The authors identify eight areas of potential safety concern during clinical magnetic
resonance (MR) imaging. These include (a) biologic effects of the static magnetic field;(b) …

Although generally considered safe, magnetic resonance imaging (MRI) has a number of
safety issues, including the effects of high magnetic fields and radiofrequency pulses on the …

BACKGROUND AND PURPOSE: With developments in coil technology, intracranial
aneurysms are being treated increasingly by the endovascular route. Endovascular …

BACKGROUND AND PURPOSE: We assumed that patients with surgically treated
aneurysmal subarachnoid hemorrhage (SAH) might have more lesions than those revealed …

A method is presented for simulating susceptibility artifacts in 2D and 3D spin-echo and
gradient-echo imaging of arbitrary susceptibility distributions. The method incorporates …

OBJECTIVE: The goal of this study was to determine the frequency of lesions in the basal
frontotemporal area that were related to surgical damage to the brain tissue. METHODS: A …

We evaluated the ability of an ultrashort echo time (TE) three-dimensional (3D) time-of-flight
(TOF) magnetic resonance angiography (MRA) sequence to reduce the metal artefact of …

The use of CT angiography is described in three patients for the evaluation of intracranial
clips after surgery for an aneurysm. A postprocessing technique is described in which …

Purpose: the aim of this study was to evaluate the extent to which titanium aneurysm clips
could improve the quality of MR imaging compared with stainless steel clips, and to …

To assess ferromagnetic properties of intracranial aneurysm clips reported to be
nonferromagnetic, 1,765 Yasargil, 11 Sugita, and 15 Perneczky aneurysm clips were …
