SPGR 0.938 x 0.938 x 0.934 physical characteristics and general acquisition parameters of
the PET and MRI scanners used in each center. Data analyses were performed with all 24 …

Purpose Statistical parametric mapping (SPM) and NEUROSTAT (NS) are widely used for
intersubject statistical analysis of brain images. We investigated individual anatomical …

Accurate localization of an imaging plane of interest is often needed prior to a positron
emission tomographic (PET) study. We have developed a simple method for accurate and …

Objective We developed a new computed tomography (CT)-based spatial normalization
method and CT template to demonstrate its usefulness in spatial normalization of positron …

Materials and methods Ninety patient scans acquired on the Philips CPET scanner at our
institution were reconstructed using 2.5-D RAMLA and 3-D RAMLA with differing …

A cylinder phantom positioned at a slightly oblique angle with respect to the z-axis of a PET
scanner allows for fine sampling of the edge-spread function. We show how this technique …

The use of different scanners, acquisition protocols, and reconstruction algorithms has been
identified as a problem that limits the use of PET in multicenter trials. The aim of this project …

Abstract Objectives Clinical PET/MR requires the use of patient positioning aids to
immobilize and support patients for the duration of the combined examination. Ancillary …

Accurate anatomic localization of functional abnormalities seen with PET is known to be
problematic. Even though nonspecific tracers such as 18 F-FDG visualize certain normal …

1694 Objectives: Statistical comparison of functional brain volumes often requires an
alignment step of each brain volume into a common template space to ensure that …
