Magnetic resonance imaging for Musculoskeletal imaging plays a vital role in the early detection of various abnormalities. New array systems designed explicitly for Musculoskeletal imaging at Ultra-high field strengths are being developed rapidly. In this study, we propose a new 8-channel array system consisting of High-permittivity dielectric material-coated half-wave dipole antennas for knee imaging at Ultra-high field 7 Tesla.

Intracranial hemorrhage (ICH) is bleeding within the cranium and occurs within the brain tissue, ventricles, and intracranial space. Hematoma expansion following an ICH has been related to increased mortality and morbidity inpatients. To detect ICH patients at risk, machine learning models can be used to predict whether or not hematoma expansion will occur. This study aims to assess the feasibility of machine learning prediction models using a radiomics approach. The highest sensitivity results indicated as 95% confidence intervals are 0.68 ± 0.004 and 0.72 ± 0.004, were achieved by support vector machine and logistic regression classifier models, respectively.

This study presents a method for the B1 field flattening and length control of the half-wave dipole antenna for MR imaging with discrete dielectric material coating. To demonstrate this method, we designed a half-wave dipole antenna to operate at 300MHz, including coating the ends of the dipole conductors with a high dielectric material, serving as a way to control the dipole length and electromagnetic field distribution. We also compare the proposed technique with the conventional half-wave dipole antenna and show how the new technique effectively tunes the shorter half-wave dipole antennas at specific frequencies and produces efficient field distributions.

We demonstrate that non-rigid deformations of, e.g., the mouth introduce bias in the vNav-based detection of brain motion, which causes artifacts. We present real-time brain extraction for vNavs and show that these artifacts can be removed by brain-masked registration.
