Intravoxel incoherent motion MRI in neurological and cerebrovascular diseases.
TL;DR: The combination of IVIM and arterial spin labeling MRI enables the estimation of water permeability across the blood-brain barrier (BBB), suggesting a potential imaging biomarker for disrupted-BBB diseases.

Contrast‐agent‐free state‐of‐the‐art MRI on cerebral small vessel disease—part 1. ASL, IVIM, and CVR
André Monteiro Paschoal,Kaio Felippe Secchinatto,Pedro Henrique Rodrigues da Silva,Maria Clara Zanon Zotin,Antonio Carlos dos Santos,Anand Viswanathan,Octavio M. Pontes-Neto,Renata F. Leoni +7 more
TL;DR: MRI techniques such as arterial spin labeling (ASL), diffusion tensor imaging, functional MRI, and intravoxel incoherent motion (IVIM) applied to cSVD are promising, noninvasive tools to explore questions that have not yet been clarified about this clinical condition.

Effects of global signal regression and subtraction methods on resting-state functional connectivity using arterial spin labeling data
João Paulo Santos Silva,Luciana Monaco,André Monteiro Paschoal,Icaro Agenor Ferreira de Oliveira,Renata F. Leoni +4 more
TL;DR: It is shown that both RMAGSF filtering and subtraction method might influence resting-state FC results, especially in an ROI level, consequently affecting FC analysis and its interpretation, and changes were prominent in FC values and their statistical significance.

Three-dimensional gradient and spin-echo readout for time-encoded pseudo-continuous arterial spin labeling: Influence of segmentation factor and flow compensation.
TL;DR: In this article, the effect of 3D gradient and spin-echo (GRASE) readout segments on temporal SNR and image blurriness for time-encoded pseudo-continuous arterial spin labeling was evaluated.

Contrast agent‐free state‐of‐the‐art magnetic resonance imaging on cerebral small vessel disease – Part 2: Diffusion tensor imaging and functional magnetic resonance imaging
P. Silva,André Monteiro Paschoal,Kaio Felippe Secchinatto,Maria Clara Zanon Zotin,Antônio Carlos Santos,Anand Viswanathan,Octavio M. Pontes-Neto,Renata F. Leoni +7 more
TL;DR: The application of contrast agent‐free, state‐of‐the‐art MRI techniques has provided a complete picture of cSVD markers and tools to explore questions that have not yet been clarified about this clinical condition.
