Analysis of the spatial characteristics of metabolic abnormalities in newly diagnosed glioma patients.
To evaluate the role of 3D MR spectroscopic imaging (MRSI) as a tool for characterizing heterogeneity within a lesion in glioma patients. ⋯ These 3D-MRSI data provide important additional information to conventional MRI for evaluating and characterizing gliomas.

Hybrid phased array for improved internal auditory canal imaging at 3.0-T MR.
To develop and evaluate a hybrid phased array for internal auditory canal (IAC) imaging at 3.0 T. ⋯ This hybrid array combined with three-dimensional fast spin-echo (FSE) acquisition resulted in improved high spatial resolution IAC imaging.

Dynamic coronary MR angiography and first-pass perfusion with intracoronary administration of contrast agent.
To evaluate whether dynamic imaging of the coronary arteries can be performed with intracoronary infusion of low-dose gadolinium (Gd)-based contrast agent and assess the effect of long duration and multiple infusions on the image signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR). ⋯ These studies demonstrated that, using intracoronary infusion of Gd, coronary magnetic resonance angiography (MRA) can be performed with high temporal resolution, and multiple low-dose slow infusions of Gd-based MR contrast agent can be performed without compromise of the vessel SNR and CNR.
