Dear Annals of Medical Research Readers

As of the end of March 2021, I have started to work as Chief Editor at Annals of Medical Research. Our journal is the official publication of Inonu University Medical Faculty and published uninterruptedly for 28 years.  Our Journal, which is online as an open access journal with monthly free access, is being scanned in many national and international indexes (ULAKBIM TR Dizin, Turkish Medline, EBSCO, Google Scholar, etc.). I would like to thank the Editors before me who contributed to this level. Our primary goal is to ensure the maintenance of this good state of the journal and to ensure that it is scanned in prestigious international indexes (Pubmed Central, SCI-Expended, etc.). In order to achieve these goals, it depends on the original research articles that can be cited and the articles published in our Journal to be cited sufficiently in other international journals. The contributions of our readers, reviewers and authors in achieving this goal are of great importance.

I hope to announce the news that we have reached our goals as soon as possible.

Abstract

Aim: To evaluate the discrimination ability of computed tomography (CT) texture analysis between pancreatic ductal adenocarcinoma (PDAC) and hypovascular pancreatic neuroendocrine neoplasm (PNEN).
Materials and Methods: Preoperative CT examinations of 49 patients with pathologically proven PDAC (35) and hypovascular PNEN (14) were evaluated retrospectively. Images in the portal vein phase of each tumor were assessed by two radiologists. Differences in texture features between PDACs and PNENs were analyzed with Mann Whitney-U test and logistic regression analysis.
Results: Patients with PNEN (50.4 ± 11.7 y) were significantly younger than the patients with PDAC (62.0 ± 11.1y) (p = 0.002). Nine CT texture features were found statistically significant between groups. NGLDM and GLZLM texture features showed the best diagnostic performance on multivariate analysis. Between these parameters, NGLDM_ Busyness showed the best diagnostic performance with the AUC value of 0.865. Combination of NGLDM_ Busyness and GLZLM_LZLGE improved the diagnostic performance at a significant level (AUC = 0.906, 95% CI = 0.747-0.988, p 0.05).
Conclusion: CT texture features of single portal venous phase images may help to discriminate hypovascular PNEN from PDAC.
