The Role of a Vibration Response Imaging Device in the Selection of Patients for Lung Resection Surgery

BACKGROUND: Simpler and radiation free alternatives have been researched to estimate postoperative lung functions. Objective of the study is to investigate the reliability of predicted postoperative (ppo) forced expiratory volume in 1 second (FEV₁) and carbon monoxide diffusion capacity (DLCO) calculated by vibration response imaging (VRI) to guide the selection of patients for lung resection surgery in comparison with quantitative perfusion scintigraphy (Q scan). METHODS: 35 candidates for lung resection were enrolled in the study for preoperative and postoperative evaluation of FEV₁ and DLCO. RESULTS: Totally 25 patients had preoperative tests. VRI measurements showed strong correlation with Q scan measurements of predicted postoperative (ppo) FEV₁% (r= .87, p
