Perioperative Specimen Imaging Using High-resolution 18F-FDG-PET-CT During Thoracic Surgery: a Pilot Study

In this pilot study the investigators propose the intraoperative use of a high-resolution PET-CT imaging system which can assess resection margins and lymph node status in the operating room. This will allow for a faster and stepwise assessment (estimated to be under 10 minutes per specimen), enabling the surgeon to decide on subsequent surgical steps after each previous assessment.

Treatment and study plan

AURA10 Specimen Imager

Device

High-resolution specimen imaging using the AURA10 PET-CT specimen imager during thoracic surgery.

Primary outcomes

  1. Perioperative success in imaging utilizing AURA10 PET-CT Specimen Imager

    Time frame: Perioperative

    A measure of perioperative success in imaging 18F-FDG- uptake in resected specimens obtained during thoracic surgery utilizing a high-resolution PET-CT-scanner.

Secondary outcomes

  1. Sensitivity and specificity of high-resolution 18F-FDG-PET-CT of resected mediastinal or thoracic lymph nodes in terms of nodal staging.

    Time frame: Perioperative

  2. Sensitivity and specificity of high-resolution 18F-FDG-PET-CT of resected lung tumors in terms of bronchial margin assessment.

    Time frame: Perioperative

  3. Sensitivity and specificity of high-resolution 18F-FDG-PET-CT of resected lung tumors in terms of lung parenchyma margin assessment

    Time frame: Perioperative

  4. Correlation between 18F-FDG uptake in the resected specimens and histopathological characteristics of the tumor, such as the type, grade, or stage of the tumor.

    Time frame: Perioperative

  5. Measure signal-to-noise ratio on post-processed PET-CT specimen images.

    Time frame: Perioperative

  6. Comparison of lesion dimensions (e.g. delineation based on percentage of SUVmax, tumor-to-background ratios based on SUVpeak).

    Time frame: Perioperative

  7. Occupational radiation exposure (µSv) to the staff in the operating room related to this study.

    Time frame: Perioperative

  8. Correlation of high-resolution 18F-FDG-PET-CT images of lamellas of the resected specimen with histopathological whole-slide images.

    Time frame: Perioperative
