Giant Polyostotic Fibrous Dysplasia: F-18-flourodeoxyglucose Positron Emission Tomography/Computerized Tomography and Radiologic Findings

Image Findings of Polyostotic Fibrous Dysplasia Mimicking Metastasis in F-18 FDG Positron Emission Tomography/Computed Tomography

Fibrous dysplasia (FD) of the bone is characterized by the medullary cavity of bones becoming filled with fibrous tissue, and its etiology remains unknown. It is usually asymptomatic and found incidentally on imaging studies that are performed for other purposes. FD may closely mimic the appearance of bony metastatic disease on radiological examinations. We report the case of a 45-year-old fema...

An 18-year-old man was referred to the authors' institution's thoracic cancer specialists for further consultation after abnormal findings were seen on chest radiograph.

(18)F-fluorodeoxyglucose positron emission tomography and MR imaging findings in Rasmussen encephalitis.

BACKGROUND AND PURPOSE Rasmussen encephalitis is a chronic, progressive encephalitis that manifests as an abrupt-onset, intractable seizure disorder in previously developmentally normal children. The objectives of the current study were to characterize the (18)F-fluorodeoxyglucose (FDG) positron emission tomography (PET) and MR imaging findings in Rasmussen encephalitis and to test the hypothes...

Positron emission tomography (PET) imaging with (18)F-based radiotracers.

Positron Emission Tomography (PET) is a nuclear medicine imaging technique that is widely used in early detection and treatment follow up of many diseases, including cancer. This modality requires positron-emitting isotope labeled biomolecules, which are synthesized prior to perform imaging studies. Fluorine-18 is one of the several isotopes of fluorine that is routinely used in radiolabeling o...
