Abstract:Objective: To investigate the imaging features and diagnostic value of 99mTc-MDP SPECT/CT fusion imaging in painful accessory navicular bone. Methods: 99mTc-SPECT/CT imaging data and clinical data of 32 patients(11 males, 21 females) with confirmed painful accessory navicular bone were retrospectively analyzed. Diagnostic sensitivity, specificity and accuracy of the two different investigations(CT and SPECT/CT imaging) were calculated. Different methods of diagnosis were compared with ?字2 test. Results: Thirty-two patients with 64 feet have 45 case accessory navicular bone, and have the 35 case painful accessory navicular bone. For diagnosis of painful accessory navicular bone, CT has a sensitivity of 40%(14/35), specificity of 81.25%(13/16), positive predictive value of 82.35%(14/17), and negative predictive value of 38.24%(13/34). SPECT/CT has a sensitivity of 100%(35/35), specificity of 81.25%(13/16), positive predictive value of 92.10%(35/38), negative predictive value of 100%(13/13). 99mTc-MDP SPECT/CT has more accurate than CT imaging(P<0.05). Conclusion: 99mTc-MDP SPECT/CT fusion imaging can be used to diagnose painful accessory navicular bone, and has clinical application value.
