This study evaluates the relationship between Positron Emission Tomography (PET)/Computed Tomography (CT) and VATS findings, the result of the first pleural biopsy, and the final diagnosis of malignancy or non-malignancy.Methods: Prospective study of consecutive patients with pleural effusions undergoing PET/CT and VATS from October 2013 to December 2023. The following variables were recorded: PET/CT score (nodular pleural thickening, pleural nodules with standardized uptake value (SUV) > 7.5, lung mass or extra pleural malignancy, mammary lymph node with SUV > 4.5 and cardiomegaly); VATS data (drained volume, visceral and parietal pleural thickening, nodules or masses, septa, plaques, fluid appearance, trapped lung, and suspected diagnosis of the procedure), as well as the histological study of the first pleural biopsy (benign or malignant) and the final diagnosis of benign or malignant pleural effusion. A logistic regression study of the variables was performed.Results: 95.8% of the patients with PET/CT and pleuroscopy not suggestive of malignancy had non-malignant histological findings, while 93.2% of the patients with PET/CT and pleuroscopy suggestive of malignancy had malignant histological findings. PET/CT, pleuroscopy, and the result of the first pleural biopsy showed a significant association with the final diagnosis of pleural effusion.Conclusions: There is a strong association between PET/CT findings, VATS and pleural histology.","PeriodicalId":94197,"journal":{"name":"Revista espanola de medicina nuclear e imagen molecular","volume":" ","pages":"500059"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142305206","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its ability to provide functional and anatomical images simultaneously and its excellent resolution contributes to a more precise and personalised approach in the treatment of osteoarticular diseases such as spondylodiscitis. In addition, it has proven valuable in patients with suspected infection that is complex to diagnose or treat, improving detection in subclinical stages. However, some limitations have been identified, such as difficulty in the differential diagnosis of infection vs. inflammation (as in diabetic foot) or in the interpretation of patients with osteosynthesis materials.

Muscle and adipose tissue characteristics were evaluated, including lumbar (L3) and cervical (C3) muscle areas, psoas major (PM) and sternocleidomastoid muscle (SCM) parameters, and PET parameters for visceral and subcutaneous adipose tissue (SAT). Sarcopenia was determined using CT images, with a threshold for muscle tissue at the L3 vertebral level, and its impact on overall survival (OS) was investigated.Results: Sarcopenia was detected in 48 patients. SULmax in the primary tumor (PT) was significantly higher in sarcopenic patients (SP). The frequency of distant metastasis was higher in SP and OS was significantly lower. In the locally advanced stage, sarcopenia status decreased survival. L3, PM, C3, and SCM muscle areas were highly correlated. Subcutaneous adipose tissue SUVmax was significantly increased in SP and those with distant metastasis. Univariate analysis identified PT SULmax, PT SUVmean, PT TLG, lymph node and distant metastasis, SAT SUVmax, and sarcopenia as poor prognostic factors, while multivariate analysis confirmed BMI, distant metastasis, PT SUVmean, PT TLG as independent predictors of OS.Conclusion: This study demonstrated that sarcopenia, linked to reduced survival, correlates with primary tumor SULmax, distant metastasis, and subcutaneous tissue PET parameters, exerting a notable impact on survival, particularly in locally advanced stages. Attenuation-corrected CT can be used instead of diagnostic CT, and sarcopenia can be diagnosed using not only L3 but also C3 slices.","PeriodicalId":94197,"journal":{"name":"Revista espanola de medicina nuclear e imagen molecular","volume":" ","pages":"500090"},"PeriodicalIF":0.0,"publicationDate":"2024-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142901557","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
