Summary: The study found a significant positive correlation between lower leg muscle cross-sectional area measured by pQCT and total LSTM in children, suggesting it could be a predictor of low LSTM. The results showed that pQCT measurement of lower leg MCSA could help identify children with low LSTM.

Summary: In this study, the authors assessed the diagnostic discordance between lumbar osteoporosis detected by QCT and DXA, and evaluated their predictive performance for prevalent vertebral fracture. The results showed that in older patients undergoing spinal surgery, QCT-vBMD is more helpful than DXA in terms of osteoporosis detection rate and prediction of patients with prevalent VFs.

Summary: Quantifying fat within skeletal muscle using DECT is feasible and reliable, with excellent correlations between DECT-FF and MR-FF, DECT VNC HU and MR-FF, and DECT-FF and DECT VNC HU. DECT muscle analysis offers a new approach to determine muscle quality, crucial for diagnosing and monitoring sarcopenia as a comorbidity associated with poor clinical outcomes.

Summary: The study found that different body fat depots were associated with the development of new-onset atrial fibrillation (AF). Total fat mass and abdominal fat mass were independently associated with AF, while the ratio of abdominal fat to hip fat showed an inverse association. These findings provide new insights into the pathogenesis and prevention of AF.

Summary: This article discusses the technical principles and clinical applications of dual-energy computed tomography (DECT) in cardiothoracic imaging, with a focus on current developments and techniques. Different vendors have developed distinct hardware and software approaches for generating multi-energy datasets and various DECT applications, which have been clinically investigated in different fields. Recent literature reports have highlighted the benefits of DECT in oncology, trauma and emergency radiology, musculoskeletal imaging, and cardiovascular imaging. State-of-the-art applications such as virtual monoenergetic imaging, material decomposition, perfused blood volume imaging, and virtual non-contrast imaging have the potential to significantly improve cardiothoracic CT image workflows and enhance diagnostic accuracy and patient safety.

Summary: Quantitative parameters of DECT, specifically AIF and lambda (Hu), show good performance in distinguishing tumor active area, adjacent normal tissue, and tumor necrotic area in HCC patients treated by TACE.

Summary: This study found that the quantity of muscle mass in the lower extremities is associated with the severity of vascular stenosis in PAD patients. The muscle mass in the legs of PAD patients is lower and changes earlier than in the abdomen. Age, gender, BMI, and PAD are factors associated with low muscle mass.

Summary: The study evaluated the performance of three different decalcification solutions in human bone through direct measurement using DEXA and CT scans. Results showed that RBD solution had the fastest decalcification rate and was able to fully decalcify bone slices after 77 hours. Hydrochloric-acid based solutions appeared to be preferable for rapid dissolution of calcium hydroxyapatite compared to other solutions.

Summary: Emerging evidence suggests that leanness and good metabolic health markers may predict larger increases in LDL cholesterol (LDL-C) in response to carbohydrate restriction. Specifically, a recent cohort study identified a subgroup of individuals, known as Lean Mass Hyper-Responders (LMHR), who exhibit exceptional increases in LDL-C despite low triglycerides and high HDL-C levels. This case study presents the results of one subject, LM, who experienced a significant increase in LDL-C after adopting a ketogenic diet for ulcerative colitis management. The findings suggest that the LMHR phenotype is not dependent on saturated fat intake but may be inversely associated with changes in BMI. Interestingly, computed tomography angiography revealed no evidence of plaque formation in LM after more than 2 years of hypercholesterolemia.

Summary: This study compared the image characteristics of a first-generation dual-source photon-counting computed tomography (PCCT) and a dual-source dual-energy CT (DECT) scanner at ultra-low radiation dose levels. The results showed that PCCT had high precision in Hounsfield unit (HU) measurements at various radiation dose levels, outperforming DECT at low doses and significantly reducing electronic background noise.

Summary: The study found that in people with obesity, the reliability of estimating FM using multifrequency BIA is high, and for ALM estimation, BIA showed good correlation with DXA, but it tended to overestimate ALM when proprietary equations were used.

Summary: This study aims to evaluate the accuracy of a new method that combines CT imaging data with automatic software and artificial intelligence to estimate body composition in patients with obesity. The results show that this new method has high accuracy in estimating body composition in obese patients.
