Overview
Key CT or MRI Findings in (Disease Name)
- MRI, although probably more sensitive that CT, is nonetheless still far from perfect with a sensitivity of only 67% 2. This is largely a result of the fact that as many as half involved nodes found histologically following surgery, being less than 3 mm in diameter 2.
- As discussed above, nodes have a tendency to become cystic. The cystic component will have near-fluid attenuation. The solid metastatic component will appear 2:
- General signal characteristics include:
- T1
- hypointense cf. muscle
- enhancement best seen with fat suppression
- T2: variable 2
- Hypointense: 34%
- Isointense: 45%
- Hyperintense: 21%
