{"title":"Hemoperitoneum Quantification in Non-contrast CT: Evaluating Feasibility with the Novel HUVAO Segmentation Algorithm","authors":"Rahul Bhagawati, Suman Hazarika, C. N. Gupta, S. Chanda","doi":"10.1055/s-0043-1778672","DOIUrl":"https://doi.org/10.1055/s-0043-1778672","url":null,"abstract":"Abstract Background  Injuries involving substantial bleeding, frequently encountered in victims of road traffic accidents, pose a significant risk to mortality. For abdominal trauma cases, accurately assessing internal bleeding and hematomas becomes crucial. Detecting hemoperitoneum, which indicates both blood loss and organ damage in the abdominal cavity, requires precise evaluation. Timely diagnosis and quantification of hemoperitoneum following road accidents are crucial during the critical golden hour, enabling prioritized medical intervention and potentially saving lives while enhancing overall patient care. However, achieving precise hemoperitoneum quantification in abdominal trauma faces challenges due to the intricate nature of overlapping Hounsfield unit (HU) regions. Methods  In this feasibility study, we sought to assess the efficacy of the novel HUVAO (Hounsfield Unit-based Volume quantification of Asymmetrical Objects) segmentation algorithm for quantifying hemoperitoneum in thoracoabdominal non-contrast computed tomography (CT) images. Using 28 retrospective non-contrast CT scans of thoracoabdominal regions from trauma patients, we analyzed crucial imaging data without necessitating additional scans or contrast-enhanced procedures. The study aimed to compare HUVAO against classical algorithms and visual estimations by trained radiologists for hemoperitoneum segmentation in thoracoabdominal non-contrast CT images. Results  Our findings revealed that although the technical feasibility of employing HUVAO and other segmentation algorithms for hemoperitoneum quantification is evident, the outcomes derived from these algorithms display notable discrepancies. Conclusion  In assessing technical feasibility, we introduced the HUVAO segmentation algorithm for hemoperitoneum quantification, comparing its performance against classical segmentation algorithms and visual estimations from trained radiologists. While our results affirm the technical feasibility of HUVAO for this purpose, the observed variations underscore the task's inherent complexity. This emphasizes the limitations of relying solely on HU-based detection, advocating for integration with clinical data. This insight urges exploration of advanced techniques to boost accuracy and elevate patient care standards.","PeriodicalId":52666,"journal":{"name":"Journal of Gastrointestinal and Abdominal Radiology","volume":"48 14","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139528139","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}

Methods  In this cross-sectional and retrospective record-based study, radiological (NCCT and MRCP) data were collected retrospectively for a period of 3 years (June 2018–August 2020) from 52 patients. The results were compared to the final diagnosis on endoscopic retrograde cholangiopancreatography (ERCP) findings (gold standard). The data collected were analyzed by measuring the sensitivity, specificity, positive predictive value, negative predictive value, diagnostic accuracy, and p -value for NCCT, MRCP, and integrated NCCT plus MRCP at different cutoff points. Subsequently, a receiver operating characteristic (ROC) curve was plotted to analyze different thresholds for NCCT, MRCP, and integrated NCCT plus MRCP. Results  The most common pathologies identified were biliary dilations (18.4%), common bile duct (CBD) calculi (13.6%), and biliary strictures (12.0%). Overall, MRCP provided a higher percentage of correct diagnoses (81.6%) compared to CT (56.0%). Integrating NCCT with MRCP showed a significant increase in sensitivities and specificities when compared to NCCT or MRCP alone. Integrated NCCT plus MRCP showed excellent performance with an area under the curve (AUC) of ROC analysis of 0.937. Conclusion  Our study showed that integrating NCCT and MRCP can prove to be an excellent tool in establishing a detailed diagnosis of PB disorders, better than either NCCT or MRCP alone. Due to the concurrent nature of PB disorders, it may be worth considering integrating NCCT and MRCP, given that there is an absence of contraindications to either modality.","PeriodicalId":52666,"journal":{"name":"Journal of Gastrointestinal and Abdominal Radiology","volume":"30 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75067836","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}

The diagnosis of sarcopenia is based on documentation of two of the three criteria: low muscle mass, low muscle strength, and low physical performance. Imaging-based assessment of muscle mass is preferred in both clinical and research settings. Anthropometry for the evaluation of muscle mass is prone to errors and is not recommended in the clinical setting. There is a lack of literature on the radiological assessment of sarcopenia and its association with prognosis in hepatobiliary, pancreatic, and gastrointestinal diseases.

The incidence of HCC has been rising due to lifestyle diseases such as obesity, diabetes, non-alcoholic fatty liver disease (NAFLD), and alcoholic liver disease (ALD), as well as viral hepatitis infections. Various locoregional therapies (LRTs) are used to treat HCC, including thermal ablation, transarterial therapies, stereotactic body radiotherapy (SBRT), and transarterial radioembolization (TARE). Traditional response evaluation criteria like WHO and RECIST, which rely on size-based measurements, may not accurately assess treatment response to LRTs. To address this limitation, modified response evaluation criteria for solid tumors (mRECIST) and the LI-RADS treatment response algorithm (LR-TRA) have been developed. mRECIST assesses patient-level response, while LR-TRA provides lesion-level response assessment specifically for HCC treated with LRTs. This article discusses the imaging protocols for diagnosing HCC and the imaging appearances of treated lesions after different LRTs. It explains the criteria for categorizing treatment response, such as LR-TR viable, LR-TR non-viable, and LR-TR equivocal. It also highlights the challenges and future directions in response assessment, including the incorporation of ancillary findings, the assessment of patients receiving a combination of locoregional and systemic therapies, and the potential use of biomarkers like serum AFP, AFP-L3, and PIVKA-II. In conclusion, locoregional therapies have expanded the treatment options for HCC, and accurate response assessment is crucial for optimizing patient management. mRECIST and LR-TRA provide valuable tools for evaluating treatment response, and future updates are expected to address specific challenges and incorporate newer approaches like iRECIST and quantitative imaging assessment. Additionally, the use of biomarkers may complement imaging-based response assessment in the future.","PeriodicalId":52666,"journal":{"name":"Journal of Gastrointestinal and Abdominal Radiology","volume":"27 1","pages":"202 - 211"},"PeriodicalIF":0.0,"publicationDate":"2023-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81031390","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}
