Example sentences for: cbf

How can you use “cbf” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • The visual CBF reactivity (ΔCBF react ) following visual stimulation was calculated in each subject by subtracting the visual cortex resting cerebral blood flow from the mean visual activation CBF.

  • In order to characterize the visual activation response further, a specific region of interest (ROI) was used that included Brodmann areas 17, 18 and 19 as determined from the Talairach-Tournoux electronic brain atlas [ 17 ] . The visual ROI was derived from T1 MRI template which was then used to mask the SPM registered CBF images prior to calculation of the visual CBF responses.

  • The CBF response curve to acetazolamide can be considered like a high pass filter with an onset time constant to a steady state τ 1 and an offset time constant of τ 2 . Alteration and prolongation of τ 2 will correspond to prolonged cerebral vascular response time . An important concept of a high pass filter is that the system response is dependent on both the resistive (R) and capacitative (C) elements.

  • A significant reduction (p = 0.036) in the global CBF was found 30-minutes post-acetazolamide in the ERT group compared to the placebo group.

  • Resting and post-acetazolamide global CBF values were not significantly different between the control group and the untreated patient group for either the twenty-minute or thirty-minute time point.
