Context: High-frequency ultrasound (US) of painful rheumatoid joints allows an increasingly refined analysis of the extent of joint involvement and disease activity. Aims: The aim of this study was to establish the role of the US in the evaluation of painful hand joints in patients with rheumatoid arthritis (RA) and its comparison with Conventional Radiography (CR) changes. Settings and Design: Cross-sectional study. Subjects and Methods: Patients diagnosed with RA were assessed by a thorough clinical examination and relevant laboratory investigations. After X-ray imaging, grayscale, and power Doppler US examination of the wrist, metacarpophalangeal, and proximal interphalangeal joints of both hands were performed using a high-frequency linear transducer. Statistical Analysis Used: SPSS version 20.0 (a statistical package for the social sciences) was used to collect, tabulate, and analyze all data. The results were presented as mean standard deviation or percentage. Differences in categorical data were compared using the Chi-square test and Fisher's exact test. A P < 0.05 was considered statistically significant. Results: Thirty-two of the 51 individuals studied had radiographic abnormalities, whereas 44 had abnormal findings in the US. The US can detect erosions in 37 patients, including all 15 of those who had radiographically visible erosions. A statistically significant difference was noted between the findings of radiography compared with US findings (P < 0.001). Conclusions: US is more sensitive than CR for the detection of erosion and can complement the CR in the evaluation of these patients.
