manual methodology has not been reported for functional imaging. We explored validation of using automation to delineate regions of interest on positron emission tomography (PET) scans. The purpose of this study was to ascertain improvements in image processing time and reproducibility of a semi-...
The comprehensive diagnostic capabilities offered by TB-PET, though invaluable, also come with risks of information overload for clinicians tasked with interpreting these complex scans. Traditionally, results have been derived through either visual assessment or labour-intensive manual segmentation, approaches...
The Centiloid (CL) scaling was developed to provide standardized amyloid-PET data on a universal unbounded 0 (mean gray matter signal in healthy young adults) to 100 (mean signal in patients with typical AD) scale, regardless of the radiotracer used [13]. To our knowledge, the CL scale ...
(FDG-PET) for detection of lymph node metastases from prostate cancer is notoriously low.2Several other radio pharm aceuticals have been developed to characterize aspects of tumor metabolism apart from glycolysis, offering an alternative to18F-FDG in...
CNS MPO and CNS PET MPO also predicted that reducing the lipophilicity would increase the likelihood of a successful CNS drug/PET radiotracer, respectively. However, two radiotracers were explored with lower lipophilicities, [18F]OXD-2188 and [18F]OXD-2189, and neither showed improved brain ...
Insensitivity to micrometastases may be improved by increasing scanner resolution as well as implementation of new, more specific radioactive tracers. There are some technical limitations to image fusion in combined PET/CT. Limitations are based on differences in respiration state between the CT and ...
The name, dose and route of administration of regulated nonradioactive drugs and agents should also be stated. The type of PET/CT system should be specified, but specific equipment information is optional. A description of the procedure should include the time the patient was examined or the ...
In short, several studies have shown the relevance of FDG imaging in evaluating the response to induction chemotherapy and concomitant radiochemotherapy, both during and after the end of treatment. PET performs well for assessing the response to targeted therapy such as tyrosine kinase inhibitors. How...
