Evaluation of the utility of vibration response imaging device and Operation Planning Software in the assessment of patients before lung resection surgery☆

Abstract

VRI(XP) O-Plan has shown high accuracy in predicting postoperative FEV(1) after lung resection surgery. Given its simplicity of operation and the non-invasive nature of VRI(XP) and O-Plan, it could be a good alternative to perfusion scan in pre-surgery assessment.

A New Method to Predict Postoperative Lung Function: Quantitative Breath Sound Measurements

“…sounds during spontaneous breathing [7,8] and demonstrated similar results for both methods. We undertook a prospective multicenter study at 6 United States sites to validate whether quantitative lung sound measurements are a simpler alternative to radionuclide tests for estimation of postoperative lung function in this patient population.…”

“…Recordings with artifacts were excluded. The "O-Plan" software automatically calculates each lung's total vibration energy Ϯ standard deviation as an average of 2 or more goodquality recordings of the respiratory cycle [8]. The standard deviation provides feedback on the reliability of the recorded data.…”

“…The percentage of that lung's function attributed to a lobe to be resected can be estimated from the number of segments in that lobe relative to the whole lung (modified segment-counting method) or by drawing horizontal lines to arbitrarily divide the lung into thirds (zones) and attributing the function of such an area with that of a lobe (zone method). Previous studies comparing PPO estimations by VRI and perfusion have used the zone method [7,8]. This study was based on the modified segment-counting method to avoid confounding arising from comparing the arbitrary division into zones for one test (perfusion) with that for another (VRI); however, an analysis using the zone method was also performed.…”

Application of vibration response imaging technology in patients with community-acquired pneumonia before and after the treatment

“…It has wide prospect in clinical application. Previous studies were focused on the characteristics of VRI images of healthy populations and evaluation of equipment performance and pneumonectomy and mechanical ventilation were mainly involved for diseases (5–8), were mainly on airflow limited diseases (8,9). However, there were few literature reports that applied this technology in infectious diseases of the lungs.…”

Vibration response imaging versus perfusion scan in lung cancer surgery evaluation

“…Vibration response imaging (VRI) is a new, noninvasive, simple to use technique that can provide an accurate estimate of ppoFEV1. 4 In a previous study by Jimenez and colleagues, 5 VRI-based measures have shown high accuracy in the prediction of ppoFEV1.…”
