Higher volume growth rate is associated with development of worrisome features in patients with branch duct-intraductal papillary mucinous neoplasms

Figure 2 Contrast-enhanced computed tomography images (Brilliance iCT, Philips Medical Systems) of intraductal papillary mucinous neoplasms of the pancreatic head in the three planes of space. A: Axial view; B: Coronal view; and C: Sagittal view. The arrows indicate the location of the cyst.

Figure 3 Non-contrast-enhanced magnetic resonance images of intraductal papillary mucinous neoplasms. A: T2-weighted Turbo Spin Echo (TSE) axial image; B: T2-weighted TSE coronal image; C: T2-weighted TSE fat-sat axial image; and D: T2-weighted TSE volume (3D) TSE fat-sat sequences (with MIP reconstructions). The arrows indicate the location of the cyst.

The volume of the entire cyst was determined by manually drawing a region of interest along the edge of the neoplasm on each consecutive slice covering the whole lesion.
