Does magnetic resonance imaging give value-added than bone scintigraphy in the detection of vertebral metastasis?

Abstract

The authors conclude that the MR imaging is more efficient than the bone scintigraphy in detecting vertebral metastasis, especially in the cases that bone scintigraphy are equivocal or negative for vertebral metastasis in high clinical suspicion. Furthermore, MR imaging is important for the further treatment planning such as radiation therapy or systemic chemotherapy. Although MR imaging is useful in the detection of early metastasis that are localized completely in the bone marrow cavity routinely bone scintigraphy remains that most cost-effective method for examination of the entire skeleton.
