The aim of the study was to build the reporting scheme of chest CT in COVID-19 pneumonia. Methods A team of experts, of the Italian Society of Medical and Interventional Radiology (SIRM), has been recruited to compose a consensus panel. They used a modified Delphi process to build a reporting scheme and expressed a level of agreement for each section of the report. To measure the internal consistency of the panelist ratings for each section of the report, a quality analysis based on the average inter-item correlation was performed with Cronbach’s alpha (Cα) correlation coefficient. Results The overall mean score of the experts and the sum of score were 3.1 (std.dev. ± 0.11) and 122 in the second round, and improved to 3.75 (std.dev. ± 0.40) and 154 in the third round. The Cronbach’s alpha (Cα) correlation coefficient was 0.741 (accep...

A slightly more favourable prognosis is found in the following cases: in anaplastic astrocytomas with respect to glioblastoma multiforme; in younger patients with respect to the more elderly; the longer the duration of symptoms before diagnosis; and in the event in which surgery has been macroscopically radical. An improvement in treatment outcome is foreseeable with the use of advanced volume definition techniques for radiation therapy. MATERIALS AND METHODS AND RESULTS Our experience with conventional radiation treatment shows therapeutic results in agreement with other institutions. In the overall 134 cases MST was 50 weeks and the 2-year survival rate was 10%. In patients affected by anaplastic astrocytoma MST was 58% and 2-year survival rate was 17%, whereas the figures ...

Three hundred and seventy-eight patients were included in this retrospective study (121 women and 257 men; 71 years median age, with a range of 29–93 years) and subjected to RT-PCR tests for suspicious COVID-19 infection. All patients were subjected to CT examination in order to evaluate the pulmonary disease involvement by COVID-19. CT images were reviewed first by two radiologists who identified COVID-19 typical CT patterns and then reanalyzed by another two radiologists using a CT structured report for COVID-19 diagnosis. Weighted k values were used to evaluate the inter-reader agreement. The median temporal window between RT-PCRs execution and CT scan was zero days with a range of (−9, 11) day...
