目的:研究磁共振扩散加权成像在轻症急性胰腺炎诊断中的诊断应用价值。方法选取55例轻症急性胰腺炎患者的临床资料,回顾分析所有患者的临床数据资料,同时选取同期收治的55例正常体检者进行对照,所有研究对象均接受磁共振扩散加权成像(DWI)常规磁共振(MR)检查,均于48 h内完成检查,对胰腺表现弥散系数(ADC)值进行测量,比较轻症急性胰腺炎与正常体检者在ADC上的差异。结果:(1)在55例急性胰腺炎患者中,通过常规MRI扫描,无明显异常现象患者6例,有明显异常现象患者49例。(2)对于轻症急性胰腺炎患者而言,有39例表现为弥漫均匀性高信号,9例表现为不均匀性高信号,7例表现为中等信号。(3)轻症急性胰腺炎的ADC值明显低于正常体检者,两组对比,差异有统计学意义(P<0.05)。结论采用DWI检测,可将急性胰腺炎患者的病灶范围反映出来,同时与测量的ADC值相结合,有利于尽早确诊患者病情,提高疾病诊断准确率。
Objective: To study the value of MR diffusion weighted imaging in the diagnosis of mild acute pancreatitis. Methods The clinical data of 55 patients with mild acute pancreatitis were retrospectively analyzed. The clinical data of all patients were retrospectively analyzed. At the same time, 55 normal subjects were enrolled in the study. All subjects underwent conventional diffusion-weighted imaging (DWI) Magnetic resonance (MR) examination was completed within 48 h to examine the performance of the pancreatic diffusion coefficient (ADC) values were measured to compare the severity of mild pancreatitis and normal subjects were ADC differences. Results: (1) Of the 55 patients with acute pancreatitis, 6 patients showed no obvious abnormalities and 49 patients had obvious abnormalities by routine MRI scan. (2) For patients with mild acute pancreatitis, 39 patients showed high signal of diffuse homogeneity, 9 patients showed high signal of inhomogeneity and 7 patients showed moderate signal. (3) The ADC value of mild acute pancreatitis was significantly lower than that of normal subjects, the difference was statistically significant (P <0.05). Conclusions DWI can reflect the extent of the lesion in patients with acute pancreatitis and at the same time, it can be used to diagnose the patient’s condition as soon as possible and improve the diagnostic accuracy of the disease.
