A member asked:
Mri contrast vs non contrast whats the big difference if any? misdiagnoses common with non contrast particularly in arachnoid cysts? are things missed in non contrast?

Yes it often helps: Contrast studies can definitely improve detection of subtle findings. Some tumors or other abnormalities can be difficult to differentiate from adjacent tissue, but do show marked enhancement with contrast due to disturbance of what is called the blood/brain barrier.

Level of resolution : Yes, contrast helps but so does using different software programs. Little is missed under these technologies
