An image-quality CT phantom was scanned with three different 3D X-ray imaging guidance devices in the operating theatre: O-Arm, Loop-X, and Airo TruCT. Default acquisition and reconstruction parameters for lumbar spine procedures were used on each device. The tube current was set to a dose level of around 27 mGy.

- The study aims to evaluate the effectiveness of Photon-Counting CT (PCCT) compared to Dual-Source CT (DSCT) in reducing radiation dosage while improving the quality of chest CT images.
- Tests were conducted on phantoms using both CT technologies at various dose levels, with parameters like noise magnitude and detectability of specific lung lesions assessed to measure performance.
- Results showed that PCCT had significantly lower noise levels and better detectability of lung lesions, with a potential dose reduction of nearly 59% compared to DSCT, indicating PCCT's promise for safer chest imaging in patients.
Article Synopsis
- The study aimed to evaluate how well an AI system can detect bone fractures compared to radiologists, using CT scans as the ultimate benchmark.
- It involved 94 adult patients and found that the AI had a sensitivity of 82% and specificity of 69%, meaning it missed some fractures and misidentified some normal cases.
- The radiologists performed better overall, with a sensitivity of 92% and specificity of 88%, indicating they were more accurate in diagnosing the fractures.
Background: Image-guided percutaneous lung biopsy (PLB) may lead to major complications requiring hospitalization. This study aims to evaluate the rate of major PLB complications and determine a predictive computed tomography (CT) score to define patients requiring hospitalization due to these complications.
Methods: This single-center retrospective study included all PLBs performed from July 2019 to December 2020 in Nimes University Hospital, France.
Purpose: To compare the spectral performance of two different DSCT (DSCT-Pulse and DSCT-Force) on virtual monoenergetic images (VMIs) at low energy levels.
Methods: An image quality phantom was scanned on the two DSCTs at three dose levels: 11/6/1.8 mGy.
