Sentence examples for using the monoexponential model from inspiring English sources

Traditionally, breast ADCs have been calculated using the monoexponential model.

DW-MR signal decay is most commonly analyzed using the monoexponential model [ 26, 27]: (3) ADC = ln ⁡ ⁡ S 0 / S b b, where S b is the MRI signal intensity with diffusion weighting b, S0 is the nondiffusion-weighted signal intensity, and ADC is the apparent diffusion coefficient.

Fitted curves using the monoexponential model and all b values (B0, dotted black line), only low b values (B7, dashed red line) and only high values (B4, dashed blue line) are displayed together with the fitted curve obtained using the biexponential model with all b values (B0biexp, solid green line).

Statistical analysis was performed on median ADCBXs, Ds, D*s and fps of individual breast lesion ROIs.> -wrap-foot> a X ranges from 0 to 12 for b value combinations used in the monoexponential model, and it is 0biexp for the b value combination used in the biexponential model.

The 13 different combinations of b values, B0 B12, used in the monoexponential model are shown in Table  1.

The release profiles were modeled using the monoexponential and biexponential equations.

In our study the biexponential model provided poorer fitting than did the monoexponential model.

All ROI voxels could be fitted to the monoexponential model, whereas on average 79 ± 15%% (range, 37 100 %) of all voxels were satisfactorily fitted to the biexponential model.

Unlike these three co-solvents, EEA showed a good fit with the monoexponential model for the hypsochromic shift, i.e., with a time constant of ca. 0.6 min.

To reduce perfusion effects and obtain flow-insensitive ADC or ADCslow, it has been recommended to omit low b values from the monoexponential model [ 1].

The purpose of this study was to examine how the choice of b values included in the monoexponential model affects calculated ADCs and also to compare these with Ds derived from the biexponential model.
