WebFeb 28, 2024 · Our data confirms that SPECT/CT arthrography has a high diagnostic accuracy for detecting aseptic loosening in patients with persistent pain following primary hip and knee arthroplasties (sensitivity of 86%, specificity of 98%, PPV of 86%, NPV of 98%, and overall accuracy of 97%). WebThe SPECT tracer emits gamma radiation directly, as opposed to PET where the gamma radiation is emitted indirectly. Because SPECT does not use coincidence detection there is decreased resolution. SPECT is much less expensive than PET and uses longer lived and more variable radiolabeled tracers.
