Overview
MRI may be helpful in the diagnosis of papillary thyroid cancer. MRI may also be performed to detect metastases of papillary thyroid cancer to brain and bones.
Key CT or MRI Findings in Papillary thyroid cancer
- 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%
