2-stage AI process helps grade severity of COVID on x-rays
A new two-stage process for using artificial intelligence (AI) to grade the severity of COVID-19 infection on chest x-rays could work better than existing AI-based algorithms, say researchers who described their process in a paper published July 27 in Scientific Reports.

7 hidden reasons people quit their jobs -- and how to prevent it
PHOENIX - There are seven hidden reasons why most employees quit their jobs, a trend that in radiology is exacerbating the shortage of radiologic technologists (RTs). But in a July 10 presentation at AHRA 2022, Maureen Firth offered tips for improving the recruiting and retention of RTs.

PCCT has higher safety profile than EID-CT for lung imaging

Subgroup analysis based on lesion size on PCCT images. The red outlined areas highlight the magnified images of lesions. (A-C) PCCT images in a 62-year-old woman with a body mass index (BMI) of 23.6, calculated as weight in kilograms divided by height in meters squared, who was diagnosed with adenocarcinoma. A lesion with a long diameter of 25 mm was identified in the right lower lobe on axial images acquired during the venous phase. For lesions less than or equal to 30 mm, decreasing section thickness improved boundary sharpness and contrast between the necrotic area and enhanced tissue, with optimal visualization at 0.4 mm. (D-F) PCCT images in a 66-year-old man with a BMI of 24.2 who was diagnosed with adenocarcinoma, revealing a lesion with a long diameter of 52 mm in the right lower lobe. For lesions greater than 30 mm, a section thickness of 1 mm demonstrated better contrast and clarity at the boundary of the necrotic area compared with 0.4 mm. This observation supported the selection of an appropriate section thickness for accurate quantification of necrotic regions within the lesion.
