T lymphocytes are key mediators of the adaptive immune response. Inappropriate or imbalanced T-cell responses are underlying factors in cancer progression, allergy, and other immune disorders. Monitoring the spatiotemporal dynamics of T cells and their functional status has the potential to provide unique biologic insights into health and disease. Noninvasive PET imaging represents an ideal whole-body modality for achieving this goal. With the appropriate PET imaging probes, T-cell dynamics can be monitored in vivo with high specificity and sensitivity. Herein, we provide a comprehensive overview of the applications of this state-of-the-art T-cell PET imaging toolbox and the potential it has to improve the clinical management of cancer immunotherapy and T-cell-driven diseases. We also discuss future directions and prospects for clinical translation.

Purpose: The study explores the role of multimodal imaging techniques, such as [F]F-PSMA-1007 PET/CT and multiparametric MRI (mpMRI), in predicting the ISUP (International Society of Urological Pathology) grading of prostate cancer. The goal is to enhance diagnostic accuracy and improve clinical decision-making by integrating these advanced imaging modalities with clinical variables. In particular, the study investigates the application of few-shot learning to address the challenge of limited data in prostate cancer imaging, which is often a common issue in medical research.

Background: Oncolytic viruses (OVs) are promising immunotherapeutics to treat immunologically cold tumors. However, research on the mechanism of action of OVs in humans and clinically relevant biomarkers is still sparse. To induce strong T-cell responses against solid tumors, TILT-123 (Ad5/3-E2F-d24-hTNFa-IRES-hIL2, igrelimogene litadenorepvec) was developed.

A young man in his 30s presented to us with multiple episodes of syncope and exertional dyspnoea for the last 2 weeks. He was diagnosed with squamous cell carcinoma of the lower one-third of the oesophagus in 2021 for which he was treated with neoadjuvant chemoradiotherapy, followed by McKeown oesophagectomy. At 2-year follow-up, he had developed a soft tissue swelling in the scalp, which was diagnosed as a tumour recurrence and radiotherapy was initiated.

Purpose: To investigate the prognostic value of post-chemoradiotherapy 2-[F]FDG PET/CT in locally advanced nasopharyngeal carcinoma (LANPC) and develop an accurate prognostic model based on the 2-[F]FDG PET/CT results.
Methods: 900 LANPC patients who underwent pretreatment and post-chemoradiotherapy 2-[F]FDG PET/CT from May 2014 to August 2022 were included in the study. We divided the patients into two distinct cohorts for the purpose of our study: a training cohort comprising 506 individuals, included from May 2008 to April 2020, and a validation cohort consisting of 394 individuals, included from May 2020 to August 2022.

Tuberculosis (TB), caused by Mycobacterium TB, is the most significant infectious cause of mortality across the globe. While TB disease can prey on immunocompetent individuals, it is more likely to occur in immunocompromised individuals. Immune-mediated inflammatory diseases (IMIDs) are a group of diseases (rheumatoid arthritis, inflammatory bowel disease, ankylosing spondylitis, psoriasis, hidradenitis suppurative, autoimmune blistering diseases, and others) where there may be a need for systemic immunosuppression to control the disease manifestations, treat symptoms and improve long term outcomes.
