The following data were systematically assessed: degree of lesion filling, fracture stabilization, cement leakage, adverse events, and pain outcome at 3 months postoperatively, assessed from follow-up consultations using a four-level semi-quantitative scale (worsening pain, stable pain, pain improvement, or complete pain resolution).ResultsA total of 59 extraspinal thoracic bones were treated by cementoplasty during 51 procedures among 43 consecutive patients (27 women [63%] and 16 men [37%]; median age = 60 years). Most lesions were metastases or multiple myeloma lesions. Among patients with available follow-up, pain improvement or complete pain resolution was observed in 29/33 (88%) patients. Cement filling of more than 60% of the lesion volume was achieved in 40/45 (89%) focal lesions. Fracture stabilization was successful in 20/23 (87%) cases. Major cement leakage occurred in 5/56 (9%) treated bones with available postoperative imaging and was asymptomatic in all cases. One infectious complication was recorded.ConclusionCementoplasty of extraspinal thoracic bone lesions appears technically feasible and may represent a valuable palliative option for pain relief with an acceptable safety profile.","PeriodicalId":7143,"journal":{"name":"Acta radiologica","volume":" ","pages":"713-720"},"PeriodicalIF":1.2,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148429560","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}

Radiomics captures relevant quantitative imaging information that maybe useful for this differentiation. We aimed to evaluate the diagnostic performance of CT-based radiomics for the preoperative differentiation of pheochromocytoma from LPA. PubMed, Scopus, Embase, and Web of Science were comprehensively searched from inception through October 13, 2025. Eligible studies applied CT-based radiomics to differentiate pheochromocytoma from LPA. Pooled sensitivity, specificity, likelihood ratios, diagnostic odds ratio, and area under the curve (AUC) were estimated. Statistical heterogeneity was assessed using I2 statistic and subgroup analyses were conducted to find their potential sources. Publication bias was assessed using Deek's funnel plot asymmetry test. After deduplication and thorough screening process, seven studies encompassing 1,272 patients met the inclusion criteria. Six studies were included in the meta-analysis, yielding a pooled sensitivity of 0.92 (95% CI, 0.83-0.97), specificity of 0.89 (95% CI, 0.79-0.94), and AUC of 0.85 (95% CI, 0.81-0.94). Subgroup analyses showed higher sensitivity in studies reporting image preprocessing (0.97 vs 0.83, P < 0.01). No considerable publication bias was detected (P = 0.12). Nomogram models integrating radiomics with clinicoradiological features achieved significantly higher AUCs than radiomics-only models (0.95 vs 0.87, P = 0.004). In conclusion, CT-based radiomics demonstrated high accuracy for distinguishing pheochromocytoma from LPA, with unenhanced CT providing the strongest discrimination. Integration of radiomics with clinicoradiological variables further enhances performance.

Multivariate regression analysis showed that patients in the co-existing HRPs group were more likely to have a higher prevalence of diabetes (OR = 3.92, 95% CI = 1.53-10.04; P = 0.004) and family history of cardiovascular disease (CVD) (OR = 3.37, 95% CI = 1.26-8.98; P = 0.015) compared to the non-HRP group after adjusting for age, sex, high-density lipoprotein (HDL), and smoking. Similarly, patients with co-existing HRPs were more likely to have higher prevalence of diabetes (OR = 2.49, 95% CI = 1.04-5.95; P = 0.040) compared to the single HRP group after adjusting for age, sex, and HDL.ConclusionCo-existing extracranial carotid and intracranial artery HRPs are observed in middle-aged and elderly symptomatic atherosclerotic patients. Diabetes and family history of CVD are independent risk factors for co-existing HRPs.","PeriodicalId":7143,"journal":{"name":"Acta radiologica","volume":" ","pages":"557-567"},"PeriodicalIF":1.2,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147872890","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}

PubMed, Scopus, and Web of Science were searched through 31 March 2025. Studies using histopathologic or cytologic reference standards were included. Pooled estimates of sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy were calculated using random-effects models. Subgroup analyses and meta-regression were performed to explore potential effect modifiers. Studies evaluating contrast-enhanced computed tomography were included in the qualitative synthesis but were not incorporated into the quantitative meta-analysis.ResultsA total of 59 studies were included in the systematic review. Among these, 54 CEUS studies provided sufficient data for quantitative synthesis. CEUS demonstrated pooled sensitivity of 78.6% and specificity of 82.6%, with an overall diagnostic accuracy of 81.6%. Subgroup analyses indicated that examiner experience significantly influenced diagnostic performance, with higher sensitivity observed in studies involving more experienced operators. Meta-regression did not identify statistically significant independent associations between examined covariates and diagnostic outcomes.ConclusionThe available literature indicates that CEUS demonstrates favorable diagnostic performance for differentiating benign from malignant thyroid nodules. Further prospective studies using standardized imaging protocols and reporting frameworks are needed to better define the role of CEUS in thyroid nodule evaluation.","PeriodicalId":7143,"journal":{"name":"Acta radiologica","volume":" ","pages":"636-650"},"PeriodicalIF":1.2,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148203608","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}
