Furthermore, Eq. 9 promotes varying degrees of diffusions depending upon the local image structures, particularly edges and contours.
Calculation of the ADC requires acquisition of at least two series of DW MR images with different degrees of diffusion-weighting (b value).
The majority of studies have used the metric of mean diffusivity (MD), which assesses the average degree of diffusion in all directions, as opposed to quantifying directionality.
This parameter represents the degree of diffusion weighting of the sequence, determined by the application of specific magnetic field gradients, and is measured in s/mm2.
The ADC value can theoretically be used to characterise tissues, as the degree of diffusion is correlated to cellular density and extracellular space volume [8, 9].
This study was conducted to assess the degree of diffusion of hysteroscopic surgery in gynaecological practice in The Netherlands in order to guide further implementation.
However, the degree of diffusion depends not only on the interlayer thickness, but also on the thickness of the high-κ film.
As the particle diameter is increased, the enhancement factor decreases due to an increasing degree of diffusion limitation.
Several studies have reported that lymph node metastases have a higher degree of diffusion restriction than normal lymph nodes, and this can be assessed quantitatively using ADC values [57, 58, 59, 60, 61, 62, 63, 64].
If it is true that the political situation determined the degree of diffusion of non-indigenous architectural concepts in this region, the new findings can be interpreted as supporting the hypothesis that Basque farmhouses reflect a regionally-developed building tradition.
