Evidence for cytotoxic edema in the pathogenesis of cerebral venous infarction

Autor: K P, Forbes, J G, Pipe, J E, Heiserman

Publikováno v: AJNR Am J Neuroradiol

BACKGROUND AND PURPOSE: The pathogenesis of cerebral venous infarction (CVI) remains controversial, with uncertainty over whether cytotoxic edema plays a role. Recent animal studies have shown that cytotoxic edema reliably occurs in acute CVI and pre

Incidence of postangiographic abnormalities revealed by diffusion-weighted MR imaging

Autor: P M, Britt, J E, Heiserman, R M, Snider, H A, Shill, C R, Bird, R C, Wallace

Publikováno v: AJNR Am J Neuroradiol

BACKGROUND AND PURPOSE: Occasionally we have observed anecdotal cases of asymptomatic hyperintensities on diffusion-weighted MR (DW-MR) examinations of the brain of patients who previously underwent routine cerebral angiography. These observations, a

Cerebral MR venography: normal anatomy and potential diagnostic pitfalls

Autor: R H, Ayanzen, C R, Bird, P J, Keller, F J, McCully, M R, Theobald, J E, Heiserman

Publikováno v: AJNR Am J Neuroradiol

BACKGROUND AND PURPOSE: MR venography is often used to examine the intracranial venous system, particularly in the evaluation of dural sinus thrombosis. The purpose of this study was to evaluate the use of MR venography in the depiction of the normal

MR angiography. Toward faster and more accurate methods

Autor: J E, Heiserman

Publikováno v: Neuroimaging clinics of North America. 9(2)

MR angiography is a class of methods developed to noninvasively evaluate vascular structures. After first reviewing the different approaches and comparing strengths and weaknesses, new methods to improve the quality or speed of acquisition of these i

The carotid artery: embryology, normal anatomy, and physiology

Autor: D H, Dungan, J E, Heiserman

Publikováno v: Neuroimaging clinics of North America. 6(4)

The anatomy and physiology of the normal carotid artery serves as a starting point for understanding and evaluating existing and new methods for diagnosing carotid artery disease. This article summarizes the history and state of the art of carotid ar

Serial magnetic resonance imaging in isolated angiitis of the central nervous system

Autor: Tajammul Ehsan, J. E. Heiserman, J. M. Powers, Shabih Hasan

Publikováno v: Neurology. 45(8)

Isolated angiitis of the central nervous system (IACNS) is a rare form of vasculitis restricted to the CNS.We report serial MRI findings in a biopsy-proven case of IACNS. MRI showed extensive white matter and subcortical disease. Before specific trea

Cerebral aneurysms

Autor: J E, Heiserman, C R, Bird

Publikováno v: Neuroimaging clinics of North America. 4(4)

Concurrent improvements in neurosurgical treatment and neuroradiologic evaluation of intracranial aneurysms have altered the approach to this condition. Meticulous panangiography remains the procedure of choice in the patient presenting with SAH to r

Intracranial MR angiography: its role in the integrated approach to brain infarction

Autor: B A, Johnson, J E, Heiserman, B P, Drayer, P J, Keller

Publikováno v: AJNR Am J Neuroradiol

PURPOSE: To determine the contribution of cranial MR angiography (MRA) for the evaluation of patients with acute and subacute brain infarction. METHODS: MR and MRA studies performed on 78 adult patients with acute and subacute stroke were retrospecti

MR angiography of cervical fibromuscular dysplasia

Autor: J E, Heiserman, B P, Drayer, E K, Fram, P J, Keller

Publikováno v: AJNR Am J Neuroradiol

The authors present examples of cephalic fibromuscular dysplasia (involving five vessels in two patients) using 2-D time-of-flight MR angiography and conventional angiography. Artifacts that can mimic the MR appearance of fibromuscular dysplasia will
