Article Abstract
Background: The 2023 European Society of Cardiology (ESC) guidelines for the management of infective endocarditis (IE) highlighted the essential role of multimodal imaging in the diagnostic algorithm of IE and its complications.
Methods: We hereby report a case series of IE in which the diagnosis was confirmed or excluded by the use of multimodal imaging during the period between January 2024 and July 2024 at the Infectious Diseases Clinic, Perugia Hospital, Italy.
Results: Six patients were retrospectively included. Prosthetic valve endocarditis (PVE) was suspected in four patients and native valve endocarditis (NVE) in two cases. In patients with prosthetic valves, 18F FDG-PET/CT was performed, except in one case (P1) where cardiac CTA was performed for suspicion of perigraft aneurysm. Patients underwent transesophageal echocardiography (TOE), which was diagnostic in two cases and inconclusive in the remaining cases. In case of inconclusive TOE, the use of multimodal imaging added a major criterion and allowed us to consider (from 'rejected' to 'possible') or confirm (from 'possible' to 'definite') the diagnosis of EI based on the 2023 Duke-ESC Criteria. In one case (P6), it was possible to exclude the diagnosis. For patients with diagnostic TOE, 18F FDG-PET/CT allowed for the enhancement of diagnostic accuracy, identifying the site of valve involvement and the extension of the infection to the device (cases P3 and P5, respectively).
Conclusions: In clinical practice, the use of cardiac CTA and/or 18F FDG-PET/CT based on the latest ESC guidelines demonstrated a significant impact on the diagnosis and therapeutic management of IE.

Purpose: The present study aimed to develop a noninvasive predictive framework that integrates clinical data, conventional radiomics, habitat imaging, and deep learning for the preoperative stratification of MGMT gene promoter methylation in glioma.
Materials And Methods: This retrospective study included 410 patients from the University of California, San Francisco, USA, and 102 patients from our hospital. Seven models were constructed using preoperative contrast-enhanced T1-weighted MRI with gadobenate dimeglumine as the contrast agent.
Leveraging GPT-4o for Automated Extraction and Categorization of CAD-RADS Features From Free-Text Coronary CT Angiography Reports: Diagnostic Study.

Background: Despite the Coronary Artery Reporting and Data System (CAD-RADS) providing a standardized approach, radiologists continue to favor free-text reports. This preference creates significant challenges for data extraction and analysis in longitudinal studies, potentially limiting large-scale research and quality assessment initiatives.
Objective: To evaluate the ability of the generative pre-trained transformer (GPT)-4o model to convert real-world coronary computed tomography angiography (CCTA) free-text reports into structured data and automatically identify CAD-RADS categories and P categories.

Over three decades, statistical parametric mapping has transformed neuroimaging from descriptive mapping to causal inference, placing generative models at the core of causal explanations for brain function. It inspired to a large degree The Virtual Brain, which builds subject-specific digital twins from multimodal data, enabling brain simulations and exploration. Both frameworks converge at parameter estimation, where model and data meet, providing the mathematical manifestation of cause-effect in pathophysiology.

Background: Ovarian cancer (OC) remains the most lethal gynecological malignancy, largely due to its late-stage diagnosis and nonspecific early symptoms. Advances in biomarker identification and machine learning offer promising avenues for improving early detection and prognosis. This review evaluates the role of biomarker-driven ML models in enhancing the early detection, risk stratification, and treatment planning of OC.
