More info: First off, we need to know the story behind the tests as each test is ordered for a reason not "just because". If the test has low pretest probability of revealing the reason, then there is no good reason to order it. Mra assesses brain artery issues where mrv is related to brain venous health. Again, give us more details as why these tests are being considered.
