The most commonly utilized PET radionuclide is fluorine-18 ((18)F) because of its convenient half-life and excellent imaging properties. In this review, we present the first analysis of patents issued for radiotracers labeled with fluorine-18 (between 2009 and 2015), and provide perspective on current trends and future directions in PET radiotracer development.

Background Synaptic loss is an important factor in Alzheimer disease (AD); however, blood assays that conveniently and rapidly reflect changes in synaptic density are lacking. Purpose To correlate multiple potential synaptic blood markers with synaptic density measured using F-SynVesT-1, a fluorine 18 (F)-labeled radiotracer, brain PET and to explore the independent associations between these markers and synaptic density. Materials and Methods This prospective study included 50 cognitively unimpaired (mean age, 65.

Background: With the next generation of Human Epidermal Growth Factor Receptor 2 (HER2) -targeting therapies, such as antibody-drug conjugates, showing benefit in "HER2 low" and even "HER2 ultralow" patients, the need for novel methods to quantify HER2 expression accurately becomes even more important for clinical decision making. A HER2 PET/CT imaging assessment could evaluate HER2 positive disease locations while improving patient care, reducing the need for invasive biopsies. A single-domain antibody (sdAb)-based PET tracer could combine the high specificity of sdAbs with short-lived radionuclides such as fluorine-18 (F) and gallium-68 (Ga).

Introduction: Lymphobronchial tuberculosis (LBTB) is a tuberculous lymphadenopathy causing airway compression in young children. While it can occur in older children due to factors such as airway size, wall weakness, and immune reconstitutions, severe airway obstruction is more common in younger children.
Methods: Chest X-rays show airway compression, while bronchoscopy is the gold standard for confirming TB-induced airway compression.
