Abstract Objective The purpose of this study was to evaluate the application of sonography at the polyclinic of the Olympic/Paralympic village during the Olympic/Paralympic Games. Methods We retrospectively reviewed 759 consecutive patients who underwent sonography at the ultrasound division of the polyclinic in the Olympic/Paralympic village from July 20, 2008, to September 20, 2008. Prevalence of emergency sonography after sports injury and non-sports-related urgent conditions during the games was analyzed. The benefit of sonographic services in large sporting events was discussed. Results There were 759 patients (484 athletes, 101 coaches, 88 team officials, and 86 volunteers; 462 men and 297 women) in the ultrasound division at the polyclinic. The indications for sonography included abdominal pain (315 cases, 41.50%), muskuloskeletal disorders (228 cases, 30.04%), gynecology related (104 cases, 13.70%), cardiac conditions (49 cases, 6.46%), small parts (29 cases, 3.82%), and vascular problems (34 cases, 4.48%). The rates of positive findings on sonography were 46.03% in the abdomen, 70.17% in musculoskeleton, 41.34% in gynecology, 10.20% in the heart, 75.86% in small parts, and 38.24% in vessels, respectively. Conclusion Sonography plays an important role in the medical services at the polyclinic in the Olympic/Paralympic village. The benefits of sonography in such large sporting events are accuracy, fast result, portability, and noninvasiveness.
