Overview
Abdominal MRI is helpful in the diagnosis of pseudomyxoma peritonei. On abdominal MRI, pseudomyxoma peritonei is characterized by a mass which is hypointense on T1-weighted MRI and hyperintense on T2-weighted MRI.[1]
MRI
Helical CT is currently the best imaging technique in patients with pseudomyxoma peritonei. However, the limited contrast range of CT makes it difficult to distinguish mucin, ascites, and solid peritoneal tumor, MRI is more sensitive at identifying whether the mucocele is mucin or ascitic fluid.
