Evaluation of Onyx HD-500 embolic system in the treatment of 84 wide-neck intracranial aneurysms.

Objective: We report our results using Onyx HD-500 (Micro Therapeutics, Inc., Irvine, CA) in the endovascular treatment of wide-neck intracranial aneurysms, which have a high rate of incomplete occlusion and recanalization with platinum coils.

Methods: Sixty-nine patients with 84 aneurysms were treated.

Diagnostic performance of stress perfusion and delayed-enhancement MR imaging in patients with coronary artery disease.

Purpose: To prospectively determine the accuracy of a combined magnetic resonance (MR) imaging approach (stress first-pass perfusion imaging followed by delayed-enhancement imaging) for depicting clinically significant coronary artery stenosis (> or = 70% stenosis) in patients suspected of having or known to have coronary artery disease (CAD), with coronary angiography serving as the reference standard.

Materials And Methods: The committee on human research approved the study protocol, and all participants gave written informed consent. This study was HIPAA compliant.

Dural sinus compartment in dural arteriovenous shunts: a new angioarchitectural feature allowing superselective transvenous dural sinus occlusion treatment.

Background And Purpose: The dural sinus occlusion has been shown to be effective in the treatment of some dural arteriovenous shunts (DAVS). No long-term results are available, however, regarding the significance of occlusion of a dural sinus. If the disease will stop or if other events will occur later in the remaining sinuses are not well known yet.

[Magnetic resonance imaging in 67 cases of glioblastoma multiforme and occurrence of metastases].

Purpose: The purpose of this paper is to demonstrate the main MRI characteristics of glioblastoma multiforme (GBM), the most common CNS primary tumor, emphasizing its location and the occurrence of metastases.

Method: The MR imaging of 67 pathologically proven cases of glioblastoma multiforme were retrospectively reviewed. The exams were realized in the period between 1995 and 2003, in one of three 1.

Analysis of parahippocampal gyrus in 115 patients with hippocampal sclerosis.

Purpose: Analysis of the parahippocampal gyrus (PHG) involvement in 115 patients with hippocampal sclerosis (HS) by MR imaging. The simultaneous occurrence of ipsilateral fornix (F) and mamillary body (MB) volume loss was checked also. These findings were correlated with the side of hippocampal involvement, the sex, patient s age, and the symptoms onset.

Ununsual manifestations of neurocysticercosis in MR imaging: analysis of 172 cases.

Purpose: The typical manifestations of neurocysticercosis are described widely in the literature. The purpose of this study is to demonstrate the uncommon presentations of different forms of neurocysticercosis in MR imaging.

Method: A retrospective analysis of 172 cases of neurocysticercosis in MR studies was carried out over a period of 13 years.

MR imaging for evaluation of lesions of the cranial vault: a pictorial essay.

Purpose: A variety of diseases affect the calvaria. They may be identified clinically as palpable masses or incidentally in radiologic examinations. There are many diagnostic possibilities, including congenital, neoplastic, inflammatory and traumatic lesions.
