That is a CT scan.
That is not a functional MRI.
Now..would you like to expound for us what you see in the images you posted?
Your post lacks the ‘segmental number’ for each picture hence you may be deceiving readers with a segment on the left which shows more of the ventricle than the one on the right ... which can vary greatly depending upon the ‘verticle segment’ being displayed. But then you already knew that and went ahead with your ploy anyway.
