INTRODUCTION: To compare the accuracy of graded compression ultrasonography (US) and unenhanced spiral computed tomography (CT) in the diagnosis of @entity697 . METHODS: This prospective study comprised 58 consecutive @entity1 with high clinical suspicion of @entity697 . After careful clinical assessment and laboratory investigations, all the @entity1 were independently evaluated by graded compression US followed by unenhanced spiral CT, in order to establish the diagnosis. CT was performed from the level of the third lumbar vertebral body to the pubic symphysis, and no @entity1 was given oral, rectal or intravenous contrast agents. The results were compared with operative findings and clinical follow-up. RESULTS: Out of the 58 @entity1 evaluated, surgical confirmation was obtained in 52 @entity1 and the remaining six @entity1 were managed conservatively. Statistical analysis was based on the 52 @entity1 who were surgically confirmed. 48 of the operated @entity1 had evidence of @entity698 and four @entity1 had negative findings. In our study, 90 percent of @entity1 were adults and the following results were more applicable to the adult age group. Analysis of the data for US and CT, respectively, revealed a sensitivity of 67.3 percent versus 95.8 percent, specificity of 100 percent versus 75 percent, accuracy of 71.2 percent versus 90.3 percent, positive predictive value of 100 percent versus 97.8 percent, and negative predictive value of 15.8 percent versus 60 percent. Out of the operated @entity1 , four @entity1 did not have @entity697 and alternative diagnosis was suggested by US and CT in one @entity1 . Of the six @entity1 managed conservatively, an alternative diagnosis was reached both by US and CT in two @entity1 . CONCLUSION: We conclude that unenhanced spiral CT is more sensitive than US in detecting @entity698 , especially in adult @entity1 .
