The value of 99mTc-MDP bone SPECT/CT in evaluation of patients with painful knee prosthesis

Abstract

Tc-MDP SPECT/CT has better sensitivity and specificity compared with Tc-MDP TPBS in diagnosis of aseptic loosening and periprosthestic infection in patients with painful knee arthroplasty. Tc-MDP SPECT/CT identified alternative causes of pain in 43% of patients, which was not identified by Tc-MDP TPBS.
