Vibration Response Imaging (VRI) in Patients Who Are Potential Candidates for Surgical Resection
The primary purpose of the study is to investigate the use of VRI to guide the selection of patients for lung surgery. Perfusion scintigraphy is the current method to assess the fractional contribution of lung function of the remaining lung.
The hypothesis is that VRI can determine quantitative postoperative lung function equally accurately as a quantitative perfusion scan.

Beschrijving
Inclusion Criteria:
- Able and willing to read, understand, and provide written Informed Consent;
- Age range of 18-90 years;
- Potential candidate for at least lobectomy due to lung cancer or other intrathoracic malignancy (either suspected or proven by biopsy). Both open and minimally invasive (thoracoscopic) resections are acceptable.
- BMI > 19.
Exclusion Criteria:
- Body habitus or skin condition that might prevent the placement of the sound sensors on the back (e.g. severe scoliosis, kyphosis, chest wall deformation, skin lesion on the back or compression fracture);
- There should be no active pulmonary infection (e.g. pneumonia) at the time of the recordings;
- Hirsutism unless patient is willing to have back shaved;
- Potentially contagious skin lesion on the back;
- Giant bulla (more than 1/3 of the hemithorax or >10cm)
- Pregnant women

Lung resection candidates
Study participants will be patients who are candidates for lung resection (lobectomy or greater)
|
The study is designed in a way that will not alter the surgeon's decision based on routine assessment of candidates for resection (lobectomy or greater).
Namely, the VRI data will be gathered prospectively; however, the analyses using VRI data will be performed retrospectively.
