Article Title: Impact of patient size on image quality of OSEM3D and BSREM reconstructions in [ 68 Ga]Ga-DOTA-TATE PET/MR
Article Snippet: This is the first study demonstrating the relation between patient size and image quality in OSEM3D and BSREM [ 68 Ga]Ga-DOTA-TATE PET/MR reconstructions, and although the results are in line with digital GE and analogue Siemens PET/CT scanners more validation is needed for generalization of current findings.

Article Title: An electric-field-responsive paramagnetic contrast agent enhances the visualization of epileptic foci in mouse models of drug-resistant epilepsy.

Article Title: Impact of patient size on image quality of OSEM3D and BSREM reconstructions in [ 68 Ga]Ga-DOTA-TATE PET/MR.
Article Snippet: This difference might be caused by differences in patient size and liver biodistribution, differences in weight distribution, digital versus analogue detectors, MR versus CT AC, different OSEM3D TOF + PSF reconstruction algorithms (GE versus Siemens) and parameters (4i28s and voxel size of 2.34 × 2.34 × 2.78 mm versus 3i21s, and voxel size of 4.1 × 4.1 × 4.1 mm) and different post reconstruction filter (7 mm vs 3 mm).

Article Title: Negative Correlation Between 18 F-RGD Uptake via PET and Tumoral PD-L1 Expression in Non-Small Cell Lung Cancer
Article Snippet: The PET images were reconstructed and analyzed using the OSEM−3D IAM software program (IS_v1.4.3 SP1; Siemens Preclinical Solutions, LLC).

Article Title: Adoptive macrophages reverse the immunosuppressive microenvironment in glioblastoma via programmed phenotypic polarization
Article Snippet: .. PET images were reconstructed using a three-dimensional ordered subset expectation. maximization (OSEM3D, two iterations) algorithm followed by a maximum a posteriori algorithm (18 iterations; Siemens). .. Tissues were freeze-sectioned with a thickness of 10 μm, fixed with 4% paraformaldehyde for 20 min, permeabilized with 0.25 % Triton X-100 for 10 min, blocked with 5% BSA and then incubated at 4 °C overnight with the following primary antibodies: rabbit anti-CD34 (1:200, Abcam, ab81289) and rat anti-CD11b (1:100, Invitrogen, 14-0112-82) at 4 °C overnight.

Article Title: Development and bioevaluation of 18 F-labeled bivalent cyclic peptides for PET imaging of αvβ6 integrin overexpression.
Article Snippet: Integrin αvβ6 has emerged as a critical target in cancer diagnostics and therapeutics.. In this study, we developed two bivalent ligands, NOTA-(SDM17)2 and NOTA-(AvB6)2, for positron emission tomography (PET) imaging of αvβ6 integrins.. Surface plasmon resonance (SPR) revealed affinities for NOTA-(SDM17)2 and NOTA-(AvB6)2 with KD values of 2.15 μM and 5.21 μM, respectively.

Article Title: Drinking and Water Handling in the Medaka Intestine: A Possible Role of Claudin-15 in Paracellular Absorption?
Article Snippet: .. CT and SPECT images were co-registered using a transformation matrix and SPECT data was reconstructed using the Siemens MAP3D algorithm (matrix 128 × 128, 0.5 mm pixels, 16 iterations, and 6 subsets). .. RNA isolation was conducted according to the manufacturer’s protocol (TRI Reagent ® ; Sigma Aldrich, St. Lois, MO, USA).

Article Title: Automatic Production and Preliminary PET Imaging of a New Imaging Agent [ 18 F]AlF-FAPT
Article Snippet: .. The three-dimensional ordered subset expected maximum (OSEM3D) algorithm (Siemens, Erlangen, Germany) was used for image reconstruction and conversion into a percentage of injected dose per gram of tissue (% ID/g). .. Data was analyzed by manually drawing the region of interest (ROI) above the tumor, followed by attenuation correction of the coronal image of the main organs on the whole body using the Inevon Research Workplace 4.2 software (Siemens, Erlangen, Germany).
