The Added Value of Bloodpool SPECT/CT in Painful Non-Operated Foot and Ankle Undiagnosed With Standard Three-Phase Bone Scintigraphy
Purpose: To evaluate the interest of adding a bloodpool SPECT/CT to standard three-phase bone scintigraphy (BS) for etiological diagnosis of subacute and chronic lower extremity pains.Methods: We prospectively included patients addressed for pain of lower extremities lasting for at least 6 weeks, wi...

Inter-reader agreement was not significantly impacted.Conclusion: Adding bloodpool SPECT/CT to standard three-phase BS impacted diagnostic conclusion in a quarter of the patients with painful lower extremities, notably by revealing significantly more tendonitis.https://www.frontiersin.org/articles/10.3389/fmed.2021.634419/fullbloodpool SPECTbone scintigraphyanklefootearly SPECT/CT |
