    Effect of R-CHOP chemotherapy on liver and mediastinal blood pool 18F-FDG standardized uptake values in patients with non-Hodgkin's lymphoma
    (Elsevier Science Inc, 2015) Kaya, Bugra; Dostbil, Zeki; Ismailoglu, Murat; Tasdemir, Bekir; Sahin, Ozlem
    Aim: We aimed to investigate the impact of chemotherapy on F-18-FDG uptake in the liver and mediastinal blood pool (MBP) among patients with non-Hodgkin's lymphoma. Methods: Twenty-three patients with NHL underwent baseline, interim, and postchemotherapy F-18-FDG PET/CT. SUVmax and SUVmean values of the liver and MBP at imaging time were compared statistically. Results: We did not find any significant differences between the liver and mediastinum SUVmean and SUVmax values (P>.05). Conclusions: Our study demonstrates that the F-18-FOG uptake in the liver and MBP are not significantly affected by R-CHOP chemotherapy in patients with NHL. (C) 2015 Elsevier Inc.

    F-18 fdg pet/ct imaging in a patient presenting with mediastinal lymphadenopathies: a case of sarcoidosis
    (Drunpp-Sarajevo, 2012) Dostbil, Zeki; Kaya, Bugra; Sari, Oktay; Varoglu, Erhan
    F-18 FDG PET/CT has been used increasingly in evaluation of pulmonary and mediastinal lesions. However, inflammatory and granulomatous disorders may show increased F-18 FDG uptake on PET scanning. So, some benign conditions may cause false-positive results in cancer investigation. In this case, F-18 FDG PET/CT findings were presented in a patient with sarcoidosis who was investigated for primarily suspected malignancy.
