title: Even echo MR rephasing in the diagnosis of giant intracranial aneurysm.
abstract: Blood flow magnetic resonance (MR) imaging has played a significant role in the evaluation and differentiation of vascular from nonvascular lesions, particularly as it applies to the CNS. Even echo rephasing and high velocity signal loss are two phenomena that are useful in differentiating primary vascular lesions that exhibit either slow laminar flow or rapid flow from solid masses or clot-containing vascular lesions. Application of these two basic principles of blood flow imaging with MR aided in establishing the correct diagnosis in a case of giant intracranial aneurysm.
