Patients (20-50\u2009years age) with clinical suspicion of proximal hamstring injury were included, after subjecting them to the selection criteria. Ultrasonography was performed using the 9-12 and 12-18 MHZ linear transducers on Siemens S-3000 machine, while MR imaging was done on 3 Tesla GE Discovery machine.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Fifty patients (M:F\u2009=\u200933:17) were included in the study. Ultrasonography detected proximal hamstring injuries in 34 (68%) participants, consistent with magnetic resonance imaging (MRI) findings. Tendinopathy emerged as the most prevalent diagnosis (42%), followed by isolated tears (14%) and combined tendinopathy and tears (12%). USG demonstrated a sensitivity of 91.2% and a specificity of 81.2%, with an overall diagnostic accuracy of 88%. The positive predictive value and negative predictive value were 91.2% and 81.2%, respectively. A Cohen\u2019s Kappa coefficient of 0.724 indicated substantial agreement between USG and MRI findings.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Ultrasonography is a reliable and cost-effective diagnostic tool for proximal hamstring injuries, demonstrating high concordance with MRI.
