Summary: The relationship between tumor and pleura is a risk factor for occult lymph node metastasis (OLNM) in peripheral clinical stage IA solid adenocarcinoma. Patients with type 3 or 4 tumor-pleura relationship are more likely to have visceral pleural invasion and predict OLNM.

Summary: A study was conducted on 1,000 LDCT scans for pulmonary nodule screening, comparing the performance of thick and thin scans. The study found that trained neural networks outperformed human doctors in detecting small nodules (<6.0mm), while human doctors had a slight advantage for larger nodules (>6.0mm). The combination of artificial intelligence and human doctors showed promise for achieving fast and accurate diagnosis.

Summary: The study aimed to analyze the diagnostic performance and prognostic value of CT-defined visceral pleural invasion (CT-VPI) in early-stage lung adenocarcinomas. The findings suggest that the diagnostic performance and prognostic value of CT-VPI are limited in clinical stage I lung adenocarcinomas and may be applicable only to radiologically solid tumors with higher intraobserver consistency.

Summary: This study compared the impact of the ultra-high resolution (UHR) images of a photon-counting CT (PCCT) scanner with the high-resolution (HR) images of an energy-integrating detector CT (EID-CT) on lung parenchyma analysis. It found that using the UHR scanning mode improved the visibility and identification of ILD features, leading to the reclassification of ILD patterns, all while reducing radiation dose.

Summary: In evaluating 117 patients with pathologically proven liver fibrosis, it was found that iodine uptake parameters from hepatic multiphasic CT can more accurately predict liver fibrosis, and the dual-energy iodine density method has higher inter-observer reproducibility and predictive values compared to the single-energy contrast enhancement method.

Summary: The photon-counting detector (PCD) is a new technology that provides significant benefits for cardiac and coronary artery imaging. Compared with conventional CT, PCCT has improved capabilities such as multi-energy capability, increased spatial resolution, reduced radiation exposure, and optimized use of contrast agents. It also overcomes limitations of traditional CCT/CCTA, such as reducing artifacts and enabling more precise assessment of stenosis and plaque characteristics. PCCT also has potential applications in characterizing myocardial tissue using a double-contrast agent.

Summary: Coronary artery disease is a leading cause of death globally, and computed tomography coronary angiography is a noninvasive imaging procedure used for its diagnosis. Researchers have developed a CT-compatible 2.5-MHz cardiac phased array transducer to improve the reliability of cardiac gating during CTCA.

Summary: The increasing use of CT and CBCT in oral and maxillofacial imaging has led to the development of deep learning and radiomics applications for maxillofacial disease diagnosis and management. Deep learning models have been developed for automatic diagnosis, segmentation, and classification of various maxillofacial diseases, while radiomics applications mainly focus on diagnosing occult metastasis and osteoarthritis. These models show high performance and have the potential for clinical use, but challenges in generalizability and reproducibility need to be addressed.

Summary: This study investigated the association between pre-/perinatal reduced optimality and child development observed by parents at 1 month, as well as NDDs at 3 years of age. The results showed that total reduced optimality scores were positively associated with both 1-month developmental concerns and 3-year NDDs. Various pre-/perinatal factors were found to be associated with developmental issues and NDDs in children.

Summary: Occupational lung disease presents complex radiologic findings, making it a challenge for computer-assisted diagnosis (CAD). Texture analysis was developed in the 1970s for diffuse lung disease. Pneumoconiosis appears on X-rays as a combination of small opacities, large opacities, and pleural shadows. The International Classification of Radiograph of Pneumoconioses is an ideal system for CAD using artificial intelligence (AI), which includes machine learning and convolutional neural networks. Common algorithms such as Alex-net, VGG16, and U-Net are used for the diagnosis of diffuse lung disease, including occupational lung disease. We describe the long journey in the development of CAD for pneumoconioses and propose a new expert system.

Summary: This study aimed to investigate the association between pre- and post-pregnancy maternal smoking status and bronchial asthma at 3 years of age. The results showed that children of mothers who sustained smoking during pregnancy had an increased risk of bronchial asthma at 3 years of age. Additionally, children of mothers who quit smoking before or after recognizing the current pregnancy also had an increased risk of bronchial asthma.

This study proposes a filter blot method for monitoring 3-NT in atmospheric PM, which is an indicator of air pollution. The method showed a significant correlation with the traditional HPLC-ECD method and can be a practical tool for environmental monitoring.
