Increasing Role of FDG-PET/CT in Detecting Bone Marrow Metastasis of Solid Tumors in Adults: An Analysis of Ten Patients

Figures

Figure 1. Axial PET/CT and MIP (maximum intensity projection) FDG PET/CT images revealed heterogeneously widespread increased FDG uptake at the skeleton which suggests bone marrow involvement.

Figure 2. Axial and MIP PET/CT showed a mass with intense FDG uptake at the sigmoid colon consistent with primary tumor. Also, there was heterogeneously increased FDG accumulation at the skeleton suggestive for bone marrow metastases.

Figure 3. Axial and MIP PET/CT images showed primary tumor with intense FDG accumulation in rectosigmoid. There were also multipl bone-bone marrow metastases and extraskeletal metastases with prominent FDG uptake.

Figure 4. Axial and sagittal PET/CT images depicted multiple heterogeneously increased FDG uptake at vertebral column.

Figure 5. Axial and MIP PET/CT images showed a mass at the right hilar region with very intense FDG accumulation. There were also multipl bone-bone marrow metastases and extraskeletal metastases with prominent FDG uptake.
