中文摘要:
      目的:探讨多层螺旋CT(MSCT)与MRI在急性胰腺炎诊断中的临床应用价值。方法:回顾性分析临床疑似急性胰腺炎66例患者的临床、MSCT、MRI资料,采用MSCT与MRI进行检查,将两种影像检查结果与病理结果进行比较得出结论。结果:66例临床疑似为急性胰腺炎患者,MSCT诊断急性胰腺炎为阳性43例,占65.15%(43/66);MSCT平扫主要表现为胰腺体积增大,密度均匀或不均匀,出血区为高密度灶,液化坏死为低密度灶,增强扫描胰腺呈均匀或不均匀明显强化,液化坏死区无强化。MRI诊断急性胰腺炎为阳性51例,占77.27%(51/66);MRI主要表现为胰腺体积肿大,胰腺及胰周积液呈T1低T2高信号。病理诊断急性胰腺炎结果为阳性52例,占78.79%(52/66)。MRI对急性胰腺炎诊断的敏感性、准确性(96.15%、95.45%)明显高于MSCT(75.00%、74.24%),差异有统计学意义(χ2=7.790、9.959,P<0.05)。MRI对急性胰腺炎诊断的特异性(92.86%)高于MSCT(71.43%),但差异无统计学意义(χ2=0.974、P=0.324)。结论:MRI对急性胰腺炎诊断的敏感性、特异性、准确性均高于MSCT,对于急性胰腺炎MSCT检查有禁忌证、需要多次复查的患者,MRI检查具有更大的优势。
英文摘要:
      Objective: To explore Multislice CT (MSCT) and MRI in the diagnosis of acute pancreatitis clinical application value. Methods: Clinically suspected acute pancreatitis were retrospectively analyzed clinical, MSCT and MRI data of 66 patients, using MSCT and MRI inspection, the two kinds of imaging results compared with the pathological results come to the conclusion. Methods: 66 patients with clinically suspected for acute pancreatitis, MSCT in the diagnosis of acute pancreatitis is positive 43 cases, accounting for 65.15% (43/66); MSCT scan mainly for pancreas volume increases, the density of the uniform or non-uniform, bleeding area for high density foci, liquefied necrotic for low density foci, enhanced scanning of pancreas in homogeneous or inhomogeneous obvious reinforcement, liquefied necrotic area without reinforcement. MRI in the diagnosis of acute pancreatitis is positive 53 cases, 77.27% (51/66); MRI mainly for pancreas swelling volume, pancreas and peripancreatic fluid has low T1 T2 signal. Results: the pathological diagnosis of acute pancreatitis is positive 52 cases, 78.79% (52/66). The sensitivity and accuracy of the MRI diagnosis of acute pancreatitis (96.15%, 95.45%) was obviously higher than MSCT (75.00%, 74.24%), the difference was statistically significant (χ2=7.790, 9.959, P<0.05). Specificity of MRI diagnosis of acute pancreatitis (92.86%) than MSCT (71.43%), but there was no statistically significant difference (χ2=0.974, P=0.974). Conclusion: MRI the sensitivity, specificity and accuracy of the diagnosis of acute pancreatitis were higher than MSCT, MSCT examination for acute pancreatitis patients with contraindications, need multiple reexamination, MRI has more advantages.
