A Contrast Synthesized Thalamic Nuclei Segmentation Scheme using Convolutional Neural Networks
Lavanya Umapathy, Mahesh Bharath Keerthivasan, Natalie M. Zahr +2
Thalamic nuclei have been implicated in several neurological diseases. WMn-MPRAGE images have been shown to provide better intra-thalamic nuclear contrast compared to conventional…
Fast automatic segmentation of thalamic nuclei from MP2RAGE acquisition at 7 Tesla
Ritobrato Datta, Micky K. Bacchus, Dushyant Kumar +6
Purpose: Thalamic nuclei are largely invisible in conventional MRI due to poor contrast. Thalamus Optimized Multi-Atlas Segmentation (THOMAS) provides automatic segmentation of 12…
A systematic comparison of structural, structural connectivity, and functional connectivity based thalamus parcellation techniques
Charles Iglehart, Martin Monti, Joshua Cain +2
The thalamus consists of several histologically and functionally distinct nuclei increasingly implicated in brain pathology and important for treatment, motivating the need for dev…
Automated Thalamic Nuclei Segmentation Using Multi-Planar Cascaded Convolutional Neural Networks
Mohammad S Majdi, Mahesh B Keerthivasan, Brian K Rutt +3
A cascaded multi-planar scheme with a modified residual U-Net architecture was used to segment thalamic nuclei on conventional and white-matter-nulled (WMn) magnetization prepared…
T2-weighted Spine Imaging using a Single-Shot Turbo Spin Echo Pulse Sequence
Mahesh Bharath Keerthivasan, Blair Winegar, Jennifer L Becker +1
T2 weighted imaging of the spine is commonly performed using fast spin echo (FSE/TSE) based sequences, resulting in long scan times and vulnerability to motion artifacts. While sin…
