VESICAL IMAGING-REPORTING AND DATA SYSTEM – A NEW APPROACH TO BLADDER CANCER STAGING

2022

The aim: To present the assumptions and to show the usefulness of Vesical Imaging-Reporting and Data System (VI-RADS) based on multiparametric magnetic resonance imaging (mpMRI) in the diagnostic pathway management of patients with a bladder cancer. Materials and methods: The review is based on available literature from last 10 years from PubMed database and the Przegląd Urologiczny journal focusing on articles on VI-RADS. Overall, 18 articles were included. Presented magnetic resonance images come from the examinations of the patients who were diagnosed with bladder cancer from 2019 to 2021 at Department of Diagnostic Imaging in University Clinical Hospital in Opole, Poland. Conclusions: T…

Imaging features of histological subtypes of hepatocellular carcinoma: Implication for LI-RADS

2021

Background & Aims The histopathological subtypes of hepatocellular carcinoma (HCC) are associated with distinct clinical features and prognoses. This study aims to report Liver Imaging Reporting and Data System (LI-RADS)-defined imaging features of different HCC subtypes in a cohort of resected tumours and to assess the influence of HCC subtypes on computed tomography (CT)/magnetic resonance imaging (MRI) LI-RADS categorisation in the subgroup of high-risk patients. Methods This retrospective institutional review board-approved study included patients with resected HCCs and available histopathological classification. Three radiologists independently reviewed preoperative CT and MRI exams. T…

On research work in information systems: Guidelines, recommendations and examples

2021

The most positive aspect of science is that the participants (researchers, reviewers and editors) control and evaluate their work themselves. Therefore they must be supported in one way or another. Fortunately, guidelines have been developed for different methodologies. However, today the guidelines are not very applicable. The first two sets of guidelines published (both positivist studies) had unusual problems. In this work, we analyze and improve the guidelines generally. Previously, selecting a methodology was the task of every researcher. It now seems that every researcher must also conduct a literature review and write a report. We consider methodology, literature review and writing "…
