However, with advances in the management of lung cancer, there is a need for a greater amount of tissue for tumor genomic profiling and characterization. Purpose To determine whether the number of core samples obtained with percutaneous CT-guided lung biopsy is associated with postprocedural complications. Materials and Methods This retrospective study included consecutive patients who underwent percutaneous CT-guided coaxial lung core-needle biopsy for suspected primary lung cancer between November 2012 and August 2023 at an academic tertiary referral hospital. Patient data from medical records were collected, including demographics, lesion size and distance from pleura, and number of obtained biopsy samples. Postprocedural complications of pneumothorax, chest tube placement, perilesional hemorrhage, and hemoptysis were recorded. Multivariable logistic regression models were used to assess whether the number of cores was a predictive factor for lung biopsy complications. Results A total of 827 patients (mean age, 70.9 years ± 9.6 [SD]; 474 [57.3%] female patients) were included. The median lesion size was 22 mm (IQR, 15-34 mm), with 517 of 827 (62.5%) patients diagnosed with lung adenocarcinoma. Pneumothorax was noted in 171 of 827 (20.7%) patients, with a chest tube placed in 32 of 827 (3.9%), perilesional hemorrhage in 353 of 827 (42.7%), and hemoptysis in 20 of 827 (2.4%) patients. The median number of samples obtained was four (range, one to 12). Multivariable analysis showed no evidence of an association between the number of core samples obtained and any complications: pneumothorax (coefficient, -0.02; <i>P</i> = .81), chest tube (coefficient, 0.18; <i>P</i> = .26), perilesional hemorrhage (coefficient, -0.03; <i>P</i> = .63), or hemoptysis (coefficient, -0.10; <i>P</i> = .60). Conclusion In patients suspected of having lung cancer who underwent percutaneous CT-guided coaxial lung core biopsy, there was no evidence of an association between the number of core biopsy samples obtained and any postprocedural complications. © RSNA, 2024 See also the editorial by Zuckerman in this issue.</p>","PeriodicalId":20896,"journal":{"name":"Radiology","volume":null,"pages":null},"PeriodicalIF":12.1,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142584103","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}

However, knowledge is limited on imaging features of NMLs at screening US. Purpose To identify features of NMLs at screening US that are suspicious for malignancy based on mammographic findings. Materials and Methods This retrospective, multicenter study included asymptomatic women who underwent screening US between January 2012 and December 2019. Eligible women had NMLs at US, concurrent screening mammography, and record of a final diagnosis. Logistic regression analyses were used to identify factors associated with malignancy. The diagnostic performance of each sonographic feature according to mammographic findings was calculated. A reader study was performed to assess interreader agreement for sonographic features. Results Among 993 NMLs in 993 patients (mean age, 50 years ± 9 [SD]), 914 (92.0%) were benign and 79 (8.0%) were malignant. Mean size was larger for malignant NMLs than for benign NMLs (2.6 cm ± 1.1 vs 1.9 cm ± 0.8; <i>P</i> < .001). In multivariable analysis, associated calcifications (odds ratio [OR], 21.6 [95% CI: 8.0, 58.2]; <i>P</i> < .001), posterior shadowing (OR, 6.9 [95% CI: 2.6, 18.4]; <i>P</i> < .001), segmental distribution (OR, 6.2 [95% CI: 2.7, 14.4]; <i>P</i> < .001), mixed echogenicity (OR, 5.0 [95% CI: 1.8, 14.0]; <i>P</i> < .001), and size (OR, 1.5 [95% CI: 1.1, 2.1]; <i>P</i> = .01) at US were associated with malignancy. Associated calcifications, posterior shadowing, segmental distribution, and mixed echogenicity showed positive predictive values (PPVs) of 44%, 22%, 22.9%, and 16.6%, respectively. Having a negative mammogram was associated with a lower malignancy rate (2.8% vs 28.8%) and lower PPVs for sonographic features (0.7%-10.4% vs 24%-55%) than having a positive mammogram. Interreader agreement for sonographic features was good to excellent (Fleiss κ 95% CI lower bound range, 0.63-0.81). Conclusion Calcifications, posterior shadowing, segmental distribution, and mixed echogenicity associated with NMLs can be considered suspicious features for malignancy at screening US. As malignancy rates and PPVs differ according to mammographic abnormalities, combined assessment is mandatory. © RSNA, 2024 <i>Supplemental material is available for this article.</i> See also the editorial by Grimm in this issue.</p>","PeriodicalId":20896,"journal":{"name":"Radiology","volume":null,"pages":null},"PeriodicalIF":12.1,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142584101","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 the clinicopathologic-radiologic associations and prognostic implications of MRI-assessed intratumoral fat in HCCs. Materials and Methods This retrospective cohort study included consecutive adult patients who underwent resection for solitary HCCs and preoperative contrast-enhanced MRI from two tertiary-care hospitals in East Asia (March 2011 to December 2021) and Western Europe (September 2012 to December 2019). MRI scans were independently evaluated by three radiologists at each hospital. Based on Liver Imaging Reporting and Data System (LI-RADS) version 2018, intratumoral fat was defined as \"fat in mass more than adjacent liver,\" and the homogeneous subtype was defined as intratumoral fat \"in absence of mosaic and nodule-in-nodule architecture.\" Recurrence-free survival (RFS) and overall survival (OS) were estimated using the Kaplan-Meier method and compared using the log-rank test. Cox regression analyses were conducted to identify factors associated with RFS and OS. Results A total of 933 patients were included in the Asian (<i>n</i> = 736; median age, 53 years [IQR, 45-62 years]; 626 male) and European (<i>n</i> = 207; median age, 64 years [IQR, 55-70 years]; 161 male) cohorts. MRI-assessed intratumoral fat was detected in 30% (215 of 726) and 31% (64 of 207) of patients in the Asian and European cohorts, respectively (<i>P</i> = .72). In both cohorts, the steatohepatitic subtype, nonperipheral washout, enhancing capsule, and mosaic architecture were more frequent in tumors with intratumoral fat (<i>P</i> value range, <.001 to .04). Intratumoral fat in general was not associated with RFS or OS in either cohort (<i>P</i> value range, .48-.97). However, in the Asian cohort, homogeneous intratumoral fat was associated with longer RFS (hazard ratio [HR], 0.60; <i>P</i> = .009) and OS (HR, 0.33; <i>P</i> = .008) in multivariable Cox regression analyses. Conclusion MRI-assessed intratumoral fat was more frequent in steatohepatitic HCCs and associated with nonperipheral washout, enhancing capsule, and mosaic architecture. Although intratumoral fat was generally nonprognostic, homogeneous intratumoral fat was associated with longer RFS and OS in the Asian cohort.

Purpose To assess the sex-specific association of LVM measured with cardiac MRI with cardiovascular outcomes in those with a less than 20% 10-year risk of cardiovascular disease (CVD). Materials and Methods A total of 1528 volunteers older than 40 years of age with no history of CVD, a 10-year risk of CVD of less than 20%, and a B-type natriuretic peptide level greater than their sex-specific median underwent cardiac MRI between June 2008 and February 2013 as part of the Tayside Screening for Cardiac Events, or TASCFORCE, prospective study. LVM was indexed to body surface area, and the LVM-to-volume ratio was calculated. Follow-up for cardiovascular events was performed using national electronic health records. Cox proportional hazard models and Kaplan-Meier curves were applied to assess the impact of LVM. Results A total of 1495 participants (mean age, 54.5 years ± 8.3 [SD]; 925 female, 570 male) completed cardiac MRI, with a median follow-up of 10 years (IQR, 3 years). In female participants, LVM was associated with age, blood pressure, smoking status, and cholesterol level, while in male participants, LVM was associated with age and blood pressure. In female participants, the LVM-to-volume ratio was associated with cardiovascular events (hazard ratio [HR], 2.3 [95% CI: 1.1, 4.9] for the highest quartile vs the lowest quartile), while the LVM was not. In male participants, the LVM was associated with cardiovascular events (HR, 3.2 [95% CI: 1.5,7.0] for the highest quartile vs the lowest quartile), while the LVM-to-volume ratio was not.
