Purpose To investigate associations between pre-existing plaque compositions and new components within the same subclinical carotid plaque and describe the evolution of plaque compositions, focusing on age- and sex-specific patterns. Materials and Methods This prospective study, embedded within the Rotterdam Study, included participants aged 45 years and over with carotid intima-media thickness greater than 2.5 mm and two MRI examinations at baseline (October 2007 to November 2012) and 6-year follow-up (August 2014 to May 2017). All MRI examinations were performed at the Rotterdam Study research center on the same scanner. Plaque components, including calcification, intraplaque hemorrhage (IPH), and lipid-rich necrotic core, were evaluated by designated radiologists. To examine associations of baseline plaque compositions (combinations of individual components) with incident new components, generalized estimating equations were used to model longitudinal cluster data, calculate odds ratios (ORs) and 95% CIs, and adjust for confounders. Age-specific probabilities of changes in plaque compositions during follow-up were calculated, and a 30-year evolution of plaque compositions was simulated based on the Chapman-Kolmogorov equation. Results In total, 802 participants were included (mean age, 68.5 years ± 8.2 [SD]; 461 male), with only 2.9% of plaques (43 of 1460) having carotid stenosis exceeding 50%. Carotid plaques with calcification were independently associated with a higher incidence of IPH (adjusted OR, 2.00 [95% CI: 1.26, 3.16]; <i>P</i> = .003). In the simulated plaque evolution, multicomponent plaques represented 10% at age 55 years and increased to over 50% after age 70 years. Compared with women, men were more likely to have plaques with no component or a single component evolve to multicomponent plaques with IPH (men, 21% [116 of 558]; women, 13% [61 of 468]; <i>P</i> < .001). Conclusion Subclinical carotid plaques with pre-existing calcification are more likely to evolve into IPH than calcification-free plaques. Most subclinical carotid plaques progressed to multicomponent plaques in the simulated 30-year continuous plaque evolution, and men are more likely to develop multicomponent plaques with IPH. © RSNA, 2025 <i>Supplemental material is available for this article.</i></p>","PeriodicalId":20896,"journal":{"name":"Radiology","volume":"315 3","pages":"e242248"},"PeriodicalIF":12.1,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144209338","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Purpose To assess the false-negative rate (FNR) of AI mammogram evaluation according to molecular subtype and to investigate the features of and reasons for AI-missed cancers. Materials and Methods This retrospective study identified consecutive patients diagnosed with breast cancer between January 2014 and December 2020. Commercial AI software was used to read the mammograms, and abnormality score (AS) was acquired. AI-missed cancers were defined as those for which AI did not identify a precise location matching the reference standard. The FNR was calculated by counting AI-missed cancers according to molecular subtype (hormone receptor-positive [luminal] vs human epidermal growth factor receptor 2 [HER2]-enriched vs triple-negative). Three blinded radiologists classified AI-missed cancers as either actionable or under threshold, and reasons for misses were determined through nonblinded reviews. Features were compared according to AI detection with the χ² test. Results A total of 1082 consecutive women diagnosed with 1097 cancers (mean age, 54.3 years ± 11 [SD]) were included. AI missed 14% (154 of 1097) of cancers. The FNR was lowest in the HER2-enriched subtype (9% [36 of 398] in the HER2-enriched subtype, 17.2% [106 of 616] in the luminal subtype, and 14.5% [12 of 83] in the triple-negative subtype; <i>P</i> = .001). Compared with AI-detected cancers, AI-missed cancers were associated with younger age, a tumor size less than or equal to 2 cm, a lower histologic grade, fewer lymph node metastases, more Breast Imaging Reporting and Data System category 4 findings, lower Ki-67 expression, and nonmammary zone locations (all, <i>P</i> < .05). In blinded reviews, 61.7% (95 of 154) of AI-missed cancers were actionable; the reasons for misses were dense breasts (<i>n</i> = 56), nonmammary zone locations (<i>n</i> = 22), architectural distortions (<i>n</i> = 12), and amorphous microcalcifications (<i>n</i> = 5). Conclusion To reduce AI-missed cancers on mammograms, attention should be given to luminal cancer, dense breasts, nonmammary zone locations, architectural distortions, and amorphous calcifications.

This article explores recent advances aiming to address these issues, with a focus on compact MRI scanners, portable low-field-strength MRI systems, and high-performance gradient inserts. Compact MRI scanners, specifically those at field strengths ranging from 0.5 to 7 T, in contrast to their whole-body counterparts, improve gradient performance and simplify installation. These compact scanners are typically fixed systems designed for cost reduction, space saving, and easy siting while also requiring much less cryogen yet supporting the use of high-performance gradients. Portable low-field-strength MRI systems (<0.5 T) provide flexible and cost-effective on-site imaging solutions. These portable systems are designed for mobility and increased accessibility, albeit with some quality trade-offs. All these compact scanners and portable systems have smaller physical footprints than conventional scanners due to reduced magnet size and bore width. Many are designed mainly for brain imaging. High-performance gradient inserts enhance existing MRI systems by providing superior spatial resolution or imaging speed, crucial for advanced neuroimaging. These innovations collectively promise to make MRI more accessible or versatile, transforming radiology practices across diverse clinical settings.</p>","PeriodicalId":20896,"journal":{"name":"Radiology","volume":"315 3","pages":"e241904"},"PeriodicalIF":12.1,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12207646/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144258902","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Purpose To determine the cumulative impacts of multifaceted technology-enabled interventions aimed at optimizing RAI on RAI rate, actionability, and resolution over an 8-year period. Materials and Methods In this retrospective cohort study, conducted from January 2015 to December 2022, radiology reports from two tertiary hospitals (study site and control site) were analyzed. A series of quality improvement interventions, including radiologist education, electronic communication tools for tracking RAIs, and performance reports, were implemented at the study site but not at the control site. The RAI rate trend over time was compared between the sites using linear regression. Mixed-effects logistic regression was performed to assess the intervention impact on the RAI rate. RAI actionability and resolution were compared between the sites using the Fisher exact test. <i>P</i> values were corrected using the Bonferroni method. Results Among 7 502 521 total radiology reports (1 323 459 patients) (study site, 3 608 977 reports and 660 051 patients; control site, 3 893 544 reports and 690 115 patients), the RAI rate of the study site decreased by 44%, from 10% (8202 of 81 586) to 5.6% (8972 of 159 599), but remained unchanged at the control site, at 10.9% (8757 of 80 030) vs 11% (16 978 of 153 711) (regression coefficient, -0.09; 95% CI: -0.1, -0.09; <i>P</i> < .001). RAI rates declined with each successive intervention at the study site (<i>P</i> < .001), with regression coefficients decreasing progressively from -0.12 (95% CI: -0.14, -0.10) for the initial intervention to -0.81 (95% CI: -0.83, -0.78) for the final intervention. Recommendation actionability at the study site increased 7.6-fold (from 5.6% [19 of 340] to 42.3% [144 of 340]; <i>P</i> < .001) but remained unchanged at the control site (from 15.0% [51 of 340] to 13.8% [47 of 340]; <i>P</i> = .73). Actionable RAIs were more frequently resolved at the study site than at the control site (84.7% [122 of 144] vs 59.6% [28 of 47]; <i>P</i> < .001).
