Mri without contrast will reveal areas of atrophy, stroke, bleeding, tumors, hydrocephalus, etc, but will not clearly show certain ms lesions, aneurysms, avm's, some inflammatory problems, so, always discuss with your doctor as to why an ordered MRI might be done in a variety of ways. ...Read moreSee 2 more doctor answers

No: Noncontrasted MRI is the test of choice to radiographically diagnose Chiari's. Be aware that there is something called PHASE-CONTRAST MRI or abbreviated PC-MRI. This imaging technique can be used (and is very useful in some cases when looking at headaches associated with Chiari's) to image the malformation. It DOES NOT utilize IV-contrast though the word "contrast" is in the name of the test. ...Read more

An mrv (mr venography) uses special sequences to look at the venous structures (dural venous sinuses) around the brain. The main indication for mrv is to look for a clot or stenosis. Typically this is also done with IV contrast for better image quality. ...Read more
