BACKGROUND AND PURPOSE: Recent work has shown a potential for excessive heating
of deep brain stimulation electrodes during MR imaging. This in vitro study investigates the …

BACKGROUND AND PURPOSE: Mental imagery involves rehearsing or practicing a task in
the mind with no physical movement. The technique is commonly used, but the actual …

PURPOSE: To estimate the prevalence, location, and type of cerebral aneurysms in patients
with adult polycystic kidney disease (PCKD) and identify associated risk factors. …

Objective The study objective was to perform a randomized trial of brain protection during
total aortic arch replacement and identify the best way to assess brain injury. Methods From …

Purpose. To evaluate magnet-related translational attraction for cardiac pacemakers, ICDs,
and an insertable loop recorder in association with exposure to “long-bore” and “short-bore” …

Objective: To determine if strategies used to safely scan nonpacemaker‐dependent patients
could be applied to facilitate safe MRI of pacemaker‐dependent patients. Interventions: Ten …

PURPOSE: To determine if calcification in the intervertebral disk is associated with
hyperintensity on T1-weighted spin-echo magnetic resonance (MR) images. MATERIALS AND …

Objective: Factors that restrict 3D TOF MRA are limited resolution, saturation of flow, and
degree of background suppression. We evaluated MRA for intracranial stenoses by using a 3D …

BACKGROUND AND PURPOSE: The use of 3.0-T MR systems is increasing worldwide. We
evaluated magnetic field interactions and translational attraction for 32 aneurysm clips in …

The study of blood flow by means of magnetic resonance techniques has led to a noninvasive
magnetic resonance angiography (MRA) technique for imaging large cerebral vessles. …
