Whole-body PET imaging is often hindered by respiratory motion during acquisition, causing significant degradation in the quality of reconstructed activity images. An additional challenge in PET/CT imaging arises from the respiratory phase mismatch between CT-based attenuation correction and PET acquisition, leading to attenuation artifacts. To address these issues, we propose two new, purely data-driven methods for the joint estimation of activity, attenuation, and motion in respiratory self-gated TOF PET.

In this work, we compare the performance of commonly used reference-based and reference-free image quality metrics on a unique dataset with real motion artifacts. We further analyze the image quality metrics' robustness to typical pre-processing techniques.

Medial capsulorrhaphy is an important step in hallux valgus correction surgery; however, studies on this technique are limited. This study aimed to evaluate the viability and efficacy of modified medial capsulorrhaphy using figure-of-eight sutures for hallux valgus compared to the conventional technique. Retrospective analysis was performed on patients with hallux valgus, comparing a group receiving standard longitudinal capsulorrhaphy (Group 1) and a group that underwent modified capsulorrhaphy using figure-of-eight sutures (Group 2).

Purpose: To evaluate the clinical outcomes of a new FDA approved toric aspheric hydrophobic acrylic intraocular lens.
Patients And Methods: This is a single surgeon, single-arm, on-label, non-randomized, prospective observational study. Thirty patients underwent bilateral cataract surgery (60 eyes) with placement of a Clareon™ Toric IOL in each eye.
Unlabelled: Cytoplasmic proteins must recruit to membranes to function in processes such as endocytosis and cell division. Many of these proteins recognize not only the chemical structure of the membrane lipids, but the curvature of the surface, binding more strongly to more highly curved surfaces, or 'curvature sensing'. Curvature sensing by amphipathic helices is known to vary with membrane bending rigidity, but changes to lipid composition can simultaneously alter membrane thickness, spontaneous curvature, and leaflet symmetry, thus far preventing a systematic characterization of lipid composition on such curvature sensing through either experiment or simulation.
