Objectives: Photon-counting detector CT (PCD-CT) is expected to substantially improve and expand CT-imaging applicability due to its intrinsic spectral capabilities, increased spatial resolution, reduced electronic noise, and improved image contrast. The current study aim is to evaluate PCD-CT efficacy in characterizing bullets based on their dimensions, shape, and material composition.
Materials And Methods: This is an observational phantom study examining 11 unfired, intact bullets of various common calibers, placed in ballistic gelatin.
Multienergy cardiovascular computed tomography (CT) imaging can be defined as data acquisition at two (dual-energy) or multiple x-ray energies. Multienergy cardiovascular CT imaging provides additional qualitative and quantitative information such as material maps or virtual monoenergetic images, which are supposed to further improve the quality and diagnostic yield of CT. Recently introduced photon-counting detector CT scanners further address some of the challenges and limitations of previous, conventional CT machines, hereby enhancing and extending the applications of CT for cardiovascular imaging.

Acute limb ischemia (ALI) has been reported when the femoral artery was accessed, and it was associated with higher mortality in patients on extracorporeal membrane oxygenation (ECMO). However, prior studies were limited by small sample size and the lack of long-term follow-up.

Materials And Methods: This institutional review board-approved retrospective study included 83 subjects (49.4% male, aged 62.
Article Synopsis
- - The study examines the fibers from tucum, a palm species from the Atlantic Forest, and highlights their characteristics for potential uses in textiles and engineering applications.
- - Techniques like SEM, FTIR, and tensile strength tests show that tucum fibers have high tensile strength, good dye affinity, and are comparable to cotton and linen.
- - The findings suggest that tucum fibers are a renewable and sustainable material suitable for manufacturing high-quality products while promoting waste valorization.
