Background Various limitations have impacted research evaluating reader agreement for Liver Imaging Reporting and Data System (LI-RADS). Purpose To assess reader agreement of LI-RADS in an international multicenter multireader setting using scrollable images. Materials and Methods This retrospective study used deidentified clinical multiphase CT and MRI and reports with at least one untreated observation from six institutions and three countries; only qualifying examinations were submitted. Examination dates were October 2017 to August 2018 at the coordinating center. One untreated observation per examination was randomly selected using observation identifiers, and its clinically assigned features were extracted from the report. The corresponding LI-RADS version 2018 category was computed as a rescored clinical read. Each examination was randomly assigned to two of 43 research readers who independently scored the observation. Agreement for an ordinal modified four-category LI-RADS scale (LR-1, definitely benign; LR-2, probably benign; LR-3, intermediate probability of malignancy; LR-4, probably hepatocellular carcinoma [HCC]; LR-5, definitely HCC; LR-M, probably malignant but not HCC specific; and LR-TIV, tumor in vein) was computed using intraclass correlation coefficients (ICCs). Agreement was also computed for dichotomized malignancy (LR-4, LR-5, LR-M, and LR-TIV), LR-5, and LR-M. Agreement was compared between research-versus-research reads and research-versus-clinical reads. Results The study population consisted of 484 patients (mean age, 62 years ± 10 [SD]; 156 women; 93 CT examinations, 391 MRI examinations). ICCs for ordinal LI-RADS, dichotomized malignancy, LR-5, and LR-M were 0.68 (95% CI: 0.61, 0.73), 0.63 (95% CI: 0.55, 0.70), 0.58 (95% CI: 0.50, 0.66), and 0.46 (95% CI: 0.31, 0.61) respectively. Research-versus-research reader agreement was higher than research-versus-clinical agreement for modified four-category LI-RADS (ICC, 0.68 vs 0.62, respectively; P = .03) and for dichotomized malignancy (ICC, 0.63 vs 0.53, respectively; P = .005), but not for LR-5 (P = .14) or LR-M (P = .94). Conclusion There was moderate agreement for LI-RADS version 2018 overall. For some comparisons, research-versus-research reader agreement was higher than research-versus-clinical reader agreement, indicating differences between the clinical and research environments that warrant further study. © RSNA, 2023 Supplemental material is available for this article.

PurposeTo compare the diagnostic performance of restriction spectrum imaging (RSI), with that of conventional multi-parametric (MP) magnetic resonance imaging (MRI) for prostate cancer (PCa) detection in a blinded reader-based format.MethodsThree readers independently evaluated 100 patients (67 with proven PCa) who underwent MP-MRI and RSI within 6 months of systematic biopsy (N = 67; 23 with targeting performed) or prostatectomy (N = 33). Imaging was performed at 3 Tesla using a phased-array coil. Readers used a five-point scale estimating the likelihood of PCa present in each prostate sextant. Evaluation was performed in two separate sessions, first using conventional MP-MRI alone then immediately with MP-MRI and RSI in the same session. Four weeks later, another scoring session used RSI and T2-weighted imaging (T2WI) without conventional diffusion-weighted or dynamic contrast-enhanced imaging. Reader interpretations were then compared to prostatectomy data or biopsy results. Receiver operating characteristic curves were performed, with area under the curve (AUC) used to compare across groups.ResultsMP-MRI with RSI achieved higher AUCs compared to MP-MRI alone for identifying high-grade (Gleason score greater than or equal to 4 + 3=7) PCa (0.78 vs. 0.70 at the sextant level; P

The article discusses Polish sociologist Zygmunt Bauman's life and legacy, it highlights the reluctance to reveal personal details. It reports that Bauman's theories of solid modernity, postmodernity, and liquid modernity explore external forces shaping society, including bureaucratic rationalization and moral indifference. It emphasizes Bauman's evolving understanding of culture, shifting from a Marxist-Leninist perspective to recognizing its role in reducing ambivalence and human agency.

Aspiration has come to play a central role in the British government's approach to educational underachievement. This article revisits research conducted in the 1970s by Paul Corrigan and Paul Willis to examine the impact of neo-liberalism on the school life of young teenagers. The behaviours of working-class children as described by Corrigan and Willis have become increasingly regarded as problematical by policymakers and school leaders. This article discusses the impact of the measures to enhance 'student aspiration' by using quality assurance measures such as benchmarking. The article explores how teenagers now live much more abject and precarious lives than the teenagers who Willis and Corrigan investigated. The conclusion reached is that, in an education context, abjection is imposed on those people who do not fit into the regulatory ideal of achievement via aspiration. The mechanisms that help to bring about this precarious life are identified with reference to Foucault, Kristeva, Agamben and Butler. Educational research into leadership, school improvement and school effectiveness is said to have been complicit in the facilitation of neo-liberal practice into school life, and effective schools are schools that are effective in achieving neo-liberal objectives.

In his liquid-turn writings, Zygmunt Bauman has come to identify liquid modernity as a period of interregnum. Education has a central role to play within the contemporary interregnum by opening up a new public sphere for dialogue. However, the processes of liquefaction manifest themselves in conditions that severely limit a person's ability to exercise their human agency. Bauman provides no indication of how the educators can escape the processes that limit agency, nor does he explain how educators can combat the seductive consumerism that students need to overcome before they can engage in a reconstruction of the public sphere.
