Figure Lengend Snippet: Proposed detector-splitting phantom scanning and harmonisation strategy for LAFOV PET. a Differences in scanning protocols and clinical workflows between LAFOV PET and SAFOV PET; b Scout image-based detector-splitting strategy. The long-axial detector is segmented into five positions (head, chest, abdomen, pelvis, and leg); c Phantom scanning performed sequentially at the different detector positions

Article Snippet: At baseline, a SAFOV PET/CT scan (Gemini 64, Philips, 18 F-FDG) in March 2025 demonstrated diffuse thickening of the gastric wall involving the gastric angle and antrum, with an SUV max of 21.30.

Figure Lengend Snippet: Application of detector-splitting phantom scanning and SUV harmonisation strategy to clinical PET images. a SAFOV PET image of a DLBCL patient acquired in March 2025. The gastric lesion measures 7.35 × 3.05 cm, with an SUV max of 21.30. b LAFOV PET image (before SUV harmonisation) of the same patient after four cycles of chemotherapy, acquired in July 2025. The gastric lesion measures 3.72 × 2.19 cm, with an SUV max of 32.94. c LAFOV PET image (after SUV harmonisation) of the same patient, acquired in July 2025. The SUV max of the gastric lesion is 22.98

Article Title: Feasibility of shortening the 18 F-FDG Patlak scan time in a high-sensitivity short-axial field-of-view positron emission tomography-computed tomography system for oncological studies using deep learning denoising algorithms

doi: 10.21037/qims-2025-1757

Figure Lengend Snippet: Four dynamic whole-body Patlak imaging protocols were derived from a dual-injection FDG-PET scanning method. The initial injection occurred at time zero, with the second injection being administered approximately 80 min later. The 41 to 75 min interval was used for Patlak analysis, while the remaining periods (0–6, 7–40, and 80–86 min) were designated for generating various types of AIF. AIF, arterial input function; FDG, fluorodeoxyglucose; PET, positron emission tomography.

Article Snippet: The external datasets consisted of 510 participants with a 50% and 100% full-dose WB FDG-PET scan collected from the Ultra-low Dose PET Challenge ( https://ultra-low-dose-pet.grand-challenge.org ), which includes different levels of low-count FDG-PET and full-dose FDG-PET scans acquired from the Biograph Vision Quadra (Siemens Healthineers) and the uEXPLORER (United Imaging Healthcare, Shanghai, China) scanners.

Techniques: Imaging, Derivative Assay, Injection, Positron Emission Tomography
