OBJECTIVE. The purpose of this article is to characterize the appearance on CT of e-cigarette or vaping product use-associated lung injury (EVALI) in a cohort with histopathologic evidence of this disorder. MATERIALS AND METHODS. ⋯ Of the eight patients with ground-glass opacity centrilobular nodules resembling HP at CT, none showed HP at histopathologic examination. CONCLUSION. EVALI manifests at CT as ALI with multifocal ground-glass opacity, often with organizing consolidation, and a small centrilobular nodular pattern resembling HP.

Soft Tissue Sarcoma: Preoperative MRI-Based Radiomics and Machine Learning May Be Accurate Predictors of Histopathologic Grade.
OBJECTIVE. The purpose of this study was to assess the value of radiomics features for differentiating soft tissue sarcomas (STSs) of different histopathologic grades. MATERIALS AND METHODS. ⋯ This creates an urgent need to construct an accurate preoperative approach to grading STS. This radiomics study revealed the optimal machine learning approaches for differentiating STS grades. This capability can enhance the precision of preoperative diagnosis.
