“…No change (Faraco et al, 2015b) Increase (slight) (Faraco et al, 2015b) SvO2 Increase (Faraco et al, 2015b) Increase (Faraco et al, 2015b) * Assumed (See section 4.3) † Contributing effects of hypocapnia for non-isocapnic stimuli Hct typically ranges between 36-54% (Billett, 1990), with natural fluctuations arising as a function of age, (Adeli et al, 2015;Daniel, 1973) and potentially race (Beutler and West, 2017;Cheng et al, 2004). The need for individualised knowledge of Hct becomes critical in anaemia, with significant reductions observed in a wide range of pathology (Babitt and Lin, 2012;Goodnough et al, 2003;Muncie and Campbell, 2009;Rees et al, 2010;van Iperen et al, 2001), secondary to therapy (Groopman and Itri, 1999;Ludwig et al, 2004;Rodgers et al, 2012), and in response to poor nutrition (Baker and Demaeyer, 1979 (Joseph et al, 2016;Li et al, 2017). Furthermore, Hct is known to be reduced in microvasculature in comparison to larger vessels.…”

The ultimate goal of calibrated fMRI is the quantitative imaging of oxygen metabolism (CMRO), and this has been the focus of numerous methods and approaches. However, one underappreciated aspect of this quest is that in the drive to measure CMRO, many other physiological parameters of interest are often acquired along the way. This can significantly increase the value of the dataset, providing greater information that is clinically relevant, or detail that can disambiguate the cause of signal variations. This can also be somewhat of a double-edged sword: calibrated fMRI experiments combine multiple parameters into a physiological model that requires multiple steps, thereby providing more opportunity for error propagation and increasing the noise and error of the final derived values. As with all measurements, there is a trade-off between imaging time, spatial resolution, coverage, and accuracy. In this review, we provide a brief overview of the benefits and pitfalls of extracting multiparametric measurements of cerebral physiology through calibrated fMRI experiments.

“…За поширеністю, АХЗ є другою після ЗДА у хворих із гострими або хронічними імуноактивними процесами, з чим і пов`язана її друга назва «анемія хронічного запалення» [7][8][9][10]. Найчастіше така анемія асоційована із інфекційними -гострими та хронічними бактеріальними, паразитарними та грибковими захворюваннями (18-95% випадків) [11][12][13], онкологічними процесами -30-77% [12][13][14][15][16], автоімунними (ревматоїдний артрит, васкуліти, саркоїдоз, запальні захворювання товстої кишки) -8-71% [17][18][19][20], хронічними захворюваннями нирок -23-50% [21][22][23]. Зазвичай, АХЗ є нормоцитарною та нормохромною [8][9][10]24], але АХЗ може бути гіпопроліферативною, а іноді й мікроцитарною, тому диференціальна діагностика має включати залізодефіцитну анемію (ЗДА).…”
