A member asked:
Can ct scan without contrast show any brain tumors?
7 doctors weighed in across 2 answers
Yes: A ct scan will show brain tumors if they are large enough, have calcium or blood in them, or are causing swelling. On some occasions, contrast is necessary to see other types of tumors.

Sometimes: Brain swelling, hemorrhage and mass effect can be noted on a head ct without contrast. Also, some tumors have calcification a which can be seen in a head ct. Smaller and lower grade tumors can sometimes be missed on a head ct without contrast.
