The Pitfalls of Planar Three-Phase Bone Scintigraphy in Nontraumatic Hip Avascular Osteonecrosis

Abstract

BS is not indicated to diagnose possible contralateral AVN if the hip is asymptomatic. This study emphasizes the results from the literature; if indicated, a radionuclide hip investigation requires the use of a pin-hole collimator, a SPECT study with scatter correction and iterative reconstruction algorithms, or both.
