Background Context: Preoperative imaging for lumbar spine surgery often includes magnetic resonance imaging (MRI) for soft tissues and computer tomography (CT) for bony detail. While CT scans expose patients to ionizing radiation, whereas MRI scans do not. Emerging MRI techniques allow CT-like 3-dimensional (3D) visualization of bony structures, potentially removing the need for ionizing radiation from CT scans.

Article Synopsis
- The study examines the prevalence of abnormalities in the humeral head of asymptomatic collegiate baseball pitchers using ultrasonography, comparing it to a control group of non-overhead athletes.
- Findings reveal that 76% of pitchers have abnormalities in their throwing shoulder, significantly higher than the control group's shoulders.
- The study utilized various imaging methods and motion measurements to assess these abnormalities, highlighting the importance of monitoring even asymptomatic athletes in overhead sports.
A Novel Evaluation for Vertebral Artery Course Using 3D Magnetic Resonance Imaging with Computed Tomography -like Bone Contrast and Magnetic Resonance Angiography: A Proof of Concept Study.

Department of Orthopaedic Surgery, Chiba University Graduate School of Medicine, Chiba, Japan.
Objective: Vertebral artery (VA) injury poses a significant risk in cervical spine surgery, necessitating accurate preoperative assessment. This study aims to introduce and validate a novel approach that combines the Fast field echo that resembles a computed tomography using restricted echo spacing (FRACTURE) sequence with Time of Flight (TOF) Magnetic Resonance Angiography (MRA) for comprehensive evaluation of VA courses in the cervical spine.

Introduction: Precision monitoring maturity in climacteric fruits like tomato is crucial for minimising losses within the food supply chain and enhancing pre- and post-harvest production and utilisation.
Objectives: This paper introduces an approach to analyse the precision maturation of tomato using hyperspectral tomography-like.
Methods: A novel bi-directional spectral reconstruction method is presented, leveraging visible to near-infrared (Vis-NIR) information gathered from tomato spectra and their internal tissues (skin, pulp, and seeds).
Energy Landscapes for Lithium Incorporation and Diffusion in Multidomain Silicon Suboxide Anode Materials.

In-depth understanding of the lithium interaction characteristics within multidomain silicon suboxide is indispensable for optimizing the electrochemical performance of silicon suboxide anode materials for lithium-ion batteries. In this study, we investigate the domain-dependent thermodynamic and kinetic properties of lithium atoms within systematically designed multidomain silicon suboxide models composed of Si, SiO, and Si/SiO interface by performing a series of computational simulations combined with a unique tomography-like sampling scheme. We find that the Si/SiO interfacial region exhibits preferential thermodynamics and kinetics for lithiation and can serve as a critical lithium transport channel during charge-discharge cycles, while the SiO domain is likely to be excluded from lithiation due to its high resistance to lithium diffusion.
