Cellular tissues demonstrate impeded diffusion, which shows high signal intensity at higher b values and a corresponding low ADC value.
However, differentiation between different solid lesions is difficult based on visual assessment because these lesions, whether benign or malignant, demonstrate impeded diffusion on the high b value images.
Because they are more cellular, malignant hepatic lesions typically demonstrate impeded diffusion, which is manifested as high residual signal intensity on images obtained with high b values compared with background liver parenchyma as opposed to benign, non-solid lesions such as liver cysts and HHs.
In an indication of how seriously the government took the threat, it issued a warning to potential strikers on Saturday, saying it would "take necessary and resolute measures toward any attempt to demonstrate, impede traffic, hamper work in public facilities or to incite any of this".
(Skill levels ranged from beginning of pre-K to the beginning of second grade) Most of my students had behavior intervention plans, as the behaviors they demonstrated severely impeded on their ability to learn within a classroom.
A number of transcriptional repressors of CDH1 have been demonstrated to impede cell-cycle progression directly (reviewed in [ 22]).
In elegant work by Shogren-Knaak et al., the incorporation of acetylated K16 of H4 into nucleosomal arrays was demonstrated to impede the ability of chromatin to form cross-fibre interactions and this converted chromatin into an 'open' conformation [ 50].
Even ERK and Cdc42 were indicated to potentiate cells to migrate and invade [ 5, 23], this study demonstrated that moscatilin impeded migratory activity of H23 cells via ERK- and Cdc42-independent mechanisms.
Using a generic model of cell polarity, we demonstrated that input noise impeded the extent, accuracy, and smoothness of polarization.
Several hundred labor supporters demonstrated to block access to the Congress building to impede the start of a Senate debate on a new labor code.
