“…MR spectroscopy is a promising method for evaluating metabolic activities and biochemical composition. Detecting different signals from different molecules may help to assess the level of water, inorganic phosphate or adenosine triphosphate [ 36 ]. This method is used mostly for muscles, and application in tendons is technically challenging because of short T2 time.…”

Highlights Presence of normal septation between subtendons may mimic an intrasubstance tear. MRI is superior to ultrasound in detection of partial tears. Ultrasound is as useful as MRI in detection of tendinopathy and full-thickness tears. Kager's fat pad is involved in infection more than in postoperative changes. The Achilles tendon xanthoma has a higher signal on T1- and T2-weighted sequences.

“…29 The DTI approach is able to differentiate between functionally different muscles in the same body region as well as differentiate between injured and uninjured muscle, based on their water diffusive properties. [30][31][32] Using fiber tracking, a method that aligns directionality from the primary eigenvectors for each voxel, DTI has also been shown to differentiate muscle fiber orientation and determine resultant force vectors of muscular components in the quadriceps. 33 Previous studies have indicated that following muscular injury, fractional anisotropy (FA) values decreased, resulting from increased isotropic diffusion in the region (the result of torn muscle fibers and reduced restricted diffusion of water), and the apparent diffusion coefficient (ADC) values increased, due also to reduced restricted diffusion within that area.…”

The most common cause of chronic musculoskeletal pain is chronic myofascial pain syndrome (MPS). MPS often presents with increased muscle stiffness, and the myofascial trigger point (MTrP). Imaging modalities have been used to identify the MTrP, but their role in the detection and diagnosis of MPS remains unclear. The purpose of this review was to identify evidence in literature for the use of imaging in the role of classifying and explaining the physiology of MTrPs. Since few imaging techniques have been performed on MTrPs, we explored the imaging techniques that can effectively image complex skeletal muscle microstructure, and how they could be used. As part of a scoping review, we conducted a systematic search from three medical databases (CINAHL, EMBASE and MEDLINE) from year to year to analyze past MTrP imaging, as well as analyzing imaging techniques performed on the microstructure of muscle. Previously, ultrasound has been used to differentiate active, latent MTrPs, but these studies do not adequately address their underlying anatomical structure. MRI remains the standard method of imaging skeletal muscle. The existing MRI literature suggests that the DTI technique can quantify muscle injury, strain, and structure. However, theoretically, HARDI and DKI techniques seem to provide more information for complex structural areas, although these modalities have a disadvantage of longer scan times and have not been widely used on skeletal muscle. Our review suggests that DTI is the most effective imaging modality that has been used to define the microstructure of muscle and hence, could be optimal to image the MTrP. HARDI and DKI are techniques with theoretical potential for analysis of muscle, which may provide more detailed information representative of finer muscle structural features. Future research utilizing MRI techniques to image muscle are necessary to provide a more robust means of imaging skeletal muscle and the MTrP.

“…Being extremely sensitive for the presence of bone marrow and soft tissue oedema, MRI can identify the 'active cause' of pain. 4 This is especially helpful for patients with several findings on a scan. Technological advances have enabled three-dimensional isotropic acquisitions, resulting in high spatial resolution and generation of high-quality multiplanar reformats.…”
