Background Intratumor heterogeneity in lung cancer may influence outcomes. CT radiomics seeks to assess tumor features provide detailed imaging features. However, radiomic vary according the reconstruction kernel used for image generation. Purpose To investigate effect of different kernels on and whether conversion using a convolutional neural network (CNN) could improve reproducibility between kernels. Materials Methods In this retrospective analysis, patients underwent non–contrast...
Background The diagnostic abilities of multimodal large language models (LLMs) using direct image inputs and the impact temperature parameter LLMs remain unexplored. Purpose To investigate ability GPT-4V Gemini Pro Vision in generating differential diagnoses at different temperatures compared with radiologists
Background: In lung adenocarcinomas manifesting as part-solid lesions, evidence supports greater prognostic importance for the volume of solid component than whole nodule. However, assessments lesion growth rates have historically focused on doubling time (VDT) lesion. Objective: To compare utility VDT versus resected lesions chest CT. Methods: This retrospective study included 122 patients (mean age, 64.0 ± 8.2years; 53 men, 69 women) with adenocarcinoma a who underwent at least two...
Background Evaluation of interstitial lung disease (ILD) at CT is a challenging task that requires experience and subject to substantial interreader variability. Purpose To investigate whether proposed content-based image retrieval (CBIR) similar chest images by using deep learning can aid in the diagnosis ILD readers with different levels experience. Materials Methods This retrospective study included patients confirmed after multidisciplinary discussion available identified between January...
The progressive fibrosing (PF) phenotype of interstitial lung disease (ILD) is characterised by worsening respiratory symptoms, function, and extent fibrosis on high-resolution computed tomography. We aimed to investigate the prevalence clinical outcomes PF-ILD in a real-world cohort assess prognostic significance diagnostic criteria.Clinical data patients with ILD other than idiopathic pulmonary (IPF) consecutively diagnosed at single centre were retrospectively reviewed. A PF was defined...
Rationale: The optimal follow-up computed tomography (CT) interval for detecting the progression of interstitial lung abnormality (ILA) is unknown. Objectives: To identify strategies and extent thresholds on CT relevant to outcomes. Methods: This retrospective study included self-referred screening participants aged 50 years or older, including nonsmokers, who had imaging findings ILA chest scans. Consecutive scans were evaluated determine dates initial showing progression. Deep...
Background: In certain patients with lung cancer, guidelines recommend endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) as the primary method to evaluate for metastatic mediastinal lymph nodes, defining pN2 disease. EBUS-TBNA has associated costs and complications possibly limited availability. Objectives: To investigate prevalence risk factors disease in undergoing resection of cancer assessed having radiologic N0 or N1 Methods: This retrospective study included...
Objective:The aim of our study was to develop and validate a convolutional neural network (CNN) architecture convert CT images reconstructed with one kernel different reconstruction kernels without using sinogram.Materials Methods: This retrospective approved by the Institutional Review Board.Ten chest scans were performed B10f, B30f, B50f, B70f kernels.The dataset divided into six, two, two examinations for training, validation, testing, respectively.We constructed CNN consisting six...
Patients with fibrotic hypersensitivity pneumonitis (HP) show variable clinical courses, and some experience rapid deterioration (RD), including acute exacerbation (AE). However, little is known about AE in HP. Here, we retrospectively examined the incidence, risk factors, outcomes of HP.The incidence rates were calculated 101 patients biopsy-proven was defined as worsening dyspnoea within 30 days, new bilateral lung infiltration no evidence infection or other causes dyspnoea.During...
Background Although lung adenocarcinoma with ground-glass opacity (GGO) is known to have distinct characteristics, limited data exist on whether the recurrence pattern and outcomes in patients resected differ according GGO presence at CT. Purpose To examine patterns associations Materials Methods Patients who underwent CT followed by lobectomy or pneumonectomy for between July 2010 December 2017 were retrospectively included. divided into two groups based of GGO: solid adenocarcinoma....
Pulmonary nocardiosis is a rare opportunistic infection with occasional systemic dissemination. This study aimed to investigate the computed tomography (CT) findings and prognosis of pulmonary associated
The aim of our study was to assess the performance content-based image retrieval (CBIR) for similar chest computed tomography (CT) in obstructive lung disease. This retrospective included patients with disease who underwent volumetric CT scans. CBIR database 600 scans from 541 patients. To system performance, follow-up 50 were evaluated as query cases, which showed stability findings between baseline and CT, confirmed by thoracic radiologists. retrieved top five each case quantifying...
In patients who underwent surgery for non–small lung cancer, CT-defined bulky lymph nodes (≥15 mm) served as an effective descriptor clinical N1 staging, improving prognostic stratification.
