreatitis were retrospectively analyzed and compared with laparotomy.All patients were examed with spiral CT plain scanning and thin thickness dynamic contrast enhanced scanning.In plain scanning with 8mm thickness and dynamic contrast enhanced scanning with 2mm thickness. Tube electric current 140mAs,Bed speed 1-2mm/s,1/2pitch .Results In spiral CT plain scanning define 17 cases,34%,10 cases among of them in thin thickness dynamic contrast enhanced scanning necrosis place quantity raise ,11 cases of them necrosis place range enlarged.All 59 cases of acute necrosis pancreatitis necrosis place quantity ,range and pancreatitis surrounding were showed obviously in thin thickness dynamic contrast enhanced scanning . Conclusion Spiral CT thin thickness dynamic contrast enhanced scanning can definite obviously necrosis places quantity ,range and pancreass surrounding in acute necrosis nancreatitis,have more important in CT classify,pathology change,clinical diagnosis and cure ,and prognosis.
