Craniopharyngioma protocol

So, we discovered that my younger brother (12 yo) had a lesion in the brain, we don’t know if it’s craniopharyngioma or a dermoid cyst, but i lean more on craniopharyngioma. due to rush and shock we didn’t find time to check for every single radiology section and report. But now we calmed down. So, we have transverse ct, and t1, t2, flair, dwi mri, transverse and sagittal. We don’t have the coronal. So, about the ct, do we repeat it again looking for better quality and diagnosis? Or ct is not the differential step in the process? I prioritize his wellbeing and comfort. Is ct that important or the consultant will rely more on the mri?
