Summary: Elevating the diameter threshold for solid nodules from 6 to 9 mm may lead to a substantial reduction in unnecessary follow-up LDCTs with a small proportion of diagnostic delay of lung cancers.

Summary: The use of chest radiography as the first-line investigation in primary care patients with suspected lung cancer may have negative consequences, as a normal chest X-ray result may be misleading and resources may be prioritized for advanced disease.

Summary: This study develops an accurate and clinically relevant CT pulmonary angiography (CTPA) lung segmentation model, which has been evaluated on two diverse patient cohorts with pulmonary hypertension (PH) and interstitial lung disease (ILD). The model shows high accuracy and minimal clinical errors, making it suitable for clinical use in lung volume or parenchymal disease quantification.

Summary: This study demonstrated that simple attenuation measurements using VNC imaging can predict the presence of anemia and differentiate between healthy individuals and those with varying degrees of anemia. A linear relationship between HbS and attenuation on VNC suggests a potential for accurate prediction of anemia based on contrast-enhanced SDCT examinations.

Summary: This study assessed interobserver agreement in Lung-RADS categorisation of subsolid nodules in low-dose screening CTs, showing higher concordance among experienced thoracic radiologists. Overall, the interobserver agreement was moderate.

Summary: This study evaluated the variability in computer-assisted interpretation of LDCTs among radiologists in a nationwide lung cancer screening program. The results showed significant differences in positive rates and variability between institutional readings and central reviews, indicating that the different usage of computer-assisted systems is a major factor in inter-institution variability.

Summary: This study compared the ability of morphological and texture features derived from contrast-enhanced CT in histological subtyping of epithelial ovarian carcinoma (EOC). The study found that HGSC demonstrated higher texture features than non-HGSC, and both models performed well in predicting histological subtypes of EOC. Texture analysis provided objective and quantitative metrics on tumor characteristics and exhibited high classification accuracy for EOC subtypes.

Summary: Low-dose computed tomography (LDCT) with deep learning reconstruction (DLR) can improve image quality and assess lung parenchyma effectively. LDCT has significantly lower radiation dose compared to regular-dose CT (RDCT). LDCT DLR has better image quality and performs well in evaluating pulmonary lesions, except for subsolid nodules and decreased lung attenuation, compared to RDCT.

Summary: This study found that chest CT can predict the occurrence of CLAD in lung transplant patients. Moderate pulmonary artery stenosis, mosaic pattern of lung parenchyma, consolidations, and pleural effusions were identified as risk factors for CLAD.

Summary: The study assessed the interobserver agreement and clinical significance of chest CT reporting in patients suspected of COVID-19, showing good agreement between observers. Among patients suspected of COVID-19, CT categorized as evocative is highly predictive of COVID-19, while the predictive value decreases between the categories compatible and not evocative.

Summary: This study compared the performances of lung ultrasonography (LUS) and chest CT in assessing peripheric pulmonary lesions in patients with hemorrhagic fever with renal syndrome (HFRS). The results showed that LUS had high sensitivity and negative predictive value for diagnosing the pathologies, but relatively low specificity and positive predictive value. LUS can be used as an excellent rule-out tool in HFRS.

Summary: This study aimed to determine the rate of SPLC in individuals with a history of cancer undergoing LDCT lung cancer screening, finding a higher occurrence rate than previously reported. The results suggest the need for further research to evaluate the potential mortality benefit of screening in this population.

Summary: Micro- and nanoscopic X-ray techniques were used to investigate the relationship between uranium tissue distributions and adverse effects on the digestive tract of Daphnia magna. The study showed that exposure to uranium nanoparticles (UNPs) resulted in adverse morphological changes to the midgut and hepatic ceca, as well as abnormal intestinal epithelial cells. High-resolution nano-XRF identified U particulates throughout the midgut and within hepatic ceca cells, coinciding with tissue damages. These findings highlight the importance of disrupted intestinal function as a mode of acute U toxicity in D. magna.

Summary: Routine CT-screening increases the rate of incidental findings, primarily by identifying more pulmonary findings requiring follow-up. Incidental findings are more prevalent in patients with a history of smoking, and preoperative CT may increase the yield of identifying lung cancer in these patients. Incidental findings, but not specifically the use of routine CT, are associated with delay of surgery.

Summary: The yield of ULDCT is higher than CXR in patients with suspected infection but without respiratory symptoms or signs. ULDCT has a higher sensitivity in detecting pneumonia compared to CXR.
