Solitary Pulmonary NodulesThe purpose of this study is to evaluate the imaging performance of Dual Energy and Digital Tomosynthesis (DE-DT) application against the commercially available predicate devices.
The Benefit of UHR-CT: Precision of Repeated Volume Measurements of Pulmonary Nodules
Pulmonary NoduleSolitaryTo assess the variability of semi-automated volume measurements of pulmonary nodules on same-day repeated scans of equal radiation dose from two different CT scanners: One high-end CT scanner with standard spatial resolution (CT1) and one UHRCT scanner (CT2), in patients with known or suspected pulmonary metastases.
Bronchoscopic Approach to the Peripheral Lung Nodule - An Alternative Approach
Solitary Pulmonary NoduleLung CancerPatients presenting with solitary or multiple lung nodules often require tissue confirmation in order to guide further management and determine if the lesion is benign or malignant. Several bronchoscopic techniques have emerged which have significantly improved the diagnostic yield of bronchoscopy in this setting, and in particular the combination of peripheral Endobronchial Ultrasonography (pEBUS) and Electromagnetic Navigation Bronchoscopy (ENB) has resulted in diagnostic yields of nearly 90%. In an attempt to reduce the significant cost of this combined approach, the sequential use of pEBUS followed by the more costly ENB technique only if a lesion is not identified on the ultrasound image could be as accurate. This study aims to determine the diagnostic yield of this sequential approach in patients with lung nodule(s).
Clinical Evaluation of Primary Sampling Scatter Correction for Chest Tomosynthesis

Chest Tube After a Video-assisted Thoracoscopic Surgery Pulmonary Wedge Resection
Lung DiseasesInterstitial2 moreAfter performing VATS pulmonary wedge resections, a chest tube is routinely left in the pleural cavity to drain possible air leaks and fluid accumulations. Chest tubes after VATS pulmonary wedge resections are left in place a minimum of 1 day. However, this practice has no scientific foundations. The investigators believe it is possible to avoid the placement of a chest tube after this procedure in a great amount of patients. This is a randomized controlled clinical trial with analysis blinding in which the investigators want to compare the outcomes between installing a chest tube or not after VATS pulmonary wedge resections. The investigators will include consecutively patients with interstitial lung disease or indeterminate pulmonary nodules undergoing this procedure, at the participating institutions. The investigators calculated a sample size of 50 subjects in each group using pneumothorax < 10% data from Luckraz et al and to determine a difference of hospital stay of 2 versus 1 day; DS(1.5), power = 0.9 and alpha = 0.05.

A Multi-Center Trial of the ProLung Test™
Solitary Pulmonary NoduleMultiple Pulmonary NodulesThe primary Study hypothesis is that the ProLung Test will demonstrate safety and efficacy in the risk stratification of patients with pulmonary lesions identified by CT that are suspicious for lung cancer. A statistically significant result will indicate that patients with a high ProLung Test result have a greater risk of developing lung cancer than patients with a low test result. There are three Specific Aims of this study: Optimize and confirm the stability of the ProLung Test risk-stratification algorithm in patients with a diagnosis. Externally validate the efficacy of the ProLung Test risk-stratification algorithm by comparing the test result to the conclusive patient diagnosis. Assess the safety and tolerability of the ProLung Test procedures. Study Design This Study consists of two distinct phases, Stabilization and Validation. The Study will collect data from multiple sites (3 to 12), and each site may enroll patients and collect data for the Stabilization and Validation Phases with a minimum of three sites for the Validation Phase.
Semi-barbed Suture for Pulmonary Small Nodules Localization
SutureNodule2 moreHookwire and microcoil are currently the most widely used localization instruments. Although their success rate is relatively high in preoperative localization attempts, they may lead to consequences that negatively affect patient outcomes, such as pain because of the metal's hardness, localization failure due to wire detachment, and the presence of permanent traces of metal and foreign bodies . To overcome these disadvantages, we designed an absorbable semi-barbed suture to localize small intrapulmonary nodules (patent number: ZL201821444387.X). The results of the previous animal experiments were satisfactory, and it is now necessary to recruit 10 patients for clinical trials.
