A 57-year-old man with newly diagnosed with prostate cancer was admitted to our department for 68 Ga-prostate-specific membrane antigen PET/CT imaging. The patient, who was asymptomatic at the time of imaging, had increased diffuse 68 Ga-prostate-specific membrane antigen uptake in the trachea on PET/CT. No ground-glass density suggestive of pneumonia in both lungs was observed. The patient, whose symptoms developed 2 days after PET/CT imaging, was diagnosed with coronavirus disease 2019 by real-time polymerase chain reaction.

Here, we describe the case of a 74-year-old male patient with a high-risk prostate carcinoma who underwent positron-emission tomography/computed tomography (PET/CT) with [Ga]Ga-prostate-specific membrane antigen ([Ga]Ga-PSMA-11) for staging. [Ga]Ga-PSMA-11 PET/CT detected an extensive area of increased tracer uptake at the prostatic level, involving both lobes. Additionally, a rounded lesion approximately 4 cm in diameter was identified in the celiac region adjacent to the stomach, exhibiting moderate tracer uptake.

Introduction: We sought to develop a model that predicts lymph node invasion (LNI) in patients with intermediate- and high-risk prostate cancer incorporating preoperative clinical and Ga-prostate-specific membrane antigen positron emission tomography/computed tomography (PSMA PET/CT) parameters.
Methods: A cohort of 413 consecutive patients diagnosed with prostate cancer who underwent Ga- PSMA PET/CT prior to radical prostatectomy from 2015-2020 was used to develop and validate the model. The cohort was split into a learning (70%) and a validation group (30%).
Second primary malignancies are being increasingly detected in the setting of thyroid cancer, because of adoption of the advanced imaging modalities including PET/CT. Herein, we present a patient of papillary thyroid carcinoma who initially underwent total thyroidectomy with bilateral neck dissection followed by 131 I radioactive iodine therapy. A prostatic lesion was incidentally detected on 18 F-FDG PET/CT scan, which was intensely 18 F-FDG avid and also showed intense focal 68 Ga-prostate-specific membrane antigen (PSMA) uptake on 68 Ga-PSMA-11 PET/CT scan.

Objective: In this study, we retrospectively analyzed the imaging characteristics of dual-tracer Ga-prostate specific membrane antigen (PSMA) and F-flurodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) in metastatic prostate cancer (mPCa) patients. We analyzed the uptake modes of the dual tracers, explored clinical pathological parameters affecting the F-FDG uptake in the lesions, and evaluated their prognostic implications for prostate specific antigen progression-free survival (PSA-PFS).
Methods: A total of 41 mPCa patients who underwent dual-tracer PET/CT (Ga-PSMA and F-FDG) scans between September 2021 and January 2024 were retrospectively enrolled.
