Comparison on Imaging Features and Diagnostic Value of Knee Osteoarthritis in Ultrasound and CT Examination

Objective To compare the imaging features and diagnostic value of knee osteoarthritis in ultrasound and CT exa mination.Methods 46 patients with knee osteoa rthritis who were admitted to our hospital from January 2017 to December 2018 were selected.The clinical data and imaging data of 46 patients were collected.All patients underwent ultrasound and CT examinations.And the correct rate of diagnosis was compa red.Results The diagnostic accu racy of CT scan on thinning of a rticular ca rtilage,synovial changes,meniscus changes,soft tissue changes,joint cavity changes,and joint effusion in patients with knee osteoarthritis was 82.60%(19/23),91.30%(21/23),60.80%(14/23),73.91%(17/23),65.21%(15/23),78.26%(18/23),and diagnostic accuracy of ultrasound was 65.21%(15/23),69.56%(16/23),34.78%(8/23),56.52%(13/23),43.47%(10/23),and 60.86%(14/23).The diagnostic accu racy of the CT scan was significantly higher than that of the ultrasound,and the difference was not statistically significant(P>0.05).The diagnostic accu ra cy of CT scan on the echo of a rticula r ca rtilage in patients with knee osteoarthritis was 78.26%(18/23),and the diagnostic accuracy of ultrasound was 47.82%(11/23).The diagnostic accuracy of CT scan was significantly higher than that of ultrasound(P<0.05).Conclusion Ultrasound and CT a re effective in diagnosing knee osteoa rthritis patients,but CT scan is more more beneficial to analyze the location of the lesions of the disease in patients,and has more guiding significance for the formulation of clinical treatment plans.
