Ultrasound Biomarkers for Sarcopenia: What Can We Tell So Far?
Semin Musculoskelet Radiol 2020; 24: 181-193 DOI: 10.1055/s-0039-3402745Sarcopenia is a disease characterized by decreased skeletal muscle mass, strength, and loss of function that can impair quality of life and increase physical disability, adverse metabolic effects, and mortality. This review familiarizes the reader with ultrasound (US)-based biomarkers for sarcopenia with a discussion of these topics: why assessing sarcopenia is relevant for radiologists, how to evaluate muscle structure with US, the current challenges or pitfalls of these biomarkers, and the implications of all the available evidence. It summarizes the...

Peripheral Nerves: Not Only Cross-sectional Area in the Era of Radiomics
Semin Musculoskelet Radiol 2020; 24: 175-180 DOI: 10.1055/s-0040-1701629The peripheral nervous system is increasingly being investigated using medical imaging as a complement or in association with electrodiagnostics tests. The application of imaging techniques, such as ultrasound (US) and magnetic resonance imaging (MRI), allows detailed visualization of the peripheral nervous system. According to the European Society of Musculoskeletal Radiology, the use of US for nerve evaluation is strongly encouraged. In addition, the role of US is further enhanced by the wide application of US-guided techniques to diagnose or to trea...

The Role of Ultrasound in the Diagnosis of Soft Tissue Tumors
Semin Musculoskelet Radiol 2020; 24: 135-155 DOI: 10.1055/s-0039-3402060The vast majority of soft tissue masses are benign. Benign lesions such as superficial lipomas and ganglia are by far the most common soft tissue masses and can be readily identified and excluded on ultrasound (US). US is an ideal triaging tool for superficial soft tissue masses. Compared with magnetic resonance imaging (MRI), High-resolution US is inexpensive, readily available, well tolerated, and safe. It also allows the radiologist to interact with the patient as a clinician. In this review, we describe and illustrate the lesions with typical (diag...

Weight-bearing CT Technology in Musculoskeletal Pathologies of the Lower Limbs: Techniques, Initial Applications, and Preliminary Combinations with Gait-Analysis Measurements at the Istituto Ortopedico Rizzoli
This article discusses the initial experience over a few studies in progress at an orthopaedic center.

However, conventional supine MRI findings often correlate poorly with clinical findings. Some patients experience accentuated back pain in the weight-bearing position. Therefore, supine MRI may underestimate the severity of degenerative spine findings.

Weight-bearing Imaging in Adolescent Idiopathic Scoliosis
This article reviews the weight-bearing imaging methods in the diagnosis and monitoring of patients with adolescent idiopathic scoliosis (AIS), a three-dimensional (3D) deformity of the spine with unknown etiology. The apical vertebrae in AIS rotate away from the midline in a complex 3D pattern that formerly could only be appreciated by computed tomography (CT). Despite its superb anatomical delineation, CT is not ideal due to high radiation and scanning in either the supine or prone position; hence the full effect of gravity on the spinal curvature cannot be assessed.

Semin Musculoskelet Radiol 2019; 23: 429-435 DOI: 10.1055/s-0039-1693488Shoulder ultrasound is a commonly performed imaging study that can accurately determine the presence of rotator cuff tendinosis and tears, as well as subacromial-subdeltoid bursal and long head of biceps tendon pathology. High accuracy depends on an awareness of imaging pitfalls that can be encountered and lead to over- or underdiagnosis of rotator cuff pathology. Ten common pitfalls of rotator cuff ultrasound scanning are presented along with ways to avoid these pitfalls. [...] Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.Arti...

Top-Ten Tips for Ultrasound-Guided Joint Injection
Semin Musculoskelet Radiol 2019; 23: 419-428 DOI: 10.1055/s-0039-1694755Ultrasound-guided joint injection is more accurate than palpation-guided injection and performed more frequently. Joint injection is helpful for therapeutic and diagnostic purposes as well as for injecting contrast agents for magnetic resonance imaging or computed tomography arthrography. Ultrasound-guided joint injection helps ensure intra-articular injection and minimizes injury to para-articular soft tissues.

Top-Ten Tips for Imaging the Brachial Plexus with Ultrasound and MRI
Semin Musculoskelet Radiol 2019; 23: 405-418 DOI: 10.1055/s-0039-1694753When it comes to examining the brachial plexus, ultrasound (US) and magnetic resonance imaging (MRI) are complementary investigations. US is well placed for screening most extraforaminal pathologies, whereas MRI is more sensitive and accurate for specific clinical indications. For example, MRI is probably the preferred technique for assessment of trauma because it enables a thorough evaluation of both the intraspinal and extraspinal elements, although US can depict extraforaminal neural injury with a high level of accuracy. Conversely, US is probably t...

Top-Ten Tips for Effective Imaging of Axial Spondyloarthritis
Semin Musculoskelet Radiol 2019; 23: 376-391 DOI: 10.1055/s-0039-1693661Axial spondyloarthritis (axSpA) is a chronic inflammatory condition that encompasses ankylosing spondylitis as well as nonradiographic axSpA and can lead to chronic pain, structural damage, and disability. The disease is strongly associated with the presence of human leukocyte antigen-B27. Early diagnosis of axSpA is significant due to new treatment regimens leading to reduction of inflammation and potentially delaying disease progression. Imaging of the sacroiliac joints and the spine plays an important role in the early diagnosis of spondyloarthritis...

Top-Ten Tips for Imaging Groin Injury in Athletes
This article highlights these key aspects of athletic groin injury with tips on anatomy, potential abnormalities, acronyms, and imaging appearances in this complex but common and potentially incapacitating entity. Many clinical and radiologic terms are in use such as cleft, enthesitis, plate injury, or defect that can cause confusion, and thus anatomical descriptions are preferable.Detailed clinical assessment is necessary but remains challenging because of the nonspecific presentations. Imaging, and in particular magnetic resonance imaging, plays an essential role in the evaluation process. But only when the two are used ...
