FDG PET/CT in pediatric Hodgkin's lymphoma

The increased glucose metabolism results increased 18F-Fluorodeoxyglucose (FDG) accumulation of the malignant cells. Similarly, Hodgkin's lymphoma (HL) show high FDG uptake. Lymphocyte-predominant types of HL demonstrate lower FDG accumulation than classic type HL. PET/CT can detect almost all lesion greater than 0.5-1 cm. Additionally, FDG PET/CT help us in monitoring treatment response by showing glucose metabolism and FDG uptake of the cells after chemotherapy. The sensitivity of FDG PET/CT is higher than other imaging modalities in detecting nodular or diffuse lesions of HL. Also, it has higher sensitivity in showing bone marrow involvement than bone marrow biopsy. As a result, FDG PET/CT is a widely accepted and superior imaging modality in staging, re-staging and evaluating treatment response of pediatric HL

Laryngeal squamous cell cancer with late presentation of isolated liver metastasis on fluorodeoxyglucose positron emission tomography-computed tomography

Laryngeal cancer is the second most common type of head and neck malignancy, representing approximately 45% of all head and neck cancers. Hematogenous spread to the liver rarely occurs without evidence of pulmonary and bone disease. We report a patient who had been treated 7 years earlier for laryngeal squamous cell cancer and who had isolated liver metastasis on fluorodeoxy D-glucose positron emission tomography-computed tomography

Breast Uptake of Ga-68 DOTA-TATE in a Nursing Woman with Net Diagnosis

Neuroendocrine tumors are heterogenous group of tumors that expresses somatostatin receptors on their cell surfaces. PET/CT with Ga-68 labeled somatostatin analogues has been used as an important imaging modality in the NETs. It's important to know normal biodistribution of radiotracer to avoid misinterpretation. We report physiologic breast uptake of Ga-68 in a nursing patient

The role of FDG-PET/CT in detecting unsuspected and unknown distant metastasis in the initial staging of NSCLC

Background/aim: Our purpose in this retrospective study was to determine the ratio of unexpected [metastases within the coverage area of thorax computed tomography (CT)] and unknown (metastases out of the coverage area of thorax CT) metastases by positron emission tomography/CT (PET/CT) in patients with newly diagnosed non-small cell lung cancer (NSCLC) who had no defined metastatic lesion, and to investigate the contribution of fludeoxyglucose (FDG)-PET/CT in metastasis staging

FDG and FDG-labelled leucocyte PET/CT in the imaging of prosthetic joint infection

Purpose The demand for arthroplasty is rapidly growing as a result of the ageing of the population. Although complications such as heterotrophic ossification, fracture and dislocation are relatively rare, differentiating aseptic loosening, the most common complication of arthroplasty from infection, is a major challenge for clinicians. Radionuclide imaging is currently the imaging modality of choice since it is not affected by orthopaedic hardware. Whereas FDG PET/CT imaging has been widely used in periprosthetic infection, it cannot discriminate aseptic from septic inflammation. In this study we aimed to evaluate the role of FDG PET/CT and FDG-labelled leucocyte PET/CT in the diagnosis of periprosthetic infection

The role of FDG PET/CT in detection of distant metastasis in the initial staging of breast cancer

Background/aim: We aimed to evaluate the role of FDG PET/CT in the detection of extraaxillary regional nodal/distant metastasis in breast cancer patients and to assess the value of FDG PET/CT for detecting distant metastases in patient subgroups
