ALVIN lateral ventricle segmentation

ALVIN - Automatic Lateral Ventricle delIneatioN is a fully automated algorithm which works within SPM8 to segment the lateral ventricles from structural MRI images.

ALVIN has been tested using the Brain Segmentation Testing Protocol and is valid for use in adults, patients with Alzheimer's disease and infants. The software is robust enough to work with T1 and T2 weighted images and takes approximately 10 minutes per subject. For information regarding the validation please see our paper published in Neuroimage.

Assessment

We tested the algorithm using the Brain Segmentation Testing Protocol and the results are given below.

*Intraclass Correlation Coefficient (single measure, 2-way mixed, consistency) for further information see our paper
