Summary: PET imaging using O-(2-[F-18]fluoroethyl)-L-tyrosine (FET) as a tracer has become essential for diagnosing brain tumors, with increasing demand seen for differentiating tumor progress and treatment-related changes. Referring physicians rate FET PET highly for diagnosing recurrent gliomas and brain metastases.

Summary: Legumain is overexpressed in several cancers and serves as an important biomarker for cancer diagnosis. In this study, a novel radioactive tracer [F-18]SF-AAN was designed and synthesized for positron emission tomography (PET) imaging, targeting legumain. The tracer showed specificity in detecting legumain activity in vitro and in vivo, making it a promising tool for the diagnosis of legumain-related diseases.

Summary: This study aimed to reassess the clinical significance of standardized uptake values (SUVs) in nasopharyngeal carcinoma (NPC) on F-18-fluorodeoxyglucose (F-18-FDG) positron-emission tomography (PET). The results showed that high SUVs were associated with cancer recurrence, and the SUVmax-NTR ratio was identified as a potential prognostic factor.

Summary: This case report describes the characteristics of 18F-FDG PET-CT imaging in a dog with an abdominal gossypiboma, which has not been reported in the veterinary literature before. A 13-year-old, spayed, female mixed breed dog underwent mastectomy and ovariohysterectomy and was referred for evaluation of metastasis after surgery. F-18-deoxy-2-D-glucose positron emission tomography/computed tomography (18F-FDG PET-CT) was performed and a soft-tissue mass was observed in the abdominal cavity.

Summary: Glutamine metabolism-related tracer (2S,4S)-4-[F-18]FEBGln has the potential to visualize various tumors through PET imaging, with good tumor retention and contrast. It shows different retention capabilities in different tumor models. The tracer has potential in accurately diagnosing lung cancer and glioma, but cannot accurately determine prostate cancer.

Summary: PET/CT with F-18-2-fluoro-2-deoxyglucose (F-18-FDG) is a promising modality for diagnosing and monitoring treatment response and evaluating prognosis in non-small cell lung cancer (NSCLC) patients. Semiquantitative metabolic parameters measured by PET/CT, such as SUVmax, MTV, and TLG, can predict EGFR mutation status, monitor TKI treatment response, and assess outcome in NSCLC patients.

Summary: This study examined the impact of pretreatment and posttreatment PET/CT imaging on radiation therapy for biliary-tract-carcinomas, pancreatic-ductal-adenocarcinomas, and adenoidcystic-carcinomas. The results showed that pretreatment [Ga-68]FAPI-PET/CT enhanced radiation treatment planning, and the combination of [Ga-68]FAPI and [F-18]FDG imaging improved treatment response assessment.

Summary: This study aimed to investigate the feasibility of predicting progression-free survival (PFS) in breast cancer patients using pretreatment F-18-fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) radiomics signature and clinical parameters. The study found that the integrated clinical-radiomics (ICR) model, which combined clinical parameters and preoperative FDG PET/CT imaging, was able to independently predict PFS in breast cancer patients, and was superior to the clinical model alone and rad-score alone.

Summary: This study aimed to investigate the association between multiple biological factors and fluciclovine PET uptake in human glioblastoma, and found that fluciclovine PET uptake was significantly correlated with the level of the amino acid transporter ASCT2 in tumor cells, suggesting that fluciclovine PET may be useful for assessing amino acid metabolism in brain tumors.

Summary: The heterogeneous uptake of both F-18 FDG and C-11 methionine on PET/CT in renal cell carcinomas is associated with higher grades of cancer. The metabolic tumour volume on F-18 FDG PET/CT but not C-11 methionine PET/CT is significant in predicting advanced-stage renal cell carcinoma. These metabolic features derived from PET/CT imaging may aid in the development of new drugs targeting glucose and amino acid metabolic pathways.

Summary: The study revealed a reorganization of functional connectome communities in Alzheimer's disease patients, resulting in lower overall efficiency and higher tau pathology burden in nodes tending to leave communities. This suggests a correlation between local tau pathology in AD and fundamental changes in basic organizational principles of the human connectome.

Summary: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease with neuroinflammation playing a key role in its pathogenesis. A treatment study using RD2RD2 in a transgenic mouse model of ALS showed reduction of astrocytes and microglia activation, rescue of neurons, and slowed disease progression, making RD2RD2 a potential therapeutic candidate against ALS.

Summary: In individuals with subjective cognitive decline (SCD), memory complaints are associated with sub-clinical depression and executive functions rather than memory performance. Additionally, memory complaints in SCD are correlated with higher gray matter density in specific brain regions. The study did not find evidence of early neurodegeneration in SCD, but identified sub-clinical depression as a potential underlying factor for subjective cognitive complaints.

Summary: This study used structural MRI and amino acid PET in conjunction with brain atlases and elastic registration techniques to investigate the impact of treatment-related brain damage on cognitive functioning in well-functioning WHO Grade III/IV glioma patients. The results showed that T2/FLAIR hyperintensities caused by radiation therapy significantly impaired cognitive performance, especially affecting the left hemisphere functional nodes and fiber tracts, which were highly correlated with verbal episodic memory dysfunction.

Summary: Advanced MRI methods and PET using radiolabelled amino acids provide valuable additional information for brain tumour diagnostics. While the hybrid PET/MRI has allowed for the convergence of these methods, simultaneous imaging has limited relevance in clinical neuro-oncology. A multimodal approach that combines PET and MRI shows promising improvement in the diagnosis of cerebral gliomas.

Summary: Changes in F-18-FET PET parameters were found to be helpful for early identification of responders to adjuvant TMZ therapy, predicting prolonged progression-free survival (PFS) and overall survival (OS). These changes were independent of other strong prognostic factors, suggesting their potential clinical utility in glioma patients.

Summary: A linearized model for dynamic PET scans of F-18-FET TACs was derived and validated in this study, showing high agreement with measured TACs and small parameter uncertainties. The model demonstrated good diagnostic performance in discriminating between IDH wildtype and IDH mutant gliomas in adult patients. Voxel-wise fitting within a short computation time and comparable classification accuracy to linear fits based on average TAC values were achievable.
