Diffusion tensor imaging of the hippocampus reflects the severity of hippocampal injury induced by global cerebral ischemia/reperfusion injury.

Wen-Zhu Wang, Xu Liu, Zheng-Yi Yang, Yi-Zheng Wang, Hai-Tao Lu,

At present, predicting the severity of brain injury caused by global cerebral ischemia/reperfusion injury (GCI/RI) is a clinical problem. After such an injury, clinical indicators that can directly reflect neurological dysfunction are lacking. The change in hippocampal microstructure is the key to memory formation and consolidation. Diffusion tensor imaging is ... Read more >>

The role of spatial embedding in mouse brain networks constructed from diffusion tractography and tracer injections.

Scott Trinkle, Sean Foxley, Gregg Wildenberg, Narayanan Kasthuri, Patrick La Rivière,

Diffusion MRI tractography is the only noninvasive method to measure the structural connectome in humans. However, recent validation studies have revealed limitations of modern tractography approaches, which lead to significant mistracking caused in part by local uncertainties in fiber orientations that accumulate to produce larger errors for longer streamlines. Characterizing ... Read more >>

A critical review of connectome validation studies.

Tabinda Sarwar, Kotagiri Ramamohanarao, Andrew Zalesky,

Diffusion MRI tractography is the most widely used macroscale method for mapping connectomes in vivo. However, tractography is prone to various errors and biases, and thus tractography-derived connectomes require careful validation. Here, we critically review studies that have developed or utilized phantoms and tracer maps to validate tractography-derived connectomes, either ... Read more >>
