The use of intravenous sedation and analgesia in patients undergoing interventional diagnostic and therapeutic procedures is increasing. Sedation by non-anaesthetists is considered to be safe, provided that they have received adequate training and have the necessary equipment, facilities, and personnel. This article aims to increase awareness of the safe use of sedative drugs in radiology and provide a practical guideline for minimal and moderate sedation.

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.
