Abstract
Purpose: to assess the role of Diffusion-weighted MRI in diagnosis of acute pancreatitis by measure the apparent diffusion coefficient (ADC) values detected by diffusion-weighted imaging (DWI) in acute pancreatitis and compare them with the control group
Methods and material: sixteen patients with acute pancreatitis and sixteen normal controls underwent DWI with b values (0,200 & 800). Apparent diffusion coefficient (ADC) maps are generated from DWI and ADC values were calculated for pancreas and compared the results between the two groups
Results: The mean pancreatic ADC in the AP group (1.15 × 10(-3) mm (2)/s ± 0.28) was significantly lower than in the normal group (1.6 × 10(-3) mm (2)/s ± 0.2). A threshold ADC value of 1.38 × 10-3 mm (2)/s yielded 81.25 %, specificity of 93.75 %, positive predictive value of 92.9 %, negative predictive value of 83.3 % and accuracy of 91.8%. Pancreatic ADCs are significantly lower in patients with AP than normal controls.
Conclusion: MR diffusion imaging could be an important supportive tool in diagnosis of acute pancreatitis
