Fluorodeoxyglucose positron emission tomography with computed tomography detects greater metabolic changes that are not represented by plain radiography for patients with osteonecrosis of the jaw.

Purpose: Imaging is important to identify subclinical changes and for treatment planning in patients with osteonecrosis of the jaw (ONJ) exposed to antiresorptive therapy. The aim of this study was to compare the findings at radiography with those at fluorodeoxyglucose (FDG) positron emission tomography (PET) with computed tomography (CT) for patients with ONJ related to antiresorptive therapy.

Materials And Methods: A cross-sectional retrospective analysis of patients with clinically identified ONJ lesions of the mandible was performed.

Initial experience with FDG-PET/CT in the evaluation of breast cancer.

Purpose: We retrospectively reviewed FDG-PET/CT images in patients with breast cancer to determine whether PET/CT improved the level of diagnostic confidence as compared with PET and to compare PET/CT and CT findings at the location of suspected malignancies.

Methods: The study included 75 patients with known breast cancer. The initial PET/CT study for each patient was retrospectively reviewed to determine whether improved diagnostic confidence (IDC) regarding lesion localization and characterization was observed with PET/CT as compared with PET alone.

"USA-Fat": prevalence is related to ambient outdoor temperature-evaluation with 18F-FDG PET/CT.

Unlabelled: Increased (18)F-FDG activity in fatty tissue has previously been reported with PET/CT. We previously named this activity uptake in supraclavicular area fat ("USA-Fat"). We and others have speculated that this uptake exists in metabolically active brown adipose tissue (BAT).
