N-alkylaminoferrocene-based (NAAF) prodrugs are activated in the presence of reactive oxygen species (ROS), based on which these target cancer cells (high ROS) and do not affect normal (low ROS). To gain some insights into their mode action vivo, we have investigated biodistribution 18F-labelled NAAF tumor-bearing mice by positron emission tomography (PET). Due to short half-life 18F, experimen...

objective(s): use of a positron emission tomography (pet)/single-photonemission computed tomography (spect) system facilitates the simultaneousacquisition of images with fluorine-18 fluorodeoxyglucose (18f-fdg) andtechnetium (99mtc)-tetrofosmin. however, 18f has a short half-life, and 511kev compton-scattered photons are detected in the 99mtc energy window.therefore, in this study, we aimed to ...

Bladder Cancer (BCa) is the most common malignancy arising from the urinary tract. One of the mainstays of diagnosis, staging, and therapeutic decision-making for BCa is accurate and appropriate imaging. The ability to identify metastatic disease preoperatively is of utmost importance in determining treatment. Advances in standard cross sectional imaging techniques like Computed Tomography (CT)...

UNLABELLED Chemotherapy is currently the treatment of choice for patients with high-risk metastatic breast cancer. Clinical response is determined after several cycles of chemotherapy by changes in tumor size as assessed by conventional imaging procedures including CT, MRI, plain film radiography, or ultrasound. The aim of this study was to evaluate the use of sequential 18F-FDG PET to predict ...

PURPOSE To investigate the prognostic value of preoperative intratumoral 18F-FDG uptake heterogeneity (IFH) derived from positron emission tomography (PET)/computed tomography (CT) in patients with endometrioid endometrial cancer. METHODS We retrospectively evaluated clinicopathological data from patients with pathologically proven endometrioid endometrial cancer who had undergone 18F-FDG PET...

A simple, straightforward and efficient method for the synthesis of [18F]CF4 and [18F]SF6 based on an ion beam-induced isotopic exchange reaction is presented. Positron emission tomography ventilation studies in rodents using [18F]CF4 showed a uniform distribution of the radiofluorinated gas within the lungs and rapid elimination after discontinuation of the administration.

Background The neuroinflammatory response to morphine exposure modulates its antinociceptive effects, tolerance, and dependence. Positron emission tomography radioligands for translocator protein-18kDa such as [18F]DPA-714 are noninvasive biomarkers of glial activation, a hallmark of neuroinflammation. Methods [18F]DPA-714 positron emission tomography imaging was performed in 5 baboons at bas...

Incidental 18F-fluorodeoxyglucose (18F-FDG) uptake in the prostate is often experienced in clinical practice; however, it is difficult to determine whether incidental uptake is indicative of a malignancy or benign state based on the maximum standardized uptake value (SUVmax). In the present study, we investigated the clinical significance of incidental prostate uptake by 18F-FDG positron emissi...

Within the last decade, several folate-based radiopharmaceuticals for Single Photon Emission Computed Tomography (SPECT) and Positron Emission Tomography (PET) have been evaluated; however, there is still a lack of suitable 18F-folates for clinical PET imaging. Herein, we report the synthesis and evaluation of two novel 18F-folates employing strain-promoted and copper-catalyzed click chemistry....
