Vibration Response Imaging (VRI) in Patients Who Are Potential Candidates for Surgical Resection

Primarily, VRI will be compared to perfusion (Q) scan by predicted post-operative (ppo) FEV1
and DLCO as predicted by VRI versus as predicted by Q scan. Secondary, the ppo as predicted
by each test will be compared with the actual FEV1 and DLCO at 3 months post-operative; If
these two methods provide similar results, VRI will be deemed an acceptable alternative to Q
scan for determining patient selection for lung resection. Finally, the patient outcomes (30
day mortality and pulmonary complications) for those patients falling within guideline
parameters using the VRI measurement will be analyzed to see if using VRI in clinical
practice would indeed allow prediction of satisfactory results (similar to literature

Inclusion Criteria:

1. Able and willing to read, understand, and provide written Informed Consent;

2. Age range of 18-90 years;

3. 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.

4. BMI > 19.

Exclusion Criteria:

1. 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);

2. There should be no active pulmonary infection (e.g. pneumonia) at the time of the

3. Hirsutism unless patient is willing to have back shaved;

4. Potentially contagious skin lesion on the back;

5. Giant bulla (more than 1/3 of the hemithorax or >10cm)

6. Pregnant women
