MRI & CT SCAN RESULTS; help needed.

I went to the vanderbilt ER not too long ago,
(NOTE:i was in an recent car wreck,and fractured my C7,Pelvis,tailbone,tiny cut in spleen,bruised kidney,tiny tear in liver.)

& had an mri done,a vascular specialist reviewed my mri scan done on my neck & brain and had said there was an suspicious area & that it could be artery injury(on back of neck),He said he was going to have a neurologist examine & get his input. the neurologist reviewed it & suggested something to do with the blood vessel in area.Then he ordered an CT scan at the same area & brain.The CT scan had shown that my arteries in back of neck were fine & he noted that there was an "tiny" amount of blood in brain.So then an professor comes in & diagnosed me with vertigo & thats all.

in my understanding the MRI is way far accurate as far as arteries go then an CT scan.They basically just went with the CT scan results.None of this makes sense to me.
Or am i totally wrong?Why is it that with the MRI,there was an suspicious area & then when an CT scan was done it was dismissed?

SYMPTOMS:i noticed myself during several experiments,sleeping on different sides & writing down what i experience.When i sleep on my left side & wake up,theres somewhat almost no vertigo present nor the problem of balance (which usually i will lean to the right side unintentionally).Then i had slept on my right side & noticed the moment i wake up,vertigo (room spinning) & imbalance(leaning to right side).And also,when i turn my neck to left no symptoms occur but the moment i turn my neck to right,i experience vertigo.

NOTE:the doctor had said that me having a small amount of blood in brain,would of not caused any of those symptoms,is that correct?

First, it sounds like a mess!   Are you still seeing these physicians or were they just involved in the ER?  I would be getting second opinions; another neurologist and vascular
specialist opinions.

Secondly, MRI imaging is superior to a CT .  I would go with the findings of the MRI and CT.  CT picked up the small amount of blood in the brain, but not the artery problem.
The MRI picked up the artery issue.  This happens.  I don't know why the physician would dismiss the findings of the MRI.    

Thirdly, if you have a possible artery injury, as the MRI suggests, that could explain the vertigo symptoms.  The small amount of blood in the brain does not help matters, but I don't think it is as significant as having an injuried artery in the back of the neck.  

Keep us posted.
