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

Figure 6 Typical magnetic resonance imaging appearance of serous cystic neoplasm. A: Magnetic resonance cholangiopancreatography maximum intensity projection reconstruction shows a large microcystic lesion in the pancreatic tail; B and C: Coronal and axial single-shot T2-weighted images demonstrate a markedly hyperintense microcystic mass with thin septa converging toward a central scar; D and E: Pre-contrast and post-contrast T1-weighted images show a hypointense lesion with delayed enhancement of the central scar; F: Non-contrast computed tomography better depictes central scar calcification (arrow); G and H: Diffusion weighted imaging (b = 1000 second/mm²) shows mild hyperintensity on high b values due to T2 shine-through, as confirmed on apparent diffusion coefficient (ADC) map, which presents hyperintense signal, indicating absence of true restriction, and high ADC value (ADC = 3.2 × 10^-3 mm²/second).
