We previously reported on a case-control study of 174 breast cancer cases and 348 controls nested within the Singapore Breast Screening Project (SBSP) using the Tabar qualitative measure of breast density (Jakes et al, 2000; Duffy et al, 2004).
Wilcoxon signed rank and 2-sample tests were used to compare the qualitative measures, CNR and SNR, for DECT and 120-kVp images.
The main strengths of this study include its large prospective design, complete recruitment and follow-up, and the use of semi-quantitative exposure measures that improve on the qualitative measures used in previous studies of pesticide exposure.
The proposed scheme is evaluated with the help of synthetic as well as the real images and compared with other state-of-the-art schemes using a qualitative measure.
The quantitative and the qualitative measures used as the quality metrics demonstrated the ability of the proposed method for noise cancellation.
The difficulty of using a qualitative measure weighs on city officials' minds as they prepare the outlines of a new testing contract that will go out for competitive bidding to the nation's testing publishers in the fall.
Allele frequency estimation success, along with false positive and negative call rates, improved significantly when using a qualitative measure of SNP call quality.
Challenging future goals are to compare the pre-service teachers' perceptions with the evaluation of the group product as a more objective measure, as well as to trace the development of their knowledge through their contributions to the forum, using also qualitative measures to detect critical episodes in their interaction and the effect of these on both TPACK and Cognitive presence.
To date, most studies examining the association of breast density with tumor characteristics have used a qualitative measure of density (for example, BI-RADS), lacked information on covariates, and differed in whether and how the cancer was detected (by screening or other means).
We used a qualitative measure called Proportional Similarity to test whether a subset selection of image descriptors was necessary to avoid an overfitting.
