[|Human|] my oral surgeon wants me to get a ct scan with contrast dye for a possible palate tumor. I have an imperceptible bump on the palate, and it hurts at night, but gets better in the day. I am afraid of this test with the dye, and wanted to ask if I would have a better chance of getting an accurate diagnosis with an mri, or a pet scan.
[|AI|]  Thanks for your query, I have gone through your query. The palatal tumors can e better assessed by the contrast CT, Because it gives the exact extent of the lesion, the involved area takes up the dye. The MRI is indicated for soft tissue lesion. It won't give a picture of bone involvement. If there is a bony involvement by the tumor, it will not be displayed in MRI, so CT is the better option. Contrast CT is indicated to find out any spread of tumors(metastasis) and to find out the extent of the lesion. You can go for either CT or PET CT Rather than MRI. Nothing to worry about dye, you can get it checked for any allergies before administering the dye. I hope my answer will help you, take care.
