Summary: Monitoring plastic ingestion by marine wildlife is crucial for understanding the extent of plastic pollution and its impact on species and ecosystems. Current detection methods are slow and invasive, limiting the number of animals that can be screened. This study explores the use of MRI as a rapid and non-invasive method to detect plastic ingestion. The results show that MRI and NMR can directly or indirectly detect plastic in the digestive system of animals, with distinctive NMR signal characteristics for each type of plastic. While commercial MRI technology is not suitable for field use, existing single-sided MRI research systems could be adapted for monitoring wildlife outside the laboratory.

Summary: This article presents a novel magnetic tensor sensor (MTS) for tracing human joint trajectory and a physics-based measurement model implemented on an artificial neural network (ANN). Experimental results show that the system can calibrate the sensor parameters, consider the environmental magnetic effects, and be trained with different data.

Summary: This study aims to develop a cyclic gastric contractile motion prediction model for real-time management during radiation therapy. The model extracts gastric contraction motion phases, estimates real-time sampled data, and predicts future gastric motion accurately. The results show that the model has high prediction performance and has the potential for clinical implementation.

Summary: The present study evaluates a multisite ultrasonographic protocol for measuring muscle thickness (MT) and finds that it has good consistency and correlation with gold-standard measurements of muscle volume (MV) obtained from MRI. Therefore, ultrasound measurement of MT could serve as a feasible alternative, especially in terms of availability and time consumption.

Summary: This longitudinal study on mountain ultramarathon athletes' quadriceps revealed physiological changes related to inflammation and metabolic responses after extreme endurance races. Quantitative MRI was proven effective in detecting these changes, with different muscle heads showing varied recovery processes.

Summary: The study aimed to evaluate the diagnostic accuracy of MRI in cases of joint effusion and found a significant correlation between the presence of joint effusion detected by MRI and clinical and arthroscopic findings. Pain was significantly related to the presence of effusion, Wilkes advanced stages, synovitis, and adhesions.

Summary: An hierarchical motion model was developed to characterize the complex motion patterns of abdominal organs, revealing significant variations in motion modes and configurations. The study demonstrated the potential applications of hierarchical motion models in radiotherapy for improving dose delivery estimation, guiding margin creation, and supporting advanced decision-making.

Summary: Magnetic resonance diffusion kurtosis imaging (DKI) is an emerging MRI technique that can reflect microstructural changes in tissue and has shown greater sensitivity for diagnosis and treatment planning of musculoskeletal diseases. It is also an important auxiliary examination for evaluating the motor function of the musculoskeletal system.

Summary: The article presents a retrospective joint motion correction and reconstruction scheme to reduce the impact of subject motion on MRI images. The scheme leverages uncorrupted reconstructions to post-process contrasts most affected by motion, assuming a shared underlying anatomy. Rigid motion is considered, and classical motion correction schemes are combined with weighted total-variation regularization.

Summary: This review focuses on the technical advances in reducing metal artifacts in orthopedic surgery, including digital tomosynthesis, computed tomography, and magnetic resonance imaging. Despite the introduction of new diagnostic imaging methods and technologies, metal artifacts have not yet been completely eliminated. Further research is needed to develop algorithms and techniques for reducing metal artifacts, as well as the combination of different imaging modalities to further reduce them.

Summary: Anterior cruciate ligament injury and reconstruction can affect cartilage thickness profiles in the knee, with differences observed between males and females in terms of the locations and magnitudes of changes. Changes in cartilage thickness may indicate early signs of posttraumatic osteoarthritis.

Summary: Existing wearables-based algorithms for analyzing muscle and joint mechanics during free-living activities are hindered by complex sensor arrays. In this study, a hybrid method using inertial sensors and electromyography (EMG)-driven muscle contraction simulation is proposed to characterize knee joint and muscle mechanics during walking. Machine learning is used to reduce the number of required sensors by mapping a subset of muscle excitations. The proposed technique showed promising results in estimating knee flexion moment, individual muscle moment, and work during gait.

Summary: This study investigated the hip joint mechanics in patients with cam-type femoroacetabular impingement (FAI) syndrome. The results showed that individuals with cam FAI syndrome had larger changes in bone-to-bone distance during walking activities, which could potentially lead to pain, tissue damage, and osteoarthritis.

Summary: This study quantified the effects of interpolation and intra-user variability on kinematic and arthrokinematic measurements using model-based tracking (MBT), and compared them to a gold standard radiostereometric analysis (RSA). Results showed that interpolation had a minimal effect on kinematic measurements, while intra-user variability had a larger impact. However, interpolation could still be used without sacrificing measurement accuracy for arthrokinematic outcomes.
