Nuclear Medicine Imaging in Tumor Diagnostics Using FAPI-PET/CT

Stephanie Göller, Anna-Maria Spektor, Marcus Stockinger, Justus Kaufmann et autres

Unlike FDG, FAPI tracers target fibroblast activation protein inhibitor (FAPI), highly expressed in the tumor microenvironment. This allows better differentiation between viable tumor and post-therapeutic changes, that is, fibrosis or inflammation. Here, a 39-year-old man with a malignant peripheral nerve sheath tumor …

Clinical implications and diagnostic utility of 68 Gallium FAPI PET CT in patients with testicular germ cell tumors: The prospective phase Ib FAPI-TEST study.

Maximilian Peter Brandt, Niklas Roelz, Štefan Porubský, L Frey et autres

5127 Background: The fibroblast activation protein (FAP) is overexpressed in tumor tissue by cancer associated fibroblasts and radiopharmaceuticals can bind to this target. Recently, the 68 Ga-FAPI PET has emerged as a novel imaging modality for optimized differentiation between benign and malignant …

68Ga-FAPI-PET/CT in extra-cervical CUP: Head-to-Head Comparison of 68Ga-FAPI-46 with 18F-FDG in 13 patients

Anna-Maria Spektor, Sergio Armando Zapata Bonilla, Philipp Mildenberger, Anton Kilburg et autres

Abstract Purpose Oncological treatment in a substantial portion of patients with cancer of unknown primary (CUP) remains challenging due to limitations of conventional imaging and positron emission tomography/computed tomography with 18 Fluor-fluorodeoxyglucose ( 18 F-FDG-PET/CT). In head and neck-like CUP (HNCUP), several …

Parametric mapping of dynamic 68Ga FAPI-46-PET data of 42 patients with pancreatic lesions

Anna-Maria Spektor, Isabelle von Goetze, Hans-Georg Buchholz, Ulrike Heger et autres

PURPOSE: Differential diagnoses of primary pancreatic lesions include pancreatic ductal adenocarcinomas (PDAC) and inflammatory lesions of the pancreas (ILP). Post-pancreatic surgery, differentiation of postoperative reactive tissue (PRT) and PDAC-recurrence challenges oncological imaging. Static 68Ga-FAPI-PET/CT uptake is increased in all of these lesions …

68Ga-FAPI PET/CT for non-invasive characterization and activity assessment of ulcerative colitis and Crohn´s disease

Josefin Debus, Isabelle von Götze, Johannes Brandt, Robert Ehehalt et autres

Abstract Purpose Inflammatory Bowel Diseases (IBD) comprise ulcerative colitis (UC) and Crohn’s disease (CD). Management of IBD requires assessment of disease activity, severity, extent and complications. Here, we describe the signal behavior of both CD and UC in 68 Gallium- fibroblast activation …

68Gallium-labelled fibroblast activation protein inhibitor uptake in joints: a single-center cohort analysis of 268 patients

Anna-Maria Spektor, Antonia van Genabith, Jorge Hoppner, Leon Walkenbach et autres

Abstract Objective Musculoskeletal diseases such as osteoarthritis (OA) are leading causes of pain, physical inactivity and disability worldwide. Synovial fibroblasts (SFs) expressing fibroblast activation protein (FAP) are crucial for OA progression. Positron emission tomography (PET) with 68 Gallium-labelled FAP-inhibitors ( 68 Ga-FAPI) …

Digital Biopsy and Network Analysis of Dynamic [ 68 Ga]Ga-FAPI-46 Data in Patients with Malignant and Benign Pancreatic Lesions

Manuel Röhrich, Frederik M. Glatting, Anna-Maria Spektor, Hans‐Georg Buchholz et autres

The pathologies pancreatic ductal adenocarcinomas, inflammatory lesions of the pancreas, postpancreatectomy reactive tissue, and recurrent pancreatic ductal adenocarcinomas all express fibroblast activation protein and are hardly distinguishable by static PET using [68Ga]Ga-labeled fibroblast activation protein inhibitors (FAPIs) combined with CT. Dynamic imaging …
