Sentence examples for average attenuation values from inspiring English sources

The shift in average attenuation values may propagate through CT-AC and cause local artifacts that may be incorrectly interpreted in the clinical reading.

There was no significant difference between average attenuation values between naïve joints and μ-dHACM-treated MMT joints, suggesting the treatment maintained PG content comparable to intact joints.

Second, the mean CT values we measured were the average attenuation values on the transverse slices that showed the maximum diameter of the nodule, not the density of the entire nodule.

On the nonenhanced, pre-TACE baseline scans, the average attenuation value of the kidneys was 34.1 ± 4.1 HU (SD) in the combined cases and 36.7 ± 11.5 HU (not significant [NS]) in the cases that did have persistent global nephrograms.

Mean attenuation values were taken as an average of the mean Hounsfield numbers over these same areas of subcutaneous fat.

Table 1 shows the average quantitative values for the image noise, mean attenuation values and contrast-to-noise ratio of three different reconstruction algorithms.

The signal-to-noise ratio (SNR) was calculated as the mean attenuation value of the ROI/standard deviation of the surrounding oil attenuation value.

They also provide computer-derived measures such as mean lung attenuation (MLA) (representing the average global attenuation value of the pulmonary parenchyma), skewness (representing the extent of asymmetry of histograms), and kurtosis (representing the degree of "peakedness" of the histograms) [ 15].

The difference in attenuation between each tumor and surrounding parenchyma was calculated as follow: Attenuation difference =  mean tumor attenuation values - mean pancreas upstream and/or downstream attenuation values.

To estimate tumour heterogeneity, the average standard deviations of attenuation values within the tumour volumes were recorded as 22 HU at baseline versus 28 HU at interim for HD, and as 21 HU at baseline versus 27 HU at interim for NHL.

At each measurement site ROIs were placed on three adjacent slices and attenuation values were averaged before further analysis.
