Abstract：Objective To explore the imaging features and diagnostic value of osteoid osteomas ( OOs) in multislice CT ( MSCT) examination. Methods Clinical and imaging data of 87 OOs patients confirmed by pathology was retrospectively analyzed, and the patients were divided into MSCT group (n=33) and X-ray group (n=54) according to different examina-tion methods, and then the advantages and disadvantages of MSCT and ordinary X-ray photography in diagnosis value were compared. Results There were 57 males and 30 females of 5 -38 years old (average 19 ±5. 7). Micro-lesions OOs (diameter<5 mm) were found in 15 cases (45. 5%) in MSCT group and 3 cases (5. 6%) in X-ray group;sclerotin calcifi-cation was found in 33 cases (100%) in MSCT group and 49 cases (90. 7%) in X-ray group, and the differences in the two groups were statistically significant (P<0. 05). Cortical bone OOs and articular OOs were detected at 54. 5% and 6. 1% in MSCT group and 20. 4% and 29. 6% in X-ray group respectively, and the differences in the two groups were statistically sig-nificant (P<0.05). Conclusion MSCT in diagnosis of micro-OOs and sclerotin calcification lesions is more sensitive and accurate, while X-ray plain film is more sensitive in diagnosis of articular OOs.
