Modalities to detect and characterize lung cancer are generally divided into those that are invasive [endobronchial ultrasound (EBUS), esophageal ultrasound (EUS), and electromagnetic navigational bronchoscopy (ENMB)] versus noninvasive [chest radiography (CXR), computed tomography (CT), positron emission tomography (PET), and magnetic resonance imaging (MRI)]. This chapter describes these modalities, the literature supporting their use, and delineates what tests to use to best evaluate the patient with lung cancer...

We have recently developed a flexible catheter electrode used for bronchoscopic radiofrequency ablation (RFA). Two patients with nonsurgical stage IA peripheral lung cancer and 1 with lung metastasis underwent treatment with flexible catheter RFA utilizing navigation bronchoscopy. Chest computed tomography (CT) and positron emission tomography/CT (PET/CT) were performed before and after RFA to assess the ablation response of the patients. One patient's tumor had no prior PET uptake and therefore no follow-up PET was obtained...

BACKGROUND: Electromagnetic navigational bronchoscopy (ENB) is guided bronchoscopy to pulmonary nodules (PN) that relies on a preprocedural chest CT to create a three-dimensional (3D) virtual airway map. The CT is traditionally done at a full inspiratory breath hold (INSP), but the procedure is performed while the patient tidal breaths, when lung volumes are closer to functional residual capacity. Movement of a PN from INSP to expiration (EXP) has been shown to average 17.6 mm. Therefore, the hypothesis of this study is that preprocedural virtual maps built off a CT closer to physiological lung volumes during bronchoscopy may better represent the actual 3D location of a PN...

OBJECTIVE: In flexible endoscopy techniques, such as bronchoscopy, there is often a challenge visualizing the path from start to target based on preoperative data and accessing these during the procedure. An example of this is visualizing only the inside of central airways in bronchoscopy. Virtual bronchoscopy (VB) does not meet the pulmonologist's need to detect, define and sample the frequent targets outside the bronchial wall. Our aim was to develop and study a new visualization technique for navigated bronchoscopy...

PURPOSE: One of the major challenges in electromagnetic navigated bronchoscopy is the navigation accuracy. An initial rigid image-to-patient registration may not be optimal for the entire lung volume, as the lung tissue anatomy is likely to have shifted since the time of computer tomography (CT) acquisition. The accuracy of the initial rigid registration will also be affected throughout the procedure by breathing, coughing, patient movement and tissue displacements due to pressure from bronchoscopy tools...

BACKGROUND: Navigational bronchoscopy and other imaging modalities have improved the ability to evaluate pulmonary nodules/mass. Many of these lesions are located outside the bronchial airway and are difficult to access even with these devices. The Transbronchial Access Tool (Medtronic, Minneapolis, MN) allows the bronchoscopist to create a pathway from the bronchial airway, across the lung parenchyma, and into the target lesion. We are reporting the feasibility and safety of this new device...

PURPOSE: In bronchoschopy, computer vision systems for navigation assistance are an attractive low-cost solution to guide the endoscopist to target peripheral lesions for biopsy and histological analysis. We propose a decoupled deep learning architecture that projects input frames onto the domain of CT renderings, thus allowing offline training from patient-specific CT data. METHODS: A fully convolutional network architecture is implemented on GPU and tested on a phantom dataset involving 32 video sequences and [Formula: see text]60k frames with aligned ground truth and renderings, which is made available as the first public dataset for bronchoscopy navigation...

With the greater use of chest CT, the incidental detection of lung nodules is expected to increase. However, because most lung nodules are benign, there is a high demand for minimally invasive procedures that provide valuable diagnostic information while minimizing complications. Recent advances in bronchoscopic technology meet this demand. These advanced technologies include navigational bronchoscopy and radial endobronchial ultrasound (EBUS) for the diagnosis of peripheral lung nodules, and linear EBUS, which has revolutionized the nonoperative nodal staging of lung cancer and provides a complementary option to surgical staging approaches...

Lung cancer remains a common and deadly disease. Many modalities are available to the bronchoscopist to evaluate and stage lung cancer. We review the role of bronchoscopy in the staging of the mediastinum with convex endobronchial ultrasound (EBUS) and discuss emerging role of esophageal ultrasonography as a complementary modality. In addition, we discuss advances in scope technology and elastography. We review the bronchoscopic methods available for the diagnosis of peripheral lung nodules including radial EBUS and navigational bronchoscopy (NB) with a consideration of the basic methodologies and diagnostic accuracies...

BACKGROUND: Identification of small peripheral lung nodules during minimally invasive resection can be challenging. Electromagnetic navigational bronchoscopy (ENB) with injection of dye to identify nodules can be performed by the surgeon immediately prior to resection. We evaluated the effectiveness of ENB with dye marking to aid minimally invasive resection. METHODS: Patients with peripheral pulmonary nodules underwent ENB before planned thoracoscopic or robotic-assisted thoracoscopic resection...

Lung cancer continues to be the most common cause of cancer death. Screening programs for high risk patients with the use of low-dose computed tomography (CT) has led to the identification of small lung lesions that were difficult to identify using previous imaging modalities. Electromagnetic navigational bronchoscopy (ENB) is a novel technique that has shown to be of great utility during the evaluation of small, peripheral lesions, that would otherwise be challenging to evaluate with conventional bronchoscopy...

BACKGROUND: Electromagnetic navigational bronchoscopy (ENB) is a commonly used technique to obtain biopsies of peripheral pulmonary lesions. Little is known about risk factors for complications with this procedure. The aim of this study was to assess the complication rate associated with ENB and the relationship of complications to patient- and procedure-related factors. METHODS: Consecutive ENB procedures at an academic medical center between May 11, 2011, and September 11, 2015, were reviewed retrospectively...

PURPOSE: Electromagnetic tracking is the gold standard for instrument tracking and navigation in the clinical setting without line of sight. Whilst clinical platforms exist for interventional bronchoscopy and neurosurgical navigation, the limited flexibility and high costs of electromagnetic tracking (EMT) systems for research investigations mitigate against a better understanding of the technology's characterisation and limitations. The Anser project provides an open-source implementation for EMT with particular application to image-guided interventions...

Small (2 cm) peripheral lung lesions and ground glass opacities remain a difficult subset of lung lesions for the diagnosis and management of lung cancer. Surgical biopsy is more difficult for these lesions because intraoperative localization has to be made without the aid of direct visualization or manual palpation. Electromagnetic navigation bronchoscopy can be used in the operating room to identify a small peripheral lesion and marked using an injection of methylene blue, which can be seen on the visceral pleura of the lung...
