This scanner in combination with in vitro studies and probe-based dynamic measurements provided the tools for early establishment of many Nuclear Medicine centres worldwide (in combination with use of radionuclides for therapy).
We present our initial experience with human clinical studies using 18Ffluorodeoxyglucase (FDG) with this scanner, in comparison to PET-CT.
This scanner operates in 3D mode and has the following reported specifications: 11.5 % energy resolution and a timing resolution of 585 ps.
The feasibility of PET/MRI of the head and upper neck using this scanner type in patients with nasopharyngeal carcinoma was previously demonstrated [ 19].
Between one day and one week before the subjects were due to be scanned, they were trained on the task that they would perform in the scanner; this also allowed us to measure their performance and thus compare task difficulty for the different conditions.
As it required a lot of training for the dogs to remain still in the scanner, this approach is not applicable in a clinical setting.
In a paper just out this month, Steven Brusatte and colleagues announced a new tyrannosaur, Timurlengia euotica, based on the results of work done on this in-house scanner.
Whilst we cannot fully exclude this possibility because we collected no reading measures in the scanner, we believe this explanation is highly unlikely.
Regarding the differences in the scanner performance within this multi-center trial, appropriate scanner calibrations had been performed to keep discrepancies at minimum level.
