Summary: Using animal models to study the mechanisms of aging in the brain is crucial for developing interventions for aging-related brain disorders. In this study, young and aged rats were examined using positron emission tomography to build brain metabolic networks. It was found that aged rats showed similar aging-related alterations in brain metabolism as humans, making them a suitable model for studying aging and potential therapies.

Summary: Conventional MRI has limitations in assessing disease progression and treatment-related changes in malignant brain tumors. 18F-fluoroethyltyrosine (18F-FET) perfusion PET/MRI was implemented to overcome these limitations. The hybrid 18F-FET perfusion PET/MRI showed high accuracy and reliability for difficult diagnostic cases, and positively impacted clinical management.

Summary: Neuropathic pain is associated with significant reorganization in the brain, as evidenced by changes in metabolic brain networks following brachial plexus injury. Despite overall network stability, specific brain regions showed increased nodal properties, indicating a compensatory response to the injury. Strengthened connectivity between key brain regions highlights the importance of certain areas in the network's adaptation to neuropathic pain.

Summary: This study aimed to compare the diagnostic accuracy of 18F-FDG PET/CT and PET/MRI for the diagnosis of distant metastases in patients with malignant tumors. The study found that 18F-FDG PET/MRI had higher sensitivity and AUC value than PET/CT for detecting distant metastases overall, while in breast cancer patients and lung cancer patients, the accuracies of PET/MRI and PET/CT differed.

Summary: This study aims to assess the correlation between SUV-derived indices and volumetric uptake parameters in 18F-FDOPA PET/CT for primary brain tumors. The results demonstrate that volumetric uptake parameters are easier to assess in primary brain tumors with higher SUV max and SUV max ratios, highlighting the emerging role of volumetric parameters in data interpretation.

Summary: The aim of this study was to evaluate the utility of dual-time point [F-18]FDG PET/CT imaging in the diagnosis of indeterminate soft tissue tumors (STTs). The results showed that DTPI has a high specificity in identifying malignant STT tumors and outperforms the diagnostic accuracy of standard PET/CT.

Summary: FAPI PET/CT showed superior imaging performance in detecting R/M GISTs, especially for liver metastases. The uptake of FAPI reflected the level of FAP expression and was independent of tumor size, degree of enhancement, gene mutation type, and targeted therapy.

Summary: This study explores the cerebral metabolic patterns of cerebral palsy patients without structural abnormalities using brain magnetic resonance imaging (MRI) scans and F-18-fluoro-deoxyglucose positron emission tomography (F-18-FDG PET) imaging. The findings suggest asymmetric metabolic reductions and negative correlations with GMFCS scores. The differential cortical glucose metabolism by F-18-FDG PET could help distinguish between different CP diagnoses that are not detected by MRI.

Summary: This retrospective study analyzed the diagnostic utility and impact on clinical management of [F-18]FET-PET in 21 pediatric and adolescent patients with CNS tumors. The results showed that [F-18]FET-PET had an impact on the treatment decisions of 14 patients, including avoidance of invasive surgery or biopsy, biopsy guidance, change of treatment, and confirmation of diagnosis.

Summary: This study evaluated the metabolic parameters of F-18-FDG PET/CT and found that high MTV and TLG values were prognostic factors for overall survival in patients with malignant melanoma. These findings could potentially guide clinicians in decision making and identifying patients with a poorer prognosis.

Summary: This study revealed a negative correlation between brain glucose metabolism and age, with females showing a more significant metabolic reduction in the posterior-cingulate cortices, especially in post-menopausal age. The results suggested the pons as the most appropriate normalization reference.

Summary: The study found that F-18-FBY is well tolerated by healthy volunteers with rapid clearance and excretion profile. In glioma patients, F-18-FBY uptake increased with tumor grade and showed positive correlations with LAT-1 expression and Ki-67 labeling index. The PET tracer has potential in assessing LAT-1 expression and guiding boron neutron capture therapy in gliomas.

Summary: Metal fluoride nanocrystals can induce controlled release of fluorophores and drug molecules in various biological systems through desilylation cleavage chemistry. The use of biocompatible PEG-coated CaF2 nanocrystals has shown efficient release of functional molecules. This strategy has also been applied to prodrug activation with remarkable anticancer effects and minimal side effects, empowering metal fluoride nanocrystals for further biological applications.

Summary: Targeted alpha-therapy (TAT) is a promising treatment for cancer with excellent efficacy. However, the supply of alpha-emitters for TAT is limited, and Pb-212 extracted from natural thorium has the potential to meet this demand. Researchers have developed a practical method to isolate Pb-212 from natural thorium, which could be an important breakthrough in the field.

Summary: The study successfully conjugated two fatty acids (lauric acid and palmitic acid) to FAPI-04 to form two albumin-binding FAPI radiopharmaceuticals, FAPI-C12 and FAPI-C16. They exhibited high binding affinity to FAP, stable in circulation, and significantly increased tumor uptake and retention, showing potential for CAF-targeted radionuclide therapy.

Summary: This study developed and evaluated two albumin-binder conjugated FAPI radiopharmaceuticals (TEFAPI-06 and TEFAPI-07) to address the issue of fast clearance and insufficient tumor retention. The results showed significantly improved tumor accumulation and retention compared to the original FAPI tracer, and these radiopharmaceuticals demonstrated remarkable growth inhibition of PDX tumors with negligible side effects.

Summary: This study investigated the relationship between FBY PET- and MRI-defined tumor volumes in contrast-enhanced diffuse gliomas and circumscribed brain tumors. The results showed that the MRI-defined tumor volume was smaller than the FBY-defined tumor volume and mostly contained within it. There was a significant difference in the DICE score between circumscribed tumors and diffuse tumors, but for regions with increased FBY metabolism and no MRI contrast enhancement, both types of tumors showed similar SUVmean values.
