Hyperpolarized 3He Magnetic Resonance Functional Imaging Semiautomated Segmentation
Abstract
RATIONALE AND OBJECTIVES: To improve intra- and interobserver variability and enable the use of functional magnetic resonance imaging (MRI) for multicenter, multiobserver studies, we generated a semiautomated segmentation method for hyperpolarized helium-3 ((3)He) MRI. Therefore the objective of this study was to compare the reproducibility and spatial agreement of manual and semiautomated segmentation of (3)He MRI ventilation defect volume …
