Elastography is an imaging method that can report the strain and elastic modulus of the biological tissue. We think acoustic radiation force impulse (ARFI) elastography can effectively assess rotator cuff tendinopathy. Purpose This study aimed to investigate the usefulness of ARFI elastography in evaluating supraspinatus tendinopathy. Materials and Methods We included 44 patients (22 men, 22 women, median age, 47 years; range, 20-69 years) with unilateral supraspinatus tendinopathy diagnosed with magnetic resonance imaging (MRI) in this prospective study. The normal tendons and tendinopathies, including supraspinatus tendinosis, partial-thickness, and full-thickness supraspinatus tears, were evaluated with ultrasound and ARFI elastography. The ARFI elastography values were compared between healthy and tendinopathy groups, and the gender was compared between elastography values of the normal tendons and tendinopathies using the Mann-Whitney U test. Results The values of ARFI elastography correlated with tendinopathy. (P = 0.001). The gender differed between the elastography values of the normal tendons (P = 0.002) and tendinopathies (P = 0.001). Conclusion ARFI elastography is a non-invasive and feasible method for quantitatively assessing supraspinatus tendinopathy. It can be an alternative method to MRI in diagnosing supraspinatus tendinopathy.eninfo:eu-repo/semantics/closedAccessARFI elastographyquantitative assessmentrotator cuffshear wave elastographysupraspinatus tendonshoulder painArticle10.2174/15734056196662211151358422-s2.0-85158932176635636380445Q363119WOS:001008458100010N/A
