Summary: This study compared objective and subjective image quality and radiation dose between low-dose chest CT examinations in adult CF patients using a third-generation DSCT scanner and a 64-slices single-source CT (SSCT) scanner. The DSCT protocol showed lower radiation dose during inspiratory phase and higher radiation dose overall compared to the SSCT protocol, with improvements in subjective image quality.

Summary: This study aimed to illustrate the temporal change of lung abnormalities associated with COVID-19 pneumonia on chest CT scans over 1 year. The study found that residual lung abnormalities in individuals hospitalized with moderate COVID-19 pneumonia were infrequent, with no evidence of fibrosis at 1-year chest CT.

Summary: Low-dose chest CT is technically feasible, reduces dose, and renders satisfactory image quality for imaging in CF. Limited studies comparing low-dose chest CT with standard CT in CF show equivalent diagnostic capability. Low-dose chest CT with iterative reconstructive algorithms has potential for early detection of bronchiectasis and infective exacerbations, especially in asymptomatic patients.

Summary: The prognostic value of DL-driven CT fibrosis quantification in IPF was investigated. CT-Norm% and CT-Fib% showed significant correlations with FVC and D-LCO. Both CT-Norm% and CT-Fib% were independent prognostic factors for overall survival in IPF when adjusted for various variables. Substituting CT-Norm% for D-LCO showed comparable discrimination to the original GAP index.

Summary: This prospective study longitudinally assessed changes in chest CT abnormalities and pulmonary function in individuals after recovery from SARS-CoV-2 infection. The study found that more than one-third of the participants had persistent interstitial lung abnormalities 2 years after infection, which were associated with respiratory symptoms and decreased diffusion pulmonary function.

Summary: Cystic fibrosis is a disease characterized by chronic airway infection and progressive decline in respiratory function. Recent changes in the landscape of airway infection in CF have resulted in an increased prevalence of atypical gram-negative bacterial infections. The clinical relevance and treatment strategies for many of these lower prevalence organisms are still not well understood.

Summary: The study compares the performance of six state-of-the-art Deep Transfer Learning techniques in accurately classifying and localizing abnormalities in chest CT images of patients with Pulmonary Fibrosis (PF). The optimized ResNet50v2 model achieved the highest training and validation accuracy (training = 99.92%, validation = 99.22%) and minimum loss (training = 0.00428, validation = 0.00683) for CT images. Experimental evaluation on independent testing data confirmed that the optimized ResNet50v2 outperformed other architectures, achieving a perfect score of 1.0 in various performance measures. Thus, the optimized ResNet50v2 can be considered a reliable diagnostic model for automatically classifying PF-positive patients using chest CT images.

Summary: X-ray dark-field chest imaging allows for the diagnosis of pulmonary emphysema in patients with COPD by providing relevant information on the structural condition of lung parenchyma. This technique may offer a low radiation dose alternative to CT in COPD and potentially other lung disorders.

Summary: This study evaluates coronary artery disease (CAD) in atrial fibrillation (AF) patients requiring ablation using computed tomography coronary angiography (CTCA)-derived fractional flow reserve (FFR). The results showed similar prevalence of CAD in both the AF group and non-AF group, suggesting shared associated risk factors for CAD and AF.

Summary: This study aimed to harmonize arterial enhancement in coronary CT angiography (CTA) exams by implementing a patient-, contrast- and kV-tailored injection protocol. The results showed that by using a model based on patient's fat free mass, contrast agent concentration, and CT-scan tube voltage, the arterial enhancement among patients can be adjusted to a predefined target value.

Summary: The study aims to assess the influence of medial or lateral imaging plane inclination on the measurement of sulcus angle, trochlear depth, and facet asymmetry on transverse cross-sectional images. The results show that an 8-degree medial or lateral inclination does not significantly affect the typical parameters used for the assessment of trochlear dysplasia, but the measurement height has a significant impact.

Summary: In this study, the stent appearance in a novel Si-PCCT prototype was compared with a conventional EIDCT system, and it was found that Si-PCCT outperforms EIDCT in terms of stent appearance, blooming, and inter-stent visibility. Si-PCCT provides higher spatial resolution, leading to more accurate diameter measurements, reduced blooming, and improved inter-stent distinction.

Summary: Measuring muscle quantity and quality is important, but ultrasound has limited field of view. This study evaluated the reliability of extended-field-of-view ultrasound for measuring muscle quantity and quality in nine muscles. Results showed good to excellent intra-rater and inter-rater reliability for most muscle measurements.

Summary: This study compared the prognostic value of invasive coronary angiography (ICA) and coronary computed tomography angiography (CCTA) in predicting long-term vital prognosis post-revascularization in patients with coronary artery disease. The results showed that the SYNTAX score II 2020 (SS-2020) derived from both ICA and CCTA had similar predictive ability and could discriminate vital prognosis in high- and low-risk patients.

Summary: This study examined the effects of vessel morphology on computed tomography-derived fractional flow reserve in 1492 outpatients with suspected coronary artery disease. The results showed that, even with similar vessel length and plaque characteristics, there were significant differences in lumen volume and distal computed tomography-derived fractional flow reserve between two patients, indicating that computed tomography-derived fractional flow reserve depends not only on vessel length and plaque characteristics, but also on lumen volume and vessel morphology.
