    3D imaging of internal structures of skeletal muscle with an ultrathin side-viewing optical needle probe

    Evaluation of degradation in the structure of skeletal muscle is important for the assessment or diagnosis of many myopathies, such as Duchenne muscular dystrophy. Histological analysis is the gold standard to evaluate such degradation but requires excision and fixation of the tissue. This is undesirably invasive in patients and precludes longitudinal study of disease progression in patients or animal models. Optical coherence tomography (OCT) is a high-resolution (∼10μm) imaging modality capable of visualising muscle structure and the morphological changes in muscular dystrophy. However, because of the limited image penetration of OCT (∼2mm), previous studies have been restricted to imaging ...
