Findings on MRI suggestive of mucinous cystadenocarcinoma include lower signal intensity for loculi with watery mucin on T1-weighted images.

• T1

• The signal intensity of mucin on T1-weighted images varies depending on the degree of mucin concentration.
• On T1-weighted images, loculi with watery mucin have a lower signal intensity than loculi with thicker mucin.^[1]

• T2

• On T2-weighted images, the corresponding signal intensities are flipped, so that loculi with watery mucin have high signal intensity and loculi with thicker mucin appear slightly hypointense.
