1. Acquisition only. The acquired dynamic data is stored in a list file.
  2. Radiopharmaceuticals may not be approved by ministers of health in all regions. 177Lu-PSMA is currently not an FDA approved tracer.
  3. NM/CT 870 DR with MEGP collimator.
  4. Average of 12 detectors.
  5. Compared to NM/CT 870 DR and NM/CT 870 CZT, StarGuide’s planar sensitivity was measured for each of its 12 detectors and adapted from NEMA NU 1-2018. NM/CT 870 DR used LEHR/LEHRS collimators and NM/CT 870 CZT used the WEHR collimator for both planar and SPECT measurements.
  6. Compared to NM/CT 870 DR and NM/CT 870 CZT. StarGuide SPECT reconstruction with scatter used the system’s factory NEMA NU 1-2018 resolution protocol which uses the same method (BSREM with Clarity 3D) as its clinical bone protocol. NM/CT 870 DR and NM/CT 870 CZT SPECT reconstruction used Evolution for Bone (OSEM). NM/CT 870 DR used LEHR/LEHRS collimators and NM/CT 870 CZT used the WEHR collimator.
  7. As demonstrated in phantom testing using a model observer.
