(1999) [ ] , Healthy adult human patients , 10 , CBV measured by contrast enhanced MRI , Critikon Cerebral RedOx Monitor-2020 using a sensor with two receiving channels for different distances. Wavelength is not specified. , CBV NIRS (A function of total Hb) , Group of healthy adult humans (6 F/4 M) Measurements of CBV NIRS were taken before and after patients were in the MRI machine Measurements for CBV MRI were taken at baseline over a period of 2 min , Mean values obtained for CBV NIRS and CBV MRI were not statistically different when a paired sample t -test and Wilcoxon signed rank test were performed. Mean CBV NIRS was 8.6 ± 1.3 mL/100 g and the mean CBV MRI was 7.1 ± 2.5 mL/100 g The average difference across measurements for CBV NIRS was 11.5% Methods for obtaining values of CBV NIRS and CBV MRI were not correlated, both Pearson and Spearman correlation testing failed to reach statistical significance , Small sample size Measurements of the two methods were not taken simultaneously No bias assessment performed.
