Study Notes
Amyloidosis Imaging Features
- Amyloid deposits can be localized (amyloidoma) or widespread (diffuse).
- Amyloid deposits appear dark (hypovascular) on contrast-enhanced CT and MRI scans. Delayed enhancement can sometimes be seen.
- CT scans frequently show calcification, a strong indication of amyloid presence.
- MRI reveals amyloid deposits as appearing dark (hypointense) on both T1 and T2 weighted images.
