Ultrasonography of the multifidus muscle in student circus artists with and without low back pain: a cross-sectional study

Author(s): Bianca Rossini

CONCLUSION: This study provided novel insights into LM characteristics in circus artists. Greater LM asymmetry was observed in artists with a history of low back pain. In accordance with previous studies in athletes, LM morphology and function were highly c ...

Deep reconstruction of high-quality ultrasound images from raw plane-wave data: A simulation and in vivo study

Author(s): Goudarzi S; Rivaz H;

This paper presents a novel beamforming approach based on deep learning to get closer to the ideal Point Spread Function (PSF) in Plane-Wave Imaging (PWI). The proposed approach is designed to reconstruct a high-quality version of Tissue Reflectivity Functi ...

Ultrasound Imaging Analysis of the Lumbar Multifidus Muscle Echo Intensity: Intra-Rater and Inter-Rater Reliability of a Novice and an Experienced Rater

Author(s): Fortin M; Rosenstein B; Levesque J; Nandlall N;

Background and Objectives: Ultrasound echo intensity (EI) of the lumbar multifidus muscle (LMM) could offer valuable insights regarding muscle quality in people with low back pain (LBP). However, whether the rater's experience noticeably influences the ...
