Common cystic pancreatic neoplasms: A comprehensive magnetic resonance imaging-based review of typical and atypical imaging features

Figure 13  Typical magnetic resonance imaging appearance of mucinous cystic neoplasm. A and B: Coronal and axial T2-weighted images show a well-defined unilocular cystic lesion in the pancreatic tail, with homogeneous high signal intensity and smooth margins; C: Axial T1-weighted image demonstrates homogeneous low signal intensity of the cystic content, without intrinsic T1 hyperintensity suggestive of hemorrhagic or proteinaceous material; D: Diffusion weighted imaging (b = 1000 second/mm²) shows no diffusion restriction within the lesion; E: Post-contrast T1-weighted image shows no enhancing mural nodules and no internal solid components.
