BaselinTc99-MIBI scanning predicts survival in multiple myeloma and helps to differentiate this disease from monoclonal gammopathy of unknown significance.

We performed baselineTc(99)-MIBI scanning in 43 patients with multiple myeloma (MM) and in 31 with monoclonal gammopathy of unknown significance (MGUS) patients. We identified two groups of MM patients whose actuarial survival correlated with low or high MIBI scores. MGUS patients had normal or very low scores.
