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 …

PURPOSE: To prove that the contrast of enhancing brain lesions on post-gadolinium T1-weighted
spin-echo (SE) images can be statistically significantly improved with magnetization-…

Cerebral blood flow was quantitatively mapped by monitoring the cerebral washout of H 2 17
O using rapid, single‐shot proton NMR imaging. H 2 17 O acts as a freely diffusible contrast …

A variety of methods has been developed for quantitating flow in vivo. These are usually
based on the principles of velocity-phase or TOF information. The former allows a point-by-point …

In this issue of the AJNR, Bauer et al (page 366) publish their second major article showing
the high accuracy of MR diffusion-weighted scanning in discriminating acute benign from …

PURPOSE: Rapid, dynamic, contrast material-enhanced magnetic resonance imaging was
performed to evaluate the early enhancement patterns of normal pituitary structures, …

MR images of a phantom simulating enhancing brain lesions. AJNR Am J Neuroradiol 18:147-…

Two cases of trilateral retinoblastoma (a syndrome of midline, undifferentiated, intracranial
tumor in a child with hereditary, bilateral ocular retinoblastoma) are described, one with a …

PURPOSE: To evaluate whether magnetization transfer (MT) can improve image contrast
on gradient-recalled echo (GRE) magnetic resonance (MR) images of the cervical spine. …

Coronary artery imaging with magnetic resonance imaging carries the potential for a
noninvasive, essentially risk-free screening test for those at risk for coronary heart disease. Many …
