464 Background: FDG PET/CT scan (PET) has been approved by Cancer Care Ontario since 2011 for pancreatic cancer patients who have potentially resectable disease. A recent prospective study supported the use of PET in patients with a pancreatic mass and showed improved staging accuracy. Herein, ...
Ontario, Canada, and colleagues studied 88 healthy individuals (average age 33) between 1999 and 2003. Participants underwent one positron emission tomography (PET) scan to assess serotonin transporter binding potential value, an index of serotonin...
were recruited from the community and were evaluated using the same clinical assessment and PET imaging protocol as those in the autopsy cohort to determine (among individuals who presumably had no β-amyloid) the proportion that were categorized correctly by a florbetapir-PET scan as amyloid negativ...
Conclusion: Improvements in OS were seen in this cohort of stage III NSCLC patients who underwent a pre-treatment FDG-PET/CT scan. This can likely be attributed to stage-appropriate therapy due to more complete staging using FDG-PET/CT. This study stresses the importan...

PET scan results were described by method of measuring FDG-PET avidity, the levels of risk or avidity, and the standardized uptake value threshold used to differentiate benign and cancerous diagnosis of disease. Details of study selection, data extraction, and synthesis are described in the e...
Thirteen patients from group 2, who underwent a second PSMA PET scan as a followup, were evaluated to determine the significance of PSA changes as a follow-up marker. Results: In group 1, 4 patients (12.9%) showed a PSA decline, of whom 2 patients and 1 patient showed a PSA decline ...
However, a limitation of PET/CT for post-treatment evaluation is seen in the setting of a positive PET scan. Gupta et al. [11 ••] found low positive predictive values for the primary tumor (59 %) and nodal disease (52 %), which indicate the tracer, FDG, is not tumor-specific....
This simulates variations in the adjustment of the segmentation of the LV on the PET-scan. For the simplest CNN, referred to as “CNN 1”, we input the matrices and used a convolution layer with 64 filters of size \(5 \times 5\), before the Global Average Pooling (GAP) layer. The...
