Öğe Chronic myeloid leukemia detected on FDG PET/CT imaging in a patient with renal cell carcinoma(Elsevier Doyma Sl, 2013) Varoglu, E.; Kaya, B.; Sari, O.It is well known that hematopoietic cytokine stimulation can cause increased fluorodeoxyglucose (FDG) accumulation in bone marrow on PET/CT imaging, which simulates that seen in patients with bone marrow metastases. However, increased bone marrow FOG uptake can be caused by other etiologies. We report a patient with operated renal cell carcinoma had no history of hematopoietic cytokine stimulation. The FDG PET/CT images showed increased bone marrow FDG uptake, and the patient was diagnosed as chronic myeloid leukemia. This case revealed that increased FDG uptake on bone marrow may be related to neoplastic disease of the hematopoietic tissues. (C) 2012 Elsevier Espana, S.L. and SEMNIM.

Some researchers found that hepatosteatosis significantly changed the hepatic (18)FDG uptake, while others did not. This study investigated whether the liver's (18)FDG uptake was affected by the diffuse fatty infiltration of the liver. Material and methods: A total of 156 cases were included in this study. Different patient groups were defined according to the liver Hounsfield unit (HU). The HU was calculated from an unenhanced CT, for all patients, and we calculated the mean standardized uptake value (STmean) and maximum standardized uptake value (SUNmax) on an (18)FDG PET scan. For this purpose, we placed regions of interest (ROIs) on the liver image. We statistically compared the SUVmean and SUVmax measured in the fatty liver patients and the control group. Results: The average SUVmean and SUVmax values were calculated as 2.58 +/- 0.66 and 3.94 +/- 1, respectively, in the patient group and 2.54 +/- 0.57 and 3.7 +/- 0.88, respectively, in the control group. We found the average SUVmean and SUVmax values in the fatty liver group and its subsets were not significantly different from the values in the control group (p > 0.05). We also did not find any statistically significant correlation between average liver density (HU) and the average SUV values (p > 0.05). Conclusion: Fatty infiltration may not have a significant effect on the liver's (18)FDG uptake. Thus, the liver may be used as a reference or comparator on (18)FDG PET scans in patients with fatty liver disease. (C) 2012 Elsevier Espana, S.L. and SEMNIM.
