Hello, Haddadi Saïd.

Computed tomography examination demonstrate an accuracy of 83.3%, with sensitivity and specificity of 81.4% and 43%. Magnetic resonance imaging show diagnostic accuracy, sensitivity and specificity in pancreatic cancer of 89,1%, 89,5% and 63,4% respectively. However, using a combination of contrast-enhancement EUS and elastography, the diagnostic accuracy reaches 93,7%, with a specificity of 90,3% and sensitivity of 97,5%. So, EUS is the most effective technique in the diagnosis and staging of pancreatic cancer.

Hello, Sir Haddadi

EUS is the most effective technique used in the diagnosis of pancreatic cancer, the present study demonstrating an accuracy of 92.7%.

But if we talk just about MRI and CT, then Computed Tomography (CT) is more accurate for measuring the dimension of pancreatic adenocarcinoma.

I agree, EUS is the way to go. However, if you have limited access to EUS or need cross sectional information regarding vessels etc. both CT and MRI can serve as good adjuncts for planning.
