Figure 2From: The primary study of low-dose pancreas perfusion by 640- slice helical CT: a whole-organ perfusionROI, time density curve and blood flow image of normal pancreas. A1(B1,C1) shows the ROI of normal pancreas without any pancreatic disease in whole sequence (odd number sequence,even number group). A2 (B2,C2) represents the corresponding time density curve; A3 (B3,C3) represents the blood flow image.Back to article page
