They used the MRI data to look at the 'connectivity', or strength of brain networks, in the basal ganglia – part of the brain known to be involved in Parkinson's disease. Non-contrast also provides greater images of blood vessel activity, detecting aneurysms and blocked blood vessels. 4 Answers. an MRI of the head with and without contrast shows the brain and sinuses, and is useful for outlining growths/tumors. In many cases a contrast substance such as gadolinium or iodine is administered to the patient, typically to make the blood vessels, intestines or another area of the body appear opaque during the MRI procedure.
