Overview

CT scan can be done to assess for amyloid deposition in particular organs. It can also be done to rule out other causes of organ dysfunction. However, MRI is more sensitive than CT in the diagnosis of amyloidosis.

CT scan

In hepatic amyloidosis, CT scan findings may include:

In renal amyloidosis, CT scan findings may include:

In cardiac amyloidosis, CT scan findings may include[1]:
