Purpose To identify prognostic factors based on the imaging features of SNs among patients with pathologically confirmed SNs in the same lobe. Materials and Methods This retrospective study included patients with pT2b-pT3 NSCLC who underwent lobectomy or pneumonectomy between January 2010 and December 2021. Radiologic features of the SNs were evaluated. Recurrence-free survival (RFS) and overall survival (OS) were evaluated with Cox proportional hazards regression. Results A total of 1107 patients were evaluated (mean age, 64.8 years ± 9.8 [SD]; 766 male; 498 with pT2b; 141 with SNs; 468 with pT3-other descriptors). In patients with SNs, subsolid SNs were an independent negative prognostic factor for both RFS (hazard ratio [HR], 0.26 [95% CI: 0.12, 0.57]; <i>P</i> = .001) and OS (HR, 0.11 [95% CI: 0.04, 0.32]; <i>P</i> < .001). The number of SNs was an independent positive prognostic factor for RFS (HR, 2.40 [95% CI: 1.24, 4.64]; <i>P</i> = .009). In patients with solid SNs, a nonregional location was the only prognostic factor for shorter OS (HR, 1.92 [95% CI: 1.04, 3.56]; <i>P</i> = .04). No difference was identified between patients with subsolid SNs and those with pT2b tumors for RFS or OS (<i>P</i> > .99). Patients with subsolid SNs had better survival than those with solid SNs (<i>P</i> < .001 for RFS and OS) or pT3-other descriptor tumors (<i>P</i> = .002 for RFS; <i>P</i> < .001 for OS). No survival difference was detected between patients with solid SNs and those with pT3-other descriptor tumors (<i>P</i> > .99). Conclusion In patients with surgically resected NSCLC and pathologic SNs in the same lobe, the presence of ground-glass opacity was associated with outcome. Only subsolid SNs were associated with higher survival rates compared with pT3-other descriptor tumors. © RSNA, 2025 <i>Supplemental material is available for this article.</i> See also the editorial by Goo in this issue.</p>","PeriodicalId":20896,"journal":{"name":"Radiology","volume":"316 1","pages":"e241492"},"PeriodicalIF":12.1,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144691372","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 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}

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}
