The acquired emission data were reconstructed using iterative reconstruction (two iterations, eight subsets), with attenuation, random, and scatter correction, and a post-reconstruction Gaussian filter of 7 mm was applied.
The acquired data were reconstructed using iterative reconstruction ordered subset expectation maximization (OSEM) 3-D FLASH (8 subsets and 10 iterations).
CT data were reconstructed using an iterative reconstruction algorithm (iDose, Philips Healthcare, Cleveland, OH, USA) with iDose level 4 and a slice thickness of 3 mm.
So, if the same raw data were reconstructed using a different reconstruction method, the resulting images might be of better or worse quality, but they would have the same NECpatient.
Whole-body list mode PET data were reconstructed using the offline sorting and reconstruction programs included in the e7 toolbox (Siemens Healthineers, Erlangen, Germany; version VA20).
The acquired three-dimensional emission data were reconstructed using a maximum a posterior (MAP) reconstruction method with attenuation correction.
Data were reconstructed using a time-of-flight (TOF) reconstruction algorithm (blob-based OSEM TOF) using standard reconstruction settings, as these cannot easily be modified by the user.
The gated LEHR projection data were reconstructed using ordered subset expectation maximization (OSEM -based Flash3D iterative recOSEM -based (Siemens Healthineers, Erlangen, Germany).
The attenuation-corrected PET data were reconstructed using a standardized ordered-subset expectation maximization (OSEM) iterative reconstruction with two iterations and eight subsets and a 5-mm Gaussian filter.
The acquired data were reconstructed using the ordered subset expectation maximization (OSEM) FLASH 3-D iterative reconstruction method.
The tomographic data were reconstructed using the filtered back projection algorithm.
