This paper introduces an innovative risk assessment tool, a semi-quantitative risk determination (SQRD) method designed to address risk on the operational and organizational level with a distinct patient safety perspective. Quality risk management (ICH Q9) is a systematic process for the assessment, control, communication and review of risks to the quality of the drug (medicinal) product across the product lifecycle. SQRD is a systematic data driven risk assessment tool. It is of practical significance to have a risk assessment tool that directly links to patient safety attributes. The SQRD methodology has five distinctive steps that are customized to address patient impact and non-patient impact quality attributes. The target was to develop and utilize an advanced risk assessment tool that is reliable, robust, objective and data-driven. SQRD can be applied to batch production, continuous process, or a hybrid of the two, and at any stage of the product lifecycle such as early development, pilot formulation development, process validation or commercial manufacturing. The output of SQRD can help in shaping and optimizing the product control strategy. The exercise enables systematic mitigation of the identified risks. The proposed semi-quantitative risk determination (SQRD) tool systematically evaluates data and scientifically establishes reliable, robust and efficient risk assessments.

Based on this consideration, we evaluate scientific literature describing settle plates and active air sampler monitoring effectiveness. A contamination control strategy should be implemented by pharma manufacturers, especially aseptic productions, to assess the effectiveness of environmental monitoring and demonstrate the process is under statistical control. It is of key importance for microbiological monitoring data to correlate as best as possible with total particle monitoring data so each batch release is reliably supported.

Radiomic features capture tissue and lesion characteristics such as heterogeneity and shape, and may, alone or in combination with demographic, histological, genomic or proteomic data, be used for clinical problem-solving. The goal of this CE article is to provide an introduction to the field, covering the basic radiomics workflowfeature calculation and selection, dimensionality reduction, and data processing using tools such as machine learning. Potential clinical applications in nuclear medicine that include prediction of treatment response and survival based on PET radiomic features will be discussed. Current limitations of radiomics, including its sensitivity to image acquisition parameter variations, and common pitfalls such as "overfitting", will also be covered.

Data-driven gating (DDG) using signals derived from PET raw data are promising alternatives to gating approaches requiring additional hardware. However, continuous bed motion (CBM) scans require dedicated DDG approaches for axially-extended PET, compared to DDG for conventional step-and-shoot scans. In this study, a CBM-capable DDG algorithm was investigated in a clinical cohort, comparing it to hardware-based gating using gated and fully motion-corrected reconstructions. Methods 56 patients with suspected malignancies in thorax or abdomen underwent whole-body 18F-FDG CBM-PET/CT imaging using DDG and hardware-based respiratory gating (pressure-sensitive belt gating, BG). Correlation analyses were performed on both gating signals. Besides static reconstructions, BG and DDG were used for optimally-gated PET (BG-OG, DDG-OG) and fully motion-corrected PET (elastic motion correction; BGmpensation of CBM-PET acquisitions outperforms static reconstructions, delivering qualities comparable to hardware-based approaches. The new algorithm may be a valuable alternative for CBM-PET systems.

We prospectively evaluated the performance of a dPET system in patients with cancer, as compared to high-resolution (HR) cPET imaging. Methods After a single FDG-injection, 66 patients underwent dPET (Vereos, Philips Healthcare) and cPET (Ingenuity TF, Philips Healthcare) imaging in a randomized order. We used HR-reconstructions (2x2x2 mm3 voxels) for both scanners and determined SUVmax, SUVmean, lesion-to-background ratio (LBR), metabolic tumor volume (MTV) and lesion diameter in up to 5 FDG-positive lesions per patient. Furthermore, we counted the number of visible and measurable lesions on each PET scan. Two nuclear medicine specialists blindly determined the Tumor Node Metastasis (TNM) score from both image sets in 30 patients referred for initial staging. For all 66 patients, these specialists sepPET.

Recent development of quinoline-based ligands targeting cancer-associated fibroblasts demonstrated promising preclinical and clinical results. The current study aimed to evaluate the role of fibroblast activation protein inhibitors (FAPI)-positron-emission tomography (PET)/computed tomography (CT) for primary malignancies located within the lower gastrointestinal tract (LGT) as a very first clinical analysis. Methods 68Ga-FAPI-PET/CT was performed in a cohort of 22 patients with LGT including 15 patients with metastatic disease, 1 patient with suspected local relapse and 6 treatment-naïve patients. 68Ga-FAPI-04 and 68Ga-FAPI-46 uptake was quantified by standardized uptake values (SUV)max and (SUV)mean. After comparison with standard imaging, changes in tumor stage/ localization and (radio)oncological management were recorded. Results The highest uptake of FAPI tracer was observed in liver metastases and anal cancer with a SUVmax of 9.
