Case studies: urgent decisions in interventional radiology
Published in William H. Bush, Karl N. Krecke, Bernard F. King, Michael A. Bettmann, Radiology Life Support (Rad-LS), 2017
Discussion A pneumothorax following a lung biopsy is a well-known occurrence. The incidence is as high as 20–30 per cent, and is a function of the location of the lesion (pleural based vs. central), needle size and number of needle passes. In general, such pneumothoraces are either asymptomatic or present with pleuritic chest pain, occasionally accompanied by dyspnea and/or hypoxia. They can often be assessed with fluoroscopy, but an upright chest film may be required. A chest tube is sometimes indicated and, if so, a small-bore (8-Fr.) pigtail-shaped catheter can be placed and left to suction or even to a unidirectional Heimlich valve. In our experience, a small catheter placed laterally in the mid-axillary or anterior-axillary line is more effective than one in the mid-clavicular line. It is equivalent to a large chest tube.
Bronchiolitis obliterans organizing pneumonia induced by drugs or radiotherapy

One case report showed a 71-year-old woman who completed right-sided breast radiation and developed a fever, sweats and unproductive cough 9 months later.69 A chest CT scan showed a dense infiltrate with air bronchograms in the right mid-lung. Bronchoscopy lung biopsy showed BOOP. There was a dramatic resolution of symptoms within a week, and 3 weeks later the chest CT scan showed complete resolution.
Hazardous dusts from the fabrication of countertop: a review

Autoimmune disorders have also been described in patients with ESD-associated silicosis. Shtraichman et al. found that in 40 cases of silicosis in Israeli countertop fabricators, 9 (23%) presented autoimmune symptoms.53 Of these nine subjects, six reported symptoms of arthritis, four Raynaud’s disease, two dysphagia, one myalgia, and one xerostomia. Six out of nine subjects were smokers, a factor which has been found to exacerbate silicosis and autoimmunity.54 Turner et al. recently identified a group of three Australian workers with an average exposure duration of 19.3 years. In addition to functional deficits, these workers presented clinical features of autoimmunity including arthropathy, sicca, Raynaud’s phenomenon, and positive autoantibody titers. A common theme among these workers was dry cutting techniques generating very high exposures, coupled with minimal or no respiratory PPE.55 In a survey of 18 cases of ES workers with silicosis across several states, Rose et al. identified five workers with symptoms of autoimmune disease. This subset of patients was found to suffer from either rheumatoid arthritis or scleroderma. Crucially, in some workers who presented with autoimmune symptoms, silicosis was not initially suspected. Only after lung biopsy was performed on these subjects was their silicosis discovered.4
Hybrid Deep Learning Model and Fuzzy C Means Clustering Method for Pulmonary Nodule Detection in CT Images
Published in IETE Journal of Research, 2022
This dataset consists of CT and PET-CT DICOM images of lung cancer subjects with XML Annotation files that indicate tumor location with bounding boxes. The images were retrospectively acquired from patients with a suspicion of lung cancer and who underwent standard-of-care lung biopsy and PET/CT. Subjects were grouped according to a tissue histopathological diagnosis. Patients, with Names/IDs containing the letter “A”, were diagnosed with Adenocarcinoma, “B” with Small Cell Carcinoma, “E” with Large Cell Carcinoma, and “G” with Squamous Cell Carcinoma. The images were analyzed on the mediastinum (window width, 350 HU; level, 40 HU) and lung (window width, 1,400 HU; level, –700 HU) settings. The reconstructions were made in 2 mm-slice-thick and lung settings. The CT slice interval varies from 0.625 to 5 mm. Scanning mode includes plain, contrast, and 3D reconstruction [26]. The comparison analysis of the proposed method is presented in Table 2.
Secure medical digital twin via human-centric interaction and cyber vulnerability resilience
Published in Connection Science, 2022
We aim to develop a new medical digital twin (MDT) with a focus on lung biopsy. Traditional lung biopsy navigation systems have two stages, preoperation and interoperation. The interoperation has two concerns: the operational tool's real-time location and the next stage of the operation. During the whole process, each of the guiding clues should be available for the surgeon in real time. For professional surgeons, the real-time force feedback from the hands may be more sensitive and important than the image guiding clues. In the new MDT, the haptic sensation is introduced in the interoperation stage to assist the image guiding for lung biopsy. We propose a new haptic-AR-enabled guiding method with deep learning to improve the robustness of the lung MDT.
