However, due to the influence of various factors including imaging protocol, lesion size, and image processing, the effectiveness of PET/CT texture features is still under argumentation [21], and standardization of texture feature calculation is highly required [22].
The Magnetic Resonance Imaging technique could help to improve Doppler flow calculations, thereby allowing standardization of protocols.
The average of the corresponding normal limits was taken as the mean, and the range of the normal limits divided by 4 as the standard deviation in the standardization calculations.
And the standardization of scores (percentage) of them were calculated.
Indeed, standardization of ventilatory settings at baseline and after 24 h, and thus calculation of the PaO2/FiO2, may be crucial for appropriate stratification and patient selection bias minimization [43], and the same may apply for SpO2-based markers.
There are several possible reasons explaining this difference, including the use of different hardware, absence of standardization of image acquisition (choice of different b values), various methods for ADC calculation and different patient populations.
Standardization of experimental uncertainty procedure, identification of all possible elemental error sources, common methods for calculation of certain properties, and standardization of experimental procedures are required for consistent interpretation of experimental results and uncertainties associated with the experiments.
In addition to tumor volume calculation, accurate automatic segmentation methods additionally have the potential to reduce the variability and increase the standardization of other measurements and protocols, including the quantification of edema or necrosis.
This has led to advances, but the standardization of disease classification requires the work of experts.
Even with the standardization of some aspects of divorce, the right strategy matters.
