... from the radiograph unit and uploaded for viewing on a dedicated server. Musculoskeletal and chest radiologists reviewed rejected and repeat images in their timed sequence, in addition to the studies' remaining images. Radiologists answered questions regarding the added value of repeat images.The reviewing radiologist agreed with the reason for rejection for 64.2% of musculoskeletal and 60.9% of chest radiographs.
This study systematically summarizes quantitative imaging biomarker research in non-traumatic neck and shoulder musculoskeletal disorders (MSDs. There were two research questions: 1) Are there quantitative imaging biomarkers associated with the presence of neck and shoulder MSDs. 2) Are there quantitative imaging biomarkers associated with the severity of neck and shoulder MSDs.

... to highlight a variety of different tissue types and anatomic structures. In the following pictorial essay, we provide a number of clinical examples of the use of CR in musculoskeletalimaging, including the evaluation of complex fractures, the delineation of the relationship of fractures to adjacent vasculature and overlying soft tissues, and the visualization of vascular and soft tissue injuries.
PURPOSE: The purpose of this study was to determine the extent and severity of musculoskeletal discomfort in radiologists using a standardized tool, the Cornell Musculoskeletal Discomfort Questionnaire (CMDQ). In addition, we evaluated the influence of demographic factors on the frequency of symptoms, degree of discomfort, interference of symptoms with ability to work, and overall pain.
METHODS: The CMDQ was distributed via an anonymous link to all radiology trainees and faculty at our institution. The questionnaire assessed frequency and location of pain, severity of symptoms, and degree to which discomfort interfered with work. In addition, demographic data were collected.
RESULTS: The survey was completed by 99 radiologists (39% response rate). The majority (80%) of respondents spent greater than 7 hours per workday at a diagnostic workstation. The neck (66%), lower back (61%), upper back (43%), right shoulder (36%), and right wrist (33%) were the areas where radiologists most frequently reported ache, pain, or discomfort at least once per week. More than 7 hours per day at a computer workstation was significantly associated with higher total pain.
CONCLUSIONS: Musculoskeletal discomfort in the week before the survey was reported by the majority of radiologists and was significantly influenced by demographic factors. Further investigation is needed to understand the causes of radiologists' discomfort at work and to evaluate interventions to ameliorate these symptoms.
OBJECTIVES: The aim of this study was to compare the diagnostic performance of different sonographic modalities for diagnosing lateral epicondylosis.
METHODS: A total of 50 symptomatic and 50 asymptomatic common extensor tendons in 44 patients with lateral epicondylosis, and 25 healthy participants were prospectively examined by B-mode sonography, color Doppler imaging, power Doppler imaging, Superb Microvascular Imaging (SMI; Toshiba Medical Systems Corporation, Tokyo, Japan), and strain elastography. We evaluated blood flow in common extensor tendons by using a grading system with color Doppler imaging, power Doppler imaging, and SMI. The diagnostic performance of the modalities was compared.
RESULTS: When a cutoff value of hypoechogenicity was used for the mean strain ratio, the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy rates were 92.0%, 94%.0, 93.9%, 92.2%, and 93.0%, respectively. When a cutoff point of grade 1 was used, the sensitivity, specificity, PPV, NPV, and accuracy rates were 26.0%, 10.0%, 10.0%, 57.5%, and 63.0, for color Doppler imaging; 40.0%, 10.0%, 10.0%, 62.5%, and 70.0% for power Doppler imaging; and 84.0%, 94.0%, 93.0%, 85.5%, and 89.0% for SMI. When a cutoff value of 3.94 was used for the mean strain ratio, the sensitivity, specificity, PPV, NPV, and accuracy rates were 78.0%, 92.0%, 90.7%, 80.7%, and 85.0%, respectively. A statistically significant correlation was detected between SMI, strain elastography, and visual analog scale scores (P < .001).
CONCLUSIONS: The combination of SMI and B-mode sonography was found to have excellent diagnostic performance for lateral epicondylosis. Neovascularzation in patients' tendons with lateral epicondylosis was identified much better with SMI compared to color or power Doppler imaging.
Images obtained with the two sequences were interpreted by two musculoskeletal radiologists independently, and the results were analyzed with the surgical diagnosis as the reference AbstractText: Among the 56 patients with suspected ACL injury, the arthroscopic records revealed 14 cases (25%) of complete tear, four cases (7%) of selective posterolateral ...
