Publikováno v: PLoS ONE, Vol 9, Iss 1, p e84764 (2014)
The systematic investigation of susceptibility-induced contrast in MRI is important to better interpret the influence of microvascular and microcellular morphology on DSC-MRI derived perfusion data. Recently, a novel computational approach called the

Abstract Sampling restrictions have hindered the comprehensive study of invasive non-enhancing (NE) high-grade glioma (HGG) cell populations driving tumor progression. Here, we present an integrated multi-omic analysis of spatially matched molecular

Moving Toward a Consensus DSC-MRI Protocol: Validation of a Low–Flip Angle Single-Dose Option as a Reference Standard for Brain Tumors
Autor: Natenael B. Semmineh, Brent R. Logan, Jennifer Connelly, Barrett J. Anderies, Ashley M. Stokes, Scott D. Rand, Melissa Prah, Leland S. Hu, C.C. Quarles, Y. Liu, Grayson L. Baird, Y. Zhou, Kathleen M. Schmainda, Jerrold L. Boxerman
Publikováno v: American Journal of Neuroradiology.
BACKGROUND AND PURPOSE: DSC-MR imaging using preload, intermediate (60°) flip angle and postprocessing leakage correction has gained traction as a standard methodology. Simulations suggest that DSC-MR imaging with flip angle = 30° and no preload yi

Systematic assessment of multi-echo dynamic susceptibility contrast MRI using a digital reference object
Autor: Ashley Nespodzany, Laura C. Bell, Ashley M. Stokes, C. Chad Quarles, Natenael B. Semmineh
Publikováno v: Magn Reson Med
PURPOSE Brain tumor dynamic susceptibility contrast (DSC) MRI is adversely impacted by T1 and T2∗ contrast agent leakage effects that result in inaccurate hemodynamic metrics. While multi-echo acquisitions remove T1 leakage effects, there is no con

Optimization of Acquisition and Analysis Methods for Clinical Dynamic Susceptibility Contrast (DSC) MRI Using a Population-based Digital Reference Object
Autor: C.C. Quarles, Ashley M. Stokes, Leland S. Hu, Jerrold L. Boxerman, Laura C. Bell, Natenael B. Semmineh
BACKGROUND AND PURPOSE: The accuracy of DSC-MR imaging CBV maps in glioblastoma depends on acquisition and analysis protocols. Multisite protocol heterogeneity has challenged standardization initiatives due to the difficulties of in vivo validation.

Validation of a T1and T2* leakage correction method based on multiecho dynamic susceptibility contrast MRI using MION as a reference standard
Autor: Ashley M. Stokes, Natenael B. Semmineh, C. Chad Quarles
Publikováno v: Magnetic Resonance in Medicine. 76:613-625
Purpose A combined biophysical- and pharmacokinetic-based method is proposed to separate, quantify, and correct for both T1 and T2* leakage effects using dual-echo dynamic susceptibility contrast (DSC) acquisitions to provide more accurate hemodynami
