Histogram analysis enhances diagnostic accuracy by evaluating spatial heterogeneity.PurposeTo assess the performance of histogram analysis models utilizing relaxation maps from SyMRI in diagnosing csPCa.Material and MethodsA total of 124 men with a clinical suspicion of csPCa were enrolled prospectively between April 2018 and December 2019. From 124 patients, 224 ROIs were analyzed, including 97 csPCa lesions, 11 insignificant PCa, 59 non-cancerous peripheral zone (PZ) lesions, and 57 benign prostatic hyperplasia. The lesions were randomly divided into a training group and a validation group, in a ratio of 7:3. Histogram analysis models were constructed using SyMRI relaxation maps, diffusion-weighted imaging (DWI), apparent diffusion coefficient (ADC), and their combination. We compared these with mean-value-based models using the same modalities. The diagnostic accuracy of these models in distinguishing csPCa from clinically insignificant disease (CIS) was evaluated.ResultsHistogram analysis models outperformed mean-value-based models in both training and validation groups. SyMRI-based histogram analysis models demonstrated diagnostic effectiveness comparable to DWI and ADC models. The combined model achieved the highest area under the curve values in the PZ (0.898; 95% confidence interval [CI]=0.763-0.999) and transition zone (TZ) (0.944; 95% CI=0.874-0.999). In the TZ, the combined model significantly outperformed the Prostate Imaging Reporting and Data System (P = 0.019).ConclusionHistogram analysis of SyMRI relaxation maps is a valuable tool for differentiating csPCa from CIS. Combining SyMRI with DWI and ADC further improved diagnostic accuracy.","PeriodicalId":7143,"journal":{"name":"Acta radiologica","volume":" ","pages":"2841851251349488"},"PeriodicalIF":1.1,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144315750","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The patients were stratified into high-risk and low-risk groups using both the conventional rFSRP and a novel approach incorporating ultrasonic plaque features.

A notable disparity in stroke-free survival rate was observed between high-risk and low-risk groups when classified using the combined criteria of rFSRP and ultrasonic features (P <0.001). The net reclassification improvement formula, accounting for reclassification accuracy, indicated that 11.2% of patients were more precisely classified under the combined criteria.

Dual-energy X-ray absorptiometry (DXA) is the gold standard for osteoporosis diagnosis; however, its limitations have driven research into alternative methods.PurposeTo explore the diagnostic potential of cervical MRI-derived vertebral bone quality (VBQ) scores in predicting osteoporosis, in comparison to lumbar vertebra measurements.Material and MethodsThis retrospective study included patients who had DXA scans between 2020 and 2023 and underwent cervical MRI within 6 months. A total of 213 patients were classified into normal (n = 72), osteopenia (n = 82), and osteoporosis (n = 59) groups based on their DXA T-scores. T1-weighted MRI images were used to measure vertebral body signal intensity (SI) and cerebrospinal fluid (CSF) SI, which were then used to calculate VBQ scores. Both cervical and lumbar VBQ scores were compared to DXA results to evaluate diagnostic efficacy.ResultsCervical VBQ scores, particularly the C4:posterior fossa CSF SI ratio, demonstrated significant correlations with DXA T-scores (P = 1.7 × 10-5). The study found that the C4:posterior fossa CSF SI ratio had a high diagnostic accuracy (AUC = 0.81) for distinguishing between normal bone density and osteopenia/osteoporosis. Furthermore, cervical VBQ scores showed stronger correlations with bone density than lumbar scores, suggesting that the cervical spine may serve as a more effective diagnostic region.ConclusionCervical MRI-derived VBQ scores, especially the C4:posterior fossa CSF SI ratio, offer a promising non-invasive tool for osteoporosis diagnosis.

The aim of this review was to investigate the current evidence of interventions for supporting informed decision-making on attendance to BCS by immigrant women. An integrative review was conducted by searching online databases (Medline, PubMed, PsycInfo, CINAHL, Scopus). A quality appraisal of the articles was performed using Joanna Briggs Institute quality appraisal checklists and mixed method appraisal tool. Data were extracted and synthesized using narrative analysis. A total of 25 articles were included in the study. Interventional strategies for supporting informed decision-making on attendance to BCS by immigrants were home visits, personal navigation service support, education sessions, and media-led information. In summary, to ensure the effective adoption of interventions for immigrants, it is imperative to consider cultural and linguistic tailored interventions, involve family members, especially husbands, offer free BCS and navigation services to those with limited financial resources, and, most importantly, uphold women's autonomy in their decision to participate in BCS.","PeriodicalId":7143,"journal":{"name":"Acta radiologica","volume":" ","pages":"2841851251344475"},"PeriodicalIF":1.1,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144207358","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated for each observer and observation.ResultsIn the study group, the triangular structure was disrupted in 18 knees for the first observer's first observation, and 17 knees for the second observation; for the second observer, it was 15 knees and 17 knees, respectively. In the control group, the numbers were 2, 6, 1, and 3, respectively. Mean Cohen's κ statistic was 0.81 (range=0.73-0.87). Sensitivity, specificity, PPV, and NPV were 66.7%-75%, 87.5%-97.9%, 72.7%-94.4%, and 84%-88.5%. respectively.ConclusionDisruption of MPT is an additional finding that may help the diagnosis of chronic patellofemoral instability.","PeriodicalId":7143,"journal":{"name":"Acta radiologica","volume":" ","pages":"2841851251346704"},"PeriodicalIF":1.1,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144198052","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
