Bone marrow edema (BME) is a condition detectable with magnetic resonance imaging (MRI) and is present in different stages of osteoarthritis (OA). Its pathogenesis is still not completely known. ⋯ BME is not a static phenomenon but changes over time. Correlation to physical activity and local inflammatory reaction should be evaluated.

Accurate staging is necessary to determine the appropriate therapy in patients with lung cancer. Few studies have compared integrated fluorine-18 fluorodeoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) and contrast-enhanced CT in the characterization and staging of pulmonary tumors considered eligible for surgical resection. ⋯ In patients with lung neoplasms considered eligible for surgical resection, (18)F-FDG PET/CT versus contrast-enhanced CT revealed higher sensitivity in nodal staging, but lower specificity both in lesion characterization and nodal staging.

Early detection of hypoxic-ischemic (HI) injury in the asphyxic newborn is important because present prognostic factors are inadequate. Furthermore, therapeutic interventions may have additional benefit if initiated in time. ⋯ Diffusion MRI and proton MRS can detect HI injury in the piglet brain 7 hours after hypoxia. DWI and MRS can be used to give useful prognostic information. This piglet model may potentially be used to mimic clinical situations and is suitable for further research investigating HI injury.
