Abstract Purpose To assess the feasibility of Four-Dimensional Ultra-Low-Dose Computed Tomography (4D-ULDCT) for distinguishing pleural aspects with localized pleural adhesion (LPA) from those without. Methods Twenty-seven patients underwent 4D-ULDCT during a single respiration with a 16聽cm-coverage of the body axis. The presence and severity of LPA was confirmed by their intraoperative thoracoscopic findings. A point on the pleura and a corresponding point on the outer edge of the costal bone w...

This paper presents a new hybrid biomechanical model-based non-rigid image registration method for lung motion estimation. In the proposed method, a patient-specific biomechanical modelling process captures major physically realistic deformations with explicit physical modelling of sliding motion, whilst a subsequent non-rigid image registration process compensates for small residuals. The proposed algorithm was evaluated with 10 4D CT datasets of lung cancer patients. The target registration er...

Abstract Purpose Using 4-dimensional dynamic-ventilatory scanning by a 320-row computed tomography (CT) scanner, we performed a quantitative assessment of parietal pleural invasion and adhesion by peripheral (subpleural) lung cancers. Methods Sixteen patients with subpleural lung cancer underwent dynamic-ventilation CT during free breathing. Neither parietal pleural invasion nor adhesion was subsequently confirmed by surgery in 10 patients, whereas the other 6 patients were judged to have pariet...

Video-assisted thoracoscopic surgery (VATS) lobectomy has become a standard procedure for lung cancer treatment. Conversion-related factors and learning curve impacts, were poorly described. The aim of this study was to review the reasons and related factor for conversion in VATS lobectomy and the impact on this of the surgeon鈥檚 learning curve. From June 2009 to May 2014, 154 patients who underwent a VATS lobectomy were included in our study. Patients鈥 characteristics, pathology background, oper...

Rationale and Objectives To evaluate paired inspiratory/expiratory computed tomography (CT; iCT/eCT) and deformable image registration for quantitative and qualitative assessment of airflow limitation in smokers. Materials and Methods Paired iCT/eCT images acquired from 35 smokers (30 men and 5 women) were coregistered and subtraction images (air trapping CT images [aCT]) generated. To evaluate emphysema quantitatively, the percentage of low-attenuation volume (LAV%) on iCT was calculated at 鈭95...

OBJECTIVES: The 320-slice computed tomography (CT) provides three-dimensional and dynamic imaging resulting in the ability to assess motion analysis between two adjacent structures (the fourth dimension). Differential movements between two adjacent structures would indicate that there is no fixation between the two structures. METHODS: Eight patients with non-small-cell lung cancers located adjacent to vital structures (e.g. the great vessels) (n= 4), mediastinum (n= 1) or chest wall (n= 3) wher...

Objectives One objective was to evaluate the air trapping index (ATI), measured by inspiration/expiration CT, in COPD patients and nonsmokers. Another objective was to assess the association between the pulmonary function test (PFT) and CT parameters such as ATI or other indices, separately in the whole lung, in emphysema, and in hyperinflated and normal lung areas.

Background Chest wall invasion in operable lung cancer upgrades the stage and can affect operative planning. Diagnosing chest wall invasion preoperatively is important in patient consent, in the choice of operative incision placement, and can be helpful in choosing an operative approach (open vs thoracoscopic). The objectives of this study were to determine the diagnostic accuracy of preoperative, surgeon-performed ultrasound (US) in assessing tumoral chest wall invasion (T3) in non-small cell l...

Objective An accurate radiological method for evaluating the presence or extent of aortic invasion by thoracic cancer is essential in the preoperative setting. The aim of this study was to assess whether respiratory dynamic (RD) magnetic resonance imaging (MRI) more accurately detects aortic invasion of mediastinal tumors and lung cancer compared with conventional MRI or computed tomography (CT). Methods Twenty-six patients (19 male, 7 female; mean age, 63.08 卤 12.05 years) with inconclusive evi...
