If you find a better price on the retailer's website, let us know and we'll match it! Further acceleration of the single-point technique included elimination of a reference image (Yarnykh, 2016), which is usually needed in most qMT techniques, exclusion of B0 mapping due to a negligible effect of B0-related errors (Yarnykh et al., 2020), and a new data-driven algorithm for B1 non-uniformity correction (Yarnykh, 2021), which obviates commonly used in qMT protocols B1 mapping sequences. Wu T. L., Byun N. E., Wang F., Mishra A., Janve V. A., Chen L. M., et al. B2-20120091-4. Finally, MPF maps can be obtained using routine MRI equipment without modification of original manufacturers pulse sequences (Yarnykh et al., 2018b; Korostyshevskaya et al., 2019; Smirnova et al., 2021) thus facilitating clinical translation of this technology.

Direct comparison between apparent diffusion coefficient and macromolecular proton fraction as quantitative biomarkers of the human Fetal Brain Maturation. While MPF mapping has been in use for almost 20 years, the current literature lacks a review specifically focused on MPF as a myelin biomarker. Investigation of myelin damage, repair, and development in the central nervous system (CNS) for the understanding of pathological mechanisms and treatment monitoring in various neurological and psychiatric conditions using non-invasive imaging methods attracted substantial attention over past two decades (Heath et al., 2018; Piredda et al., 2021). Macromolecular proton fraction measurements were compared with histological myelin assessment in a variety of animal models including normal animal brain (Underhill et al., 2011; Khodanovich et al., 2017) and spinal cord (Dula et al., 2010), cuprizone-induced demyelination in mice (Thiessen et al., 2013; Turati et al., 2015; Khodanovich et al., 2017, 2019; Soustelle et al., 2019, 2021), experimental autoimmune encephalomyelitis in rats (Rausch et al., 2009), lipopolysaccharide-induced focal demyelination in rats (Janve et al., 2013), hexachlorophene-induced intramyelinic edema in rats (Harkins et al., 2013), genetic hypomyelination (Ou et al., 2009a,b; West et al., 2018) and hypermyelination (West et al., 2018) in mice, ischemic stroke in rats (Khodanovich et al., 2018, 2021), spinal cord injury in primates (Wang et al., 2016, 2019; Wu et al., 2020), and demyelinated peripheral nerve ex vivo (Odrobina et al., 2005; Ou et al., 2009a).

Idea creativa y diseo de campaa publicitaria. On-resonance saturation of water protons caused by readout RF pulses in fast gradient-echo sequences also can be used as a tool for MPF mapping (Gloor et al., 2008; Garcia et al., 2010; Bayer et al., 2021) based on steady-state models, where the signal is sampled as a function of the excitation pulse duration and flip angle. Data-Driven Retrospective Correction of B1 Field Inhomogeneity in Fast Macromolecular Proton Fraction and R1 Mapping. As a consequence, a popular myelin biomarker, myelin water fraction measured from multi-component relaxation analysis (MacKay et al., 1994; Deoni et al., 2008; Hwang et al., 2010) is also influenced by the iron content (Birkl et al., 2019). At the same time, due to dilution of the macromolecular content, MPF is affected by edema (Stanisz et al., 2004; Harkins et al., 2013; Khodanovich et al., 2018), which may cause up to 1015% overestimation of myelin loss by MPF in acute stroke (Khodanovich et al., 2018).
