A 14-year-old girl was examined for a right lateral neck swelling and radiographic mediastinal widening. Biopsy of a right supraclavicular lymph node demonstrated the nodular sclerosing form of Hodgkin's lymphoma. An 18F-fluorodeoxyglucose-positron emission tomography/computed tomography (F18-FDG-PET/CT) study showed several pathological areas of lymph-node uptake in the upper mediastum and rig...

As a nuclear approach, Positron Emission Tomography (PET) is a functional imaging technique which is based on the detection of gamma ray pairs emitted by a positron-emitting radionuclide. There are certain limitations to this technique such as normal tissue uptake. Therefore, it has been recommended that patients prepare before scanning. Fasting for a short while before PET imaging is an exampl...

Mesothelioma is a neoplasm originating from the serous membranes, most often pleura. We present 72-year-old man with hypoxemic respiratory failure associated unilateral pleural effusion. The computed tomography (CT) of chest didn’t show other alterations besides Thoracoscopy showed thickening described as reactive mesothelial hyperplasia. Repeated contrast- enhanced CT mass in posterior mediast...

We report a case of Hodgkin lymphoma (classic type) referred for response assessment after two cycles of chemotherapy with ABVD regiment. The F-18 fluorodeoxyglucose positron emission tomography (F-18 FDG PET/CT) showed hypermetabolic cutaneous and subcutaneous lesions with a linear pattern in the left arm with significant F-18 fluorodeoxyglucose positron accumulation in associate with left axi...

UNLABELLED In this theoretic note, the rationale for the physical decay correction of the (18)F-FDG input function in dynamic PET is investigated, using the Patlak equation as an example. METHODS The Patlak equation conventionally obtained when correcting the (18)F-FDG input function and correcting the tissue activity measurement for (18)F physical decay can also be derived from a 2-compartme...
