One patient who received 4 months of neoadjuvant imatinib prior to surgery also showed decreased attenuation of the tumor.
Air-trapping (represented by areas of decreased attenuation) secondary to focal areas of bronchial or bronchiolar obstruction can be accentuated at expiration.
The presence of emphysema was defined as well-demarcated areas of decreased attenuation in comparison with a contiguous normal lung and marginated by a very thin or no wall with upper zone predominance.
On CT, acute interstitial pancreatitis may be characterised by fluid collections, peripancreatic fat stranding, focal areas of decreased attenuation, or diffuse oedema within the pancreas (Fig. 6) [34].
Emphysema was defined as well-demarcated areas of decreased attenuation in comparison with contiguous normal lung and marginated by a very thin (<1 mm) or no wall with upper zone predominance.
The decreased attenuation pattern is defined as areas of low density corresponding to parenchymal destruction and reduced perfusion, and attenuation of the pulmonary vasculature.
As suggested by previous models [ 20, 21], and also apparent in our simulations, attenuation of signal response occurs after an apparent reduction in signal duration caused by decreasing levels of EGF stimulus.
Immunosuppressive agents usually act by decreasing protein expression, which leads to attenuation of the immune response and induces a state of tolerance [ 40].
Indeed, as shown in Figure 8d, attenuation of UPR, obtained by decreasing unfolded protein accumulation (CHX), increasing cell folding ability (4-PBA) or inhibiting a downstream pro-apoptotic signaling (JNK inhibitor SP600125), protects transformed cells from glucose-dependent death.
> Whereas the convolution filter did not significantly affect the attenuation values of the lumen and the surrounding, sharper filters decreased the attenuation of the plaque and, conversely, increased the attenuation of the calcification with both solutions (Fig. 2).
