The objective of this study was to assess the ability of a quantitative software-aided approach
to improve the diagnostic accuracy of 18 F FDG PET for Alzheimer’s dementia over visual …

Background and Purpose To evaluate an automatic multi-atlas-based segmentation method
for generating prostate, peripheral and transition zone (PZ/TZ) contours on MRIs with and …

Purpose To assess the performance and limitations of contour propagation with three commercial
deformable image registration (DIR) algorithms using fractional scans of CT‐on‐rails (…

Purpose/Objectives Manual contouring techniques are tedious and time consuming, increasing
the importance of automatic segmentation approaches to reduce the contouring burden. …

Purpose Validating deformable multimodality image registrations is challenging due to
intrinsic differences in signal characteristics and their spatial intensity distributions. Evaluating …

Purpose This study aims at investigating the impact of imaging modality, deformable image
registration (DIR) algorithm, and dose accumulation interval in the estimation of the …

This study evaluated performance of a commercially available standardized software program
for calculation of florbetapir PET standard uptake value ratios (SUVr) in comparison with …

1523 Objectives Generating liver volumes of interest (VOIs) is important for both therapy and
surgical planning. Manual segmentation approaches are time consuming. In this study we …
