Background: After stereotactic body radiation therapy (SBRT) for lung tumors, follow-up CT scans remain a pitfall. The early detection of local relapse is essential to propose a new treatment. We aim to create a local recurrence predictive score using pre- and post-therapeutic imaging criteria and test it on a validation cohort.

- F-FDG PET/CT is now included in the ESC 2015 guidelines for diagnosing infective endocarditis, but its effectiveness in native valve endocarditis (NVE) is not fully understood.
- A study involving 75 patients identified that while F-FDG PET/CT had low sensitivity (17.5%) for diagnosing NVE, it maintained high specificity (100%) and was effective for detecting embolic events.
- The research also revealed a new diagnostic feature of diffuse splenic uptake seen in over half of the patients with NVE, suggesting its potential utility in clinical practice.
Background: In FDG-PET, SUV images are hampered by large potential biases. Our aim was to develop an alternative method (ParaPET) to generate 3D kinetic parametric FDG-PET images easy to perform in clinical oncology.
Methods: The key points of our method are the use of a new error model of PET measurement extracted from a late dynamic PET acquisition of 15 min, centered over the lesion and an image-derived input function (IDIF).
Introduction: F-FDOPA illustrates the properties of uptake and storage of catecholamines in pheochromocytomas (PHEOs). Until now, the relationship between F-FDOPA quantitative parameters and a PHEO secretory profile has not been specifically evaluated.
Materials And Methods: Fifty-six patients (56% females, median age: 47.
