Diagnosing VGI requires a multidisciplinary approach combining clinical, laboratory, and imaging findings. While CTA remains the first-line imaging modality, its limitations in detecting chronic or low-grade infections highlight the value of advanced nuclear medicine techniques, particularly [18F]FDG PET/CT. In this review, we discuss the role of [18F]FDG PET/CT in diagnosing VGI, emphasizing its high sensitivity and negative predictive value, which are critical for ruling out infection. Nevertheless, there are currently no universally accepted criteria for analyzing PET/CT findings in VGI, which poses challenges for consistent interpretation and clinical decision-making. This review aims to provide a comprehensive understanding of FDG PET/CT imaging in the context of VGI by exploring visual grading scales, uptake patterns, and semi-quantitative parameters while highlighting potential pitfalls such as post-surgical inflammation and false-positive results due to graft materials or surgical adhesives. Through a series of illustrative cases, we outline characteristic imaging patterns of infected and non-infected grafts, offering practical guidance for accurate interpretation. Additionally, we discuss the evolving role of FDG PET/CT in assessing treatment response and guiding follow-up in VGI management. This pictorial review seeks to enhance diagnostic accuracy and bridge the gap in standardized PET/CT interpretation criteria, ultimately contributing to improved patient care.","PeriodicalId":49135,"journal":{"name":"the Quarterly Journal of Nuclear Medicine and Molecular Imaging","volume":"69 1","pages":"61-68"},"PeriodicalIF":1.5,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143587775","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}

We aimed to assess interobserver and intraobserver reproducibility for detecting renal cortical defects using [99mTc]Tc-MAG3 for adults and children; identify causes for poor inter- and intraobserver reproducibility and to assess the effect of the kidney to background ratio (KTBR) on reproducibility.Methods: One hundred adult and 200 pediatric renograms were included. The observers reviewed the summed 1-minute posterior images for the first four minutes to detect cortical defects. Interobserver reproducibility between three observers and intra-observer reproducibility for two observers were determined. Agreement was tested using percentage agreement, Krippendorff's reliability coefficient alpha and Cohen's kappa statistic. The association between KTBR and agreement was evaluated.Results: Interobserver agreement on the 1-2 minutes images was 78 (95% CI: 74.8-82.7%) and 79.7 (95% CI: 75.9-83.5%) for left and right kidneys respectively. Intraobserver percentage was 89.7% (95% CI: 86.2-93.1%) for the senior and 80.7% (95% CI: 76.2-85.2%) for the junior observer. In 13.5% (27) of the adult and 4.5% (19) of the pediatric kidneys the difference in image interpretation between the observers would have had a clinical impact. If the KTBR is ≤2, the percentage agreement was between 61.5% and 64.8%. In cases with a KTBR >2, the percentage agreement was between 83.6% and 87.1%.Conclusions: The percentage interobserver agreement was moderate. Disagreement between normal and abnormal cases were infrequent. The interobserver reproducibility was decreased when the KTBR was ≤2.","PeriodicalId":49135,"journal":{"name":"the Quarterly Journal of Nuclear Medicine and Molecular Imaging","volume":" ","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143048430","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}

Magnetic resonance imaging (MRI) and multiphase computed tomography (CT) have been the preferred imaging modalities for diagnosis, staging, and surveillance of patients with these malignancies. The best clinical outcomes depend on the appropriate selection of treatment options from the tools available in neo-adjuvant therapy, surgical resection, locoregional therapy, liver transplantation, and adjuvant therapy. While not a part of the routine diagnostic work-up or follow-up, F-18 fluorodeoxyglucose positron emission tomography (FDG PET/CT) can inform therapeutic decision making and help avoid futile surgeries by detecting unsuspected distant metastases. Additionally, metabolic information obtained with FDG PET/CT has prognostic value, predicting treatment response and survival. In patients with HCC metabolic parameters obtained by FDG PET/CT have been shown to correlate with microvascular invasion and predict recurrence in orthotopic transplant recipients. This article will highlight studies that have evaluated the role of FDG PET/CT in diagnosis, staging and therapeutic response assessment in patients with hepatobiliary cancers.","PeriodicalId":49135,"journal":{"name":"the Quarterly Journal of Nuclear Medicine and Molecular Imaging","volume":"68 4","pages":"245-258"},"PeriodicalIF":1.5,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143025273","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}
