Diagnostic Performance of Simultaneous [18F]-FDG PET/MR for Assessing Endoscopically Active Inflammation in Patients with Ulcerative Colitis: A Prospective Study Open
Background: To investigate the diagnostic performance of simultaneous 18F-fluoro-deoxyglucose ([18F]-FDG) PET/MR enterography in assessing and grading endoscopically active inflammation in patients with ulcerative colitis. Methods: 50 pati…

Assessment of Ileocolonic Inflammation in Crohn’s Disease: Which Surrogate Marker Is Better—MaRIA, Clermont, or PET/MR Index? Initial Results of a Feasibility Trial Open
Our objective was to define an 18F-FDG PET/MR enterography index as a hybrid surrogate marker for active ileocolonic inflammation in Crohn’s disease (CD) and assess its diagnostic performance in comparison to validated MR indices (MR index…

<sup>68</sup>Ga-DOTATOC PET/CT in Patients with Iodine- and <sup>18</sup>F-FDG–Negative Differentiated Thyroid Carcinoma and Elevated Serum Thyroglobulin Open
68Ga-DOTATOC PET/CT should be considered in the case of negative 18F-FDG PET/CT in radioiodine-negative DTC patients with elevated and rising thyroglobulin. Imaging with 68Ga-DOTATOC appears promising espec…

Impact of Point-Spread Function Modeling on PET Image Quality in Integrated PET/MR Hybrid Imaging Open
In whole-body PET/MR hybrid imaging, PSF-based PET reconstructions can improve activity recovery and image noise, especially at lateral positions of the PET field of view. This has been demonstrated quantitatively in phantom experiments as…
