PSF-choice: a novel MRI method for shaping point-spread functions in phase-encoding dimensions.
An imaging method to obtain arbitrary point-spread functions (PSFs) in phase-encoding dimensions is described. This method, called PSF-Choice, is particularly relevant for applications, such as spectroscopic imaging, in which only a very few phase encodes are acquired and ringing artifact can be a serious problem. PSF-Choice uses partial 2D RF excitations to produce aliased excitations that are...
متن کاملProstate cancer localization with dynamic contrast-enhanced MR imaging and proton MR spectroscopic imaging.
PURPOSE To prospectively determine the accuracies of T2-weighted magnetic resonance (MR) imaging, dynamic contrast material-enhanced MR imaging, and quantitative three-dimensional (3D) proton MR spectroscopic imaging of the entire prostate for prostate cancer localization, with whole-mount histopathologic section findings as the reference standard.

متن کاملProstate cancer: sextant localization at MR imaging and MR spectroscopic imaging before prostatectomy--results of ACRIN prospective multi-institutional clinicopathologic study.
PURPOSE To determine the incremental benefit of combined endorectal magnetic resonance (MR) imaging and MR spectroscopic imaging, as compared with endorectal MR imaging alone, for sextant localization of peripheral zone (PZ) prostate cancer. MATERIALS AND METHODS This prospective multicenter study, conducted by the American College of Radiology Imaging Network (ACRIN) from February 2004 to Ju...
متن کاملNon-Fourier Spatial Encoding for Improved Point-Spread-Functions in Hyperpolarized 13C CSI Acquisitions
INTRODUCTION: Metabolic imaging using pre-polarized substrates labeled with a 13C nucleus has proven to be a promising new tool (1). Often, chemical-shift imaging (CSI) acquisitions are used to map the 13C resonances over 2D or 3D volumes so that 13C metabolic data from various tissues can be compared. Due to the time constraints imposed by the relatively short lifetime of the hyperpolarized st...
متن کاملExperimental evaluation and basis function optimization of the spatially variant image-space PSF on the Ingenuity PET/MR scanner.
PURPOSE The Ingenuity time-of-flight (TF) PET/MR is a recently developed hybrid scanner combining the molecular imaging capabilities of PET with the excellent soft tissue contrast of MRI. It is becoming common practice to characterize the system's point spread function (PSF) and understand its variation under spatial transformations to guide clinical studies and potentially use it within resolu...
