A member asked:
If a person had a normal with and without contrast 1.5 tesla mra, should he do 3.0 tesla mra to be sur that 1 to 2 mm cerebral aneurysm was not mised?
A doctor has provided 1 answer
Not necessarily: MRA's ability to detect a 1-2 mm aneurysm depends on contrast vs. TOF technique, number of phase-encoded steps, and acquisition parameters. Field strength is another factor, but the data are equivocal for studies of coiled cerebral aneurysms (limited for de novo detection). See your neurologist or neurosurgeon for further discussion. http://link.springer.com/article/10.1007/s00234-008-0413-7

I did an MRA of the brain with no contrast and the results were normal brain MRA without evidence of intracranial aneurysm, stenosis, or arteriovenous malformation. Is the no contrast test good assurance or should I have done it with contrast ??
