Summary: Soil structure plays a crucial role in root architectural development and plant yield. This study explores how different aggregate sizes influence early root growth in wheat plants. Results indicate that smaller aggregates promote increased lateral root growth, while larger aggregates induce more seminal root axes in wheat seedlings.

Summary: This study utilized a state-of-the-art non-destructive 3D method, including multimodal neutron and X-ray tomography, to observe the characteristics of corrosion products in two concrete samples. The research aimed to investigate the potential benefits of this technique for reinforced concrete structures, providing quantitative and qualitative data on the corrosion process.

Summary: XCT is a valid method for quantifying surface metrology of parts, but small changes in capture settings can affect the surface data extracted. This study investigates the effects of refocusing on the extracted surface data and compares it to the variation resulting from filament changes.

Summary: This study investigated the early-age drying and plastic shrinkage of mortars using bimodal neutron/X-ray computed tomography and found that the application of a paraffin-based curing compound can substantially reduce evaporation rate and vertical displacement rate. The results provide new insights into the mechanisms of plastic shrinkage and the effects of curing compounds.

Summary: The study evaluated the impact of breathing state on the accuracy of a 3D camera for body contour detection and patient positioning in thoracic CT. Results showed that acquiring camera images and subsequent CT scans in the same breathing state leads to accurate and precise patient positioning. It is recommended to obtain expiratory planning images when performing a thoracic CT scan in both inspiratory and expiratory breathing states.

Summary: This study found that introducing a template for radiological reporting of NECT in the primary care diagnostic work up of cognitive impairment significantly increased the mentioning of MTA, WMC, and GCA in radiology reports, as well as the percentage of reports where all parameters were mentioned. The findings suggest that using contextual radiological assessment with VRS could increase the reporting frequency of radiology findings in the diagnostic work up of cognitive impairment, but compliance with templates may be difficult to endorse.

Summary: This paper introduces Livermore Tomography Tools (LTT), a customizable scientific software package for computed tomography (CT) research. LTT is capable of processing various CT data accurately and rapidly, with support for multiple CPUs and GPUs. It offers 88 algorithms for pre-processing, reconstruction, post-processing, and simulation, and supports different scanner geometries. Several applications demonstrate LTT's accuracy, speed, and flexibility compared to other solutions.

Summary: The study aimed to identify CT-acquisition parameters affecting radiomics variability and develop a post-acquisition CT-image correction method to improve radiomics classification accuracy in phantom and clinical applications. Results showed that post-acquisition processing of CT images can reduce radiomics variability and improve classification accuracy.

Summary: Objective body composition assessment derived from cross-sectional imaging has shown promising results as a prognostic biomarker in several tumor entities. In this study, we aimed to analyze the role of low skeletal muscle mass and fat areas for prognosis of dose-limiting toxicity and treatment response in patients with primary central nervous system lymphoma.

Summary: This study aimed to explore the value of preoperative contrast-enhanced CT (CECT) features and clinical data in predicting microvascular invasion (MVI) in combined hepatocellular-cholangiocarcinoma (cHCC-CCA) patients. The preoperative imaging features and clinical data were found to be significantly different between the MVI-positive and MVI-negative groups. Multivariable logistic regression analysis showed that arterial phase peritumoral enhancement and high serum PIVKA-II level were independent predictors associated with MVI in cHCC-CCA. The combination of these predictors had high sensitivity in predicting MVI.

Summary: In this study comparing PCD-CT and EID-CT in mouse specimens, PCD-CT demonstrated lower image noise, higher SNR, and better edge sharpness compared to EID-CT. Radiologists consistently preferred PCD-CT for visualizing bone details, even in SNR-matched pairs.

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 aims to detect stochastic defects in laser powder bed fusion (LPBF) parts through in-situ monitoring and X-ray computed tomography (XCT) validation. An in-situ optical tomography (OT) method successfully detected 79% of lack of fusion defects, particularly large ones, in Hastelloy X specimens. This study demonstrates the applicability of in-situ monitoring for indirect detection of stochastic lack of fusion in LPBF.
