Ziel/Aim With continuing technological and radiopharmaceutical progress in PET imaging as well as increased use of PET quantification, the demands on PET Quality Control (QC) are growing. However, actual PET QC guidelines focus on equipment, good practice and reference measurements outside clinical routine but do not include actual QC product inspection, i.e. a systematic validation of each of the resulting PET images. We introduce the term ‘extended PET quality control’ (xQC) for PET QC including fully automated QC Inspection of individual datasets and images. Our aim is Proof of Concept for xQC by an in-depth evaluation of PET data from a recent nationwide survey organized by the Swiss Association for Nuclear Medicine.

Ziel/Aim For multicenter clinical studies, PET/CT and SPECT/CT scanners need to be validated to ensure comparability between diverse scanner types and brands. This validation is usually performed using hollow phantoms filled with radioactive liquids. Recently, 3D printing technology has been introduced for manufacturing of phantoms. However, an approach to directly print radioactive phantoms on a 3D printer does not yet exist. The goal of this work was to develop a method for preparation of radioactive organic liquid resin monomers (“3D printer ink”) and demonstrate successful application of this building material for 3D printing of several test objects.

Im klinischen Alltag wird oft ein Zusammenhang von Tageszeit oder Wetterbedingungen mit dem Eintreffen von Unfallopfern diskutiert. Wir wollten dies konkret an unserem Traumazentrum überprüfen, um aufgrund der Resultate mögliche Ressourcenoptimierungen umsetzen zu können.
