Figure 3.

Results of X-ray, low-dose CT and PET. The individual results of the different imaging methods performed at baseline for the 35 previously untreated multiple myeloma patients. Below the columns are the numbers of positive, negative and missing results of each imaging modality shown. Low-dose CT identifies most patients with osteolysis. Black squares illustrate osteolysis at low-dose CT (CT), conventional X-rays (X-ray), and focal activity at ¹⁸FDG-PET (PET), while white squares illustrate imaging without osteolysis of focal activity. Grey squares represent missing data.
