Improved MRI resolution with Diffusion Dictionary Imaging (DDI)
Wang, Qing ; Wang, Yong
T-019608

— Technology Description Researchers at Washington University in St. Louis have developed MRI post-processing software capable of imaging cellular components. The software matches specific patterns with a dictionary of signals corresponding to cellular components. While the researchers have previous…

System and Method for Multi-modality Quantification of Neuroinflammation in Alzheimer ’s Disease
Benzinger, Tammie ; Wang, Qing ; Wang, Yong
T-016125

— Background: One in three seniors will die of Alzheimer’s disease (AD) or other neurodegenerative diseases. As the prevalence of AD increases rapidly, there is a strong need for early diagnoses and the ability to evaluate efficacy of drug treatments. Typically, a combination of neurological tes…

Quantify multi-tensor for improved CNS injury diagnosis using diffusion basis spectrum imaging (DBSI)
Song, Sheng-Kwei "Victor" ; Wang, Qing ; Wang, Yong
T-009943

— Background: Diffusion tensor imaging (DTI) has demonstrated sensitivity to detect pathologies in CNS white matter disorders. However, the capability of DTI to detect CNS white matter pathologies is confounded by the coexisting structural (crossing fibers) and pathological (inflammation associated ce…

Multi-Parametric Imaging of Tumor Heterogeneity Using Noninvasive, Non-radiative Water Diffusion
Benzinger, Tammie ; Guzman, Gloria ; Wang, Qing ; Wang, Yong
T-016652

— Background Currently, biopsies are the only definitive method to diagnose a brain tumor. While PET-CT is used for initial imaging and monitoring of the tumor, after completion of treatments, a 6-8-week delay is usually implemented to avoid false-positive results. Yet, the delay could also result in…
