Article Synopsis
- The study aimed to evaluate and compare radiation doses from brain examinations conducted on older and newer CT scanners, focusing on metrics like the computed tomography dose volume index (CTDI) and dose length product (DLP).
- Using data from January 2020 to mid-2021 and analyzing it with Microsoft Excel, the study incorporated statistical methods to assess the effectiveness of the scans while comparing them to established reference values.
- Results indicated that the newer CT scanners produced approximately 30% lower radiation doses compared to older models, highlighting their potential for safer imaging practices.
Objectives: Lung ultrasound reduces the number of chest X-rays after thoracic surgery and thus the radiation. COVID-19 pandemic has accelerated research in lung ultrasound artifacts detection using artificial intelligence. This study evaluates the accuracy of artificial intelligence in A-lines detection in thoracic surgery patients using a novel hybrid solution that combines convolutional neural networks and analytical approach and compares it with a radiology resident and radiology experts' results.

We also evaluated the extent and severity of COVID-19-associated lung changes in relation to PE.
Methods: The total number of 1,698 patients with CTPA included in the study were divided into 2 groups according to their COVID-19 status and each group was divided into 2 subgroups based on their PE status.
Objectives: The current retrospective study focused on evaluation of the relationship between pulmonary embolism during COVID-19 pandemic and demographic, presenting symptoms, comorbidities and laboratory results in patients who underwent CT angiography of the pulmonary arteries.
Methods: The study enrolled all adult patients with suspected acute pulmonary embolism (PE) who underwent computed tomography pulmonary angiography (CTPA) between March 1, 2020, and April 30, 2022, during the SARS-CoV-2 pandemic. 1698 CTPAs were reviewed and various data were collected.
