Journal ArticleDOI
Nonprostatic diseases on PSMA PET imaging: a spectrum of benign and malignant findings
Felipe de Galiza Barbosa,Marcelo Queiroz,Rafael F. Nunes,Larissa B. Costa,Elaine C. Zaniboni,José Flávio Gomes Marin,Giovanni Guido Cerri,Carlos Alberto Buchpiguel +7 more
TL;DR: The overall benefits of endothelial PSMA expression, which is associated with the neovasculature of malignant neoplasms, will be highlighted, stating the potential use of PSMA ligand uptake as a theranostic tool.
Journal ArticleDOI
PET/MRI and PET/CT in advanced gynaecological tumours: initial experience and comparison
Marcelo Queiroz,Rahel A. Kubik-Huch,Nik Hauser,Bianka K. Freiwald-Chilla,Gustav K. von Schulthess,Johannes M. Froehlich,Patrick Veit-Haibach +6 more
TL;DR: PET/MRI is superior to PET/CT for primary tumour delineation and might be the preferred imaging modality for staging cervical and endometrial tumours and whole-body staging for detection and evaluation of extra-abdominal metastases is mandatory.
Journal ArticleDOI
The symmetric eigenvalue complementarity problem
TL;DR: It is shown that the symmetric (EiCP) is equivalent to finding an equilibrium solution of a differentiable optimization problem in a compact set and similar results apply to the Symmetric Generalized Eigenvalue Complementarity Problem (GEiCP).
Journal ArticleDOI
PET/MRI and PET/CT in follow-up of head and neck cancer patients
Marcelo Queiroz,Martin Hüllner,Felix P. Kuhn,G. F. Huber,Christian M Meerwein,Spyros Kollias,Gustav K. von Schulthess,Patrick Veit-Haibach +7 more
TL;DR: CePET/MRI may be superior compared to cePET/CT to specify unclear FDG uptake related to possible tumour recurrence in follow-up of patients after HNC, and gadolinium in PET/MRI did not yield higher diagnostic accuracy, but helped to better define tumour margins in 6.9 % of patients.
Journal ArticleDOI
PET/MR in Cancers of the Head and Neck
TL;DR: Current trends and potential clinical applications of PET/MR in the imaging of head and neck cancers, including clinical protocols, are discussed, and potential benefits of implementing functional MR techniques into hybrid PET/MRI of headand neck cancers are discussed.
