Pancreatic carcinoma coexisting with chronic pancreatitis versus tumor-forming pancreatitis: Diagnostic utility of the time-signal intensity curve from dynamic contrast-enhanced MR imaging

Figure 2 Representative pancreatic TIC profiles in patients with pancreatic ductal carcinoma developed in a normal pancreas. A, B: Dynamic contrast-enhanced MRI images of the pancreas in a 59-year-old man with carcinoma of the head of the pancreas. The ROIs are placed at the pancreatic mass (No.2 ROI) and the non-tumorous pancreatic parenchyma both proximal (No.1 ROI) and distal (No.3 ROI) to the mass lesion; C: Pancreatic TICs obtained from the no.1 and no. 2 ROIs as in (A) demonstrate type-I and type-IV, respectively; D: Pancreatic TIC obtained from the No.3 ROI as in Figure 2B shows type-II.
