MRI scans: To see a tumor or AVM with MRI depends on many factors, including the size, shape, location, enhancement and secondary signs such as edema and changes in normal anatomy. A very small tumor in the right location can be easily seen, but even larger tumors cannot be seen until they change the anatomy of the rest of the brain or enhance. And very small tumors at times are not seen. Same for AVM.

No one: can stay completely still during an MRI. Movement artifact often masks very small findings. Some tyhings that can cause big problems are very very small and not on the "slices" of data imaged. If your symptoms are consistent with a tumor and all of the doctors treating you agree, then the real person overrules the imaging study.
