UNLABELLED The aim of this study was to evaluate the potential role of positron emission tomography (PET) with 18F-fluorodeoxyglucose (FDG) in patients with unexplained rising serum alpha-fetoprotein (AFP) levels after the treatment of hepatocellular carcinoma (HCC). PATIENTS AND METHODS Thirty-one FDG-PET studies were performed in 26 patients (age range, 45-83; 21 men and 5 women), who had u...

OBJECTIVE The aim of this study is to evaluate the diagnostic performance of FDG-PET/CT for the detection of residual disease after (chemo)radiotherapy in patients with head and neck squamous cell carcinoma (HNSCC) and to evaluate the prognostic value of the FDG-PET/CT findings. METHODS Patients with HNSCC who underwent FDG-PET/CT after (chemo)radiotherapy were studied retrospectively. RESU...

UNLABELLED The aim of this study was to assess the diagnostic performance of (18)F-FDG PET and integrated (18)F-FDG PET/CT for diagnosing recurrent esophageal cancer after initial treatment with curative intent. METHODS The PubMed, Embase, and Cochrane library were systematically searched for all relevant literature using the key words "(18)F-FDG PET" and "esophageal cancer" and synonyms. Stu...

intravascular large b-cell lymphoma (ivlbcl) is a rare and aggressive subtype of systemic extranodal non-hodgkin diffuse large b-cell lymphoma (dlbcl). we report a rare case of ivlbcl who showed diffuse 18f-fluorodeoxyglucose (fdg) uptake in the lung in fdg-positron emission tomography/computed tomography (pet/ct) without respiratory symptoms or chest ct abnormalities. serum biochemical studies...

Objective: To evaluate the clinical impact of (18) F-fluorodeoxyglucose (FDG)-positron-emission tomography/computed tomography (PET/CT) scanning, compared with conventional staging with contrast-enhanced CT imaging (CECT). Patients and methods: The FDG-PET/CT results of 96 consecutive patients with bladder cancer were analysed. Patients included in this study underwent standard CECT imaging of ...

The management of residuals after completion of chemotherapy in advanced seminoma is controversial. It has been proposed that fluorodeoxyglucose-positron emission tomography (FDG-PET) can be used as a follow-up. In this study we investigated FDG-PET as a follow-up tool in advanced seminoma patients treated previously with chemotherapy or radiotherapy. Thirty-seven patients assigned to an advanc...

FDG PET CT scan is considered to be a sensitive tool to detect skeletal metastasis in known malignancies. However, it’s high sensitivity and low specificity may account for false positive diagnosis in cases of trauma, infection, inflammation and other benign conditions. Skeletal hemangioma is one of the common benign conditions which are typically ametabolic on FDG PET CT with no uptake on bone...

Intravascular large B-cell lymphoma (IVLBCL) is a rare and aggressive subtype of systemic extranodal non-Hodgkin diffuse large B-cell lymphoma (DLBCL). We report a rare case of IVLBCL who showed diffuse 18F-fluorodeoxyglucose (FDG) uptake in the lung in FDG-positron emission tomography/computed tomography (PET/CT) without respiratory symptoms or chest CT abnormalities. Serum biochemical studies...

A 58 year old female was referred for FDG-PET/CT for restaging of endometrial adenocarcinoma. For evaluation of treatment, no metastases were detected on FDG-PET/CT which was performed 18 months later after the surgery. During follow-up, FDG-PET/CT was performed 6 months later than the previous FDG-PET/CT for restaging. A lesion with increased metabolic activity (SUV max: 10.21) was detected at...

Positron emission tomography (PET) using [ 18 F]fluorodeoxyglucose (FDG) is a useful modality to examine many kinds of tumors, including primary bone tumors. Malignant bone tumors show higher FDG accumulation than benign tumors and earlier reports mention that FDG-PET can differentiate malignancy from benignancy; however, some benign bone tumors present with high FDG accumulation, which increas...
