Summary: This study assessed the relevance of using multi-positional MRI to identify cranio-vertebral junction instability in pediatric patients with CVJ anomalies. It identified specific morphometric parameters and cutoff values that could serve as objective mMRI criteria. Qualitative analysis also found correlations between instability and specific C2 anomalies.

Summary: Multi-positional MRI can help identify dynamic cord compressive lesions in CDS patients. Higher eC27A, e-nC27A values, and smaller C7 slope indicate increased likelihood of cervical dynamic stenosis. Therefore, we recommend multi-positional MRI before surgery, especially when a patient's e-nC27A is greater than 15.4 degrees.

Summary: A new method for modeling the right ventricle surface using multiple 2D contours, incorporating information from multiple cross-sectional images into the same model, showed significantly lower segmentation error compared to conventional 2D ASM, especially at the apical slices. The proposed method also had a shorter computation time compared to the previously reported 3D ASM formulation.

Summary: The purpose of this study is to use a statistical shape model and an active shape model for globe segmentation and to differentiate between normal globes and globe injuries. The results show that the active shape model segmentation is consistent with manual segmentation, and the segmented globes with injuries differ from normal globes in terms of structural deformation.

Summary: This study used a practical positional MRI protocol to evaluate tibiofemoral translation and rotation in normal and injured knees. The results showed that ACL tear knees exhibited increased tibial anterior translation and decreased external rotation compared to normal knees. Multidirectional malalignment was more common in ACL tear knees.

Summary: This article proposes a new multi-objective optimization method for reactive power dispatch, considering the differences in load levels and the uncertainty of load models and demands. To solve the problem effectively, an optimization approach based on modified grey wolf optimizer and multi-level Pareto analysis is used, along with a multi-criteria decision-making method to find the final suitable answer. The proposed method's performance is validated using the IEEE 69-bus distribution network as a test system.

Summary: This paper introduces the advantages and issues of magnetic bearings and presents the design of a six-pole AC active magnetic bearing. The mathematical model of the active magnetic bearing is established using the Maxwell tensor method. A fuzzy active disturbance rejection control method is designed based on fuzzy control and ADRC theory. The experimental results demonstrate the rationality and stability of the designed bearing.

Summary: In this study, new models considering the shape and stacking patterns of sediment particles were established and verified. The octahedral model, plate-shape model, and average values of the four models were found to be accurate in predicting the effective thermal conductivity (ETC) of hydrate-bearing sediments. The effects of porosity, hydrate saturation, and intrinsic thermal conductivity of sediment particles on ETC were also analyzed.

Summary: In this study, the diagnostic and treatment-monitoring potential of sodium (Na-23) MRI in breast cancer was demonstrated. The researchers found elevated sodium concentration in tumor regions compared to non-tumor regions, and combining Na-23 MRI with other imaging measurements improved the accuracy of tumor classification. This novel MRI method also showed superior sensitivity in assessing treatment response compared to traditional methods.

Summary: The study found that positron emission tomography-computerised tomography is more accurate than dynamic contrast-enhanced computerised tomography in characterising solitary pulmonary nodules. The combination of maximum standardised uptake value and peak enhancement had the highest accuracy with a slight increase in costs. The study also suggested that a combination of positron emission tomography and dynamic contrast-enhanced computerised tomography may be considered for better management of small cancers.

Summary: This paper proposes a novel framework called MorphHR for mammogram classification, which introduces a new transfer learning scheme and integrates function-preserving transformations to improve classification performance. The proposed approach allows for modification of both the last few layers and the first layers, and is scalable to hardware. Experimental results demonstrate the superiority of the proposed method.

Summary: This study examined the genetic architecture of cam morphology using the alpha angle (AA) as a measure and found a bidirectional relationship between AA and hip osteoarthritis (OA). The results suggest that a genetic predisposition to hip OA contributes to the relationship between hip OA and cam morphology, indicating the importance of genetic factors in the development of these conditions.

Summary: This study evaluated the performance of artificial intelligence (AI) in the interpretation of digital mammography and digital breast tomosynthesis (DBT). The results showed that standalone AI performed as well as or better than radiologists in digital mammography, but there were insufficient studies to assess its performance in DBT interpretation.

Summary: This study explores the relationship between indices of hypoxia and vascular function in ER + breast cancer using [F-18]-FMISO PET/MRI and immunohistochemical markers. The results indicate that hypoxia is associated with increased CAIX expression, reduced microvessel density, and smaller vessel diameters in ER + breast cancer, further confirming the link between inadequate vascularity and hypoxia in this type of cancer.

Summary: Recent developments in musculoskeletal modeling have focused on model customization. Personalization of the spine profile may affect estimates of spinal loading and stability. This study investigates the biomechanical consequences of changes in the spinal profile and finds that personalizing the spine profile has medium to large effects on trunk muscle forces and negligible to small effects on spinal loading and stability.

Summary: Exercise therapy fails in about 25.0% of cases for individuals with rotator cuff tears, and one reason for this failure may be the inability to strengthen and balance the muscle forces that keep the humeral head in the correct position. This study developed computational musculoskeletal models to compare the net muscle force before and after exercise therapy between successfully and unsuccessfully treated patients. The study found that unsuccessfully treated patients had less inferiorly oriented net muscle forces, which may increase the risk of impingement.

Summary: This study aimed to explore the intra-foot biomechanical differences among individuals with chronic ankle instability (CAI), copers, and healthy individuals during dynamic tasks. The study found that copers and CAI individuals had smaller dorsiflexion angles and copers presented a more eversion position compared to healthy participants. Copers also had greater dorsiflexion angles in the metatarsophalangeal joint and more inversion moments in the subtalar joint during certain tasks. These findings can help in designing interventions to restore ankle joint functions in CAI individuals.
