Overview

On Abdominal MRI, pancreatic cancer appears as hypointense with slower enhancement than normal pancreas

MRI

Signal characteristics include:

• T1: hypo intense c.f. normal pancreas 5
• T1 FS: hypo intense c.f. normal pancreas 5
• T1 + C (Gd): slower enhancement than normal pancreas, therefore dynamic injection with arterial phase imaging with fat saturation is ideal
• T2/FLAIR: variable (therefore not very useful) depending on the amount of reactive desmoplastic reaction 1,5
