FIGURE 2. Coronal 18F-FDG PET image (A) and 18F-FLT PET image (B) of patient 9, with multiple lesions in both lungs on 18F-FDG PET and no lesions on 18F-FLT PET. Metastasis in the right acetabulum, which had been irradiated 1 wk earlier, is prominent on 18F-FDG PET (large arrow) but less intense on 18F-FLT PET (large arrow). In addition, irradiated bone marrow cranial of tumor has become metabolically inactive, as is seen on 18F-FLT as uptake less intense than that in nonirradiated bone marrow (small arrow).
