  • Figure 1
    CT
     

    Axial unenhanced CT scan image shows a calcified nodule in the pancreatic tail.

     
    Area of Interest: Pancreas; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Metastases;

    Axial CT scan image after contrast administration (arterial phase) shows the nodule in the pancreatic tail with a thin hypodense halo.

     
    Area of Interest: Pancreas; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Metastases;
