Stent appearance in a novel silicon-based photon-counting CT prototype: ex vivo phantom study in head-to-head comparison with conventional energy-integrating CT Vrije Universiteit Brussel
Methods: An ex vivo phantom was created, consisting of a 2% agar-water mixture, in which human-resected and stented arteries were individually embedded. Using similar technique parameters, helical scan data was acquired using a novel ...
Physical activity increases synovial fluid in ankle tendon sheaths Vrije Universiteit Brussel
Objectives: To compare the amount of fluid in synovial sheaths of the ankle before and after running. Our hypothesis was that this amount would increase and that the threshold for what is normally acceptable should be adjusted after physical activity. Methods: Twenty-one healthy volunteers (n = 42 ankles) ran for 40 min on a treadmill. They underwent 3 T MRI before and immediately after running using a dedicated ankle coil. The images were ...
Influence of medial and lateral imaging plane inclination on assessment of trochlear depth, sulcus angle, and facet asymmetry in the setting of trochlear anatomy Vrije Universiteit Brussel
PURPOSE: (1) to assess the influence of medial or lateral imaging plane inclination on the measurement of sulcus angle, trochlear depth, and facet asymmetry on transverse cross-sectional images. (2) to assess the effect of measurement level (height) on these respective parameters.
MATERIALS AND METHODS: Twenty dry femurs (9 left, 11 right) were imaged with CT. A 3D dataset was obtained from which axial images were reconstructed in the ...
T2-weighted turbo spin-echo magnetic resonance imaging of canine brain anatomy at 1.5T, 3T, and 7T field strengths Vrije Universiteit Brussel
Post-mortem T2 weighted images of canine heads were acquired at 1.5T, 3T, and7T. This study aimed to: 1) identify anatomical structures of the canine brain using an ultra-high-field MRI (7T) to help to facilitate their localization on high field MRI images (3T and 1.5T), where these structures may appear less well defined and delineated; and 2) evaluate the visibility of canine brain anatomical structures on 1.5T, 3T, and 7T MRI images for ...
Manual Lymphatic Drainage Increases the Number of Opened Lymphatic Pathways in Patients with Lower Limb Lymphedemas Vrije Universiteit Brussel
Feasibility and Tolerance of Fingertip Peripheral Arterial Tonometry Measurements in School-Aged Children Vrije Universiteit Brussel KU Leuven
Background: Assessment of the endothelial function of the microvasculature by peripheral arterial tonometry (PAT) has gained increasing popularity in pediatrics. Discomfort or experienced pain during fingertip PAT has only been studied in adolescents and adults. Methods: In 142 children (aged 4-11 years old), a fingertip PAT with a commercial device (EndoPAT 2000®) as well as a caliper and ultrasound examination of peripheral skinfolds were ...
Pronator quadratus repair after volar plate fixation in distal radial fractures Vrije Universiteit Brussel
The objective was to evaluate pronator quadratus (PQ) repair following volar plating of distal radial fractures on clinical and functional outcome, as well as flexor tendon friction, during the first 12 months in ideally positioned plates (Soong 0). Confounding factors like variation in plate positioning, anatomical consolidation of the fracture and associated lesions were excluded. Eighty patients were included with distal radius fractures ...
Pseudo-tear appearance of the Achilles tendon on MR imaging in normal volunteers Vrije Universiteit Brussel
PURPOSE: The aim of this study was to confirm our clinical observation that a pseudo-tear appearance of the Achilles tendon is commonly seen on MRI and is of no clinical relevance.
MATERIALS AND METHODS: Forty-one ankles were imaged on a 3 T MR system, and PD weighted images with fat saturation were obtained in three orthogonal planes (TR, 2969 ms; TE, 30 ms; NA, 2; slice thickness, 2.5 mm). Volunteer exclusion criteria were symptoms ...
Neuroanatomical Reconstruction of the Canine Visual Pathway Using Diffusion Tensor Imaging Vrije Universiteit Brussel
The first anatomical atlas of diffusion tensor imaging (DTI) of white matter pathways in the canine brain was published in 2013; however, the anatomical orientation of the entire visual pathway in the canine brain, from the retina to the cortex, has not yet been studied using DTI. In the present study, 3T DTI magnetic resonance (MR) images of three dogs euthanized for reasons other than neurological disorders were obtained. The process of ...
