“…d Voxel form of the resulting augmented airway tree segmentation branches in B necessary to reach a particular ROI from the trachea. Note that the term "bronchial generation" refers to the number of bronchial branches constituting a route; this follows other recent works in image-guided bronchoscopy [9,[12][13][14][15]. As stated earlier, the airway bifurcation points are the essential landmarks needed by the bronchoscopist during navigation, and these are the points that terminate each bronchial generation.…”

“…The proposed airway route-definition system constitutes part of a large IGI suite we have been developing for the planning and guidance of bronchoscopy [9,[17][18][19][20]. Use of the complete IGI suite involves the following major stages: (a) procedure planning; (b) procedure preview; and (c) live image-guided bronchoscopy.…”

“…The system described in this paper focuses on procedure planning. Companion works discuss procedure preview, which involves a virtual rehearsal of the procedure plan [18,20], and imageguided bronchoscopy, which entails performing the desired bronchoscopy under guidance from the plan [9,17,19]. "Results" also illustrates the use of a plan for image-guided bronchoscopy.…”

“…Hence, considerable recent research has focused on using bronchoscopy for peripheral nodule biopsy [3,4,7]. Unfortunately, it has long been known that physicians vary considerably in their ability to navigate a bronchoscope correctly to peripheral diagnostic sites [8,9].…”

“…This poor performance in mental procedure planning directly impacts performance during later bronchoscopy. A recent study demonstrated that 14 bronchoscopists could navigate successfully to only 31% of ROIs situated six to eight bronchial generations into the lungs [9]. Thus, it is well recognized that some form of image-based route planning prior to a procedure is imperative [12,13].…”

Multi-detector computed tomography (MDCT) scanners produce high-resolution images of the chest. Given a patient's MDCT scan, a physician can use an image-guided intervention system to first plan and later perform bronchoscopy to diagnostic sites situated deep in the lung periphery. An accurate definition of complete routes through the airway tree leading to the diagnostic sites, however, is vital for avoiding navigation errors during image-guided bronchoscopy. We present a system for the robust definition of complete airway routes suitable for image-guided bronchoscopy. The system incorporates both automatic and semiautomatic MDCT analysis methods for this purpose. Using an intuitive graphical user interface, the user invokes automatic analysis on a patient's MDCT scan to produce a series of preliminary routes. Next, the user visually inspects each route and quickly corrects the observed route defects using the built-in semiautomatic methods. Application of the system to a human study for the planning and guidance of peripheral bronchoscopy demonstrates the efficacy of the system.

This review compares the emerging technologies and approaches in the application of magnetic resonance (MR) and computed tomography (CT) imaging for the assessment of pulmonary nodules and staging of malignant findings. Included in this review is a brief definition of pulmonary nodules and an introduction to the challenges faced. We have highlighted the current status of both MR and CT for the early detection of lung nodules. Developments are detailed in this review for the management of pulmonary nodules using advanced imaging, including: dynamic imaging studies, dual energy CT, computer aided detection and diagnosis, and imaging assisted nodule biopsy approaches which have improved lung nodule detection and diagnosis rates. Recent advancements linking in vivo imaging to corresponding histological pathology are also highlighted. In vivo imaging plays a pivotal role in the clinical staging of pulmonary nodules through TNM assessment. While CT and positron emission tomography (PET)/CT are currently the most commonly clinically employed modalities for pulmonary nodule staging, studies are presented that highlight the augmentative potential of MR. LUNG CANCER remains a challenging disease to effectively identify, diagnose, and treat, as reflected by the 5-year survival rate, which remains similar to that of 15 years ago at 13%. Lung cancer frequently manifests as a peripheral lung nodule or mass. Radiologically identified lesions in the lung that are less than 30 mm in diameter are defined as pulmonary nodules, while those greater than 30 mm are termed masses (1). Both pulmonary nodules and masses present specific challenges in the evaluation of suspected lung cancer; however, the greatest impact of x-ray computed tomography (CT) and magnetic resonance imaging (MRI) developments have been on the detection and characterization of pulmonary nodules. Hence, the scope of this review will focus on the recent advances in CT and MRI of pulmonary nodules and lung cancer staging, highlighting the respective strengths and weaknesses of these modalities. X-ray chest radiography (CXR) is the most widely utilized modality for pulmonary abnormalities and disease screening, although sonography has been utilized in limited situations in the chest. In addition, positron emission tomography (PET) or PET/CT with 2-deoxy-2-[18F]fluoro-D-glucose (FDG) is currently widely utilized for differentiation of malignant lesions from benign lesions, staging of malignant tumors, and assessment of therapeutic effects after conservative therapy. The value of CT and MR for depicting structural anatomy is widely appreciated and applied clinically to noninvasively identify abnormalities and/ or disease. Recent developments of imaging techniques and processing have expanded the potential of these modalities to include combined structure and function. Recent exciting work for the detection, monitoring, characterization, and staging of pulmonary cancer nodules using imaging of both CT and MR modalities will be summarized in this review.While the overall...
