Sentence examples for measurement of input function from inspiring English sources

Not surprisingly, the reference tissue model is not affected by errors in the measurement of input function.

Measurement of arterial input function or generation of a normalising function based on nearby normal tissues are methods that are under development.

Due to experimental limitations, only sums of several species were measurable leading to the following observables: where y1 is the total amount of phosphorylated STAT5 in the cytoplasm, y2 the total amount i.e. unphosphorylated and phosphorylated STAT5 in the cytoplasm and y3 is the measurement of the input function i.e. the amount of the Epo-induced phosphorylation of EpoR.

This could be between-subject differences, physiological fluctuations, or methodological errors pertaining to the measurement of the input function and the involved corrections [32, 33] or in the selection of the venous ROI and the arterial input function in perfusion CT [23, 34].

The accurate measurement of the input function requires arterial blood sampling.

For most previous studies, there was no gold standard measurement of the input function, and therefore, no basis for IDIF correction.

The accurate measurement of the input function theoretically requires arterial blood sampling.

We augmented this high-quality image data with continuously sampled arterial measurements for input function validation.

These results are similar to measurements of the input function of the araBAD reporter strain in wild-type MG1655 (U429) [ 35], and are consistent with the expected value for a curve with Hill coefficient equal to n = 1, in which R = 81.

In contrast, the accuracy of input functions estimated using two or three arterial concentration measurements was independent of initial parameter values.

Cerebral blood perfusion parameters including rel-CBV and -CBF maps were derived by defining an RoI at the contralateral hemisphere covering the origin of the right MCA to allow measurement of the arterial input function, from which pixels representative of the right MCA branch were selected.
