Is the word imagens the same in Brazilian and European Portuguese?

Yes.

The spelling, meaning, and grammatical category of "imagens" are identical in both Brazilian and Continental Portuguese. The only difference lies in pronunciation. In Brazilian Portuguese, the vowels are generally more open and clearly articulated, and the nasalization of the final "ns" is quite distinct. In Continental Portuguese, unstressed vowels are often more closed or reduced, meaning the "e" in the syllable "-gens" might be much shorter or almost whispered, and the rhythm of the word follows the more stress-timed nature of European Portuguese.
