Abstract：Objective To investigate ultrasound and CT findings of parathyroid adenoma ( PTA) , comparing the di-agnostic value of the two methods .Methods Ultrasound and CT findings were retrospectively analyzed in 40 patients with pathologically confirmed PTA .Sensitivity of the method used to compare the two kinds of diagnostic accuracy .Results 39 ca-ses of preoperative ultrasound examination , 30 patients were diagnosed as PTA , sonographic features mostly solid hypoechoic , often originated in the lower parathyroid glands , 19 cases of PTA rich blood flow signals , the longest diameter >3 cm or cystic nodules 1-2 cm blood sparse;CT features PTA mostly unenhanced low density or soft tissue density , enhanced showed moder-ate enhancement , cystic degeneration occurs mostly heterogeneous enhancement and visible punctate calcification .High-fre-quency ultrasound diagnostic with sensitivity of 76.9%, accuracy of 76.7%; spiral CT diagnostic sensitivity of 78.8%, 71.8%of accuracy,sensitivity and accuracy differences between the two kinds of imaging methods showed no significance (P >0.05).Two kinds of imaging methods consistency is good (Kappa value=0.52).Conclusion Ultrasound and spiral CT ex-amination in favor of the combination of early screening parathyroid tumor , and make a judgment on its location and cystic .
