To evaluate the prevalence of sarcoid-like reaction to malignancy detected using integrated 2-[(18)F]-fluoro-2-deoxy-d-glucose (FDG) positron-emission tomography and computed tomography (PET/CT) in patients undergoing staging or restaging of solid-organ malignancy. ⋯ Sarcoid-like reaction was suspected in 1.1% of cancer patients at FDG PET/CT examination, with confirmation of the diagnosis in 0.6%. With the increasing use of FDG PET/CT in cancer patients, it is important to be aware of the prevalence of this uncommon, but important, disease entity and to consider this diagnosis in appropriate cases in order to avoid a false-positive interpretation of metastatic disease.

To determine the incidence of nephrogenic systemic fibrosis (NSF) in stage 3 chronic kidney disease patients following intravenous exposure to gadobenate dimeglumine. ⋯ Based on this limited study, NSF does not appear to occur in patients with stage 3 chronic kidney disease exposed to intravenous gadobenate dimeglumine for MRI at standard dosing of approximately 0.1 mmol/kg.

To evaluate the efficacy of ultrasound as a first-line investigation in patients with a clinical soft-tissue mass. ⋯ Ultrasound is an effective diagnostic triage tool for the evaluation of soft-tissue masses referred from primary care.
