{"eventGroups":[{"deathsNumAffected":0,"deathsNumAtRisk":31,"description":"Participants will have three imaging studies on separate days: a standard positron emission tomography/computed tomography scan (18-FDG PET/CT), a PET/CT scan with an experimental sodium fluoride-based drug (18-NaF PET/CT), and magnetic resonance imaging (DCE-MRI).\n\n18-NaF PET: The patient will patient will receive 5mCi of F-18 NaF IV bolus, followed by a \\~20 ml saline (sodium chloride IV infusion 0.9% w/v) flush over a period of \\~20 seconds. Serial dynamic imaging (2 minutes/bed position) will be obtained over a 1-hour period. The patient will be permitted an imaging break until a static PET/CT is performed beginning at 2-hours post F-18 NaF injection. DCE-MRI: An FDA approved gadolinium chelate (e.g. Magnevist, Berlex Laboratories, NJ, USA) will be administered intravenously at 3 cc/sec using an automated pump injector (Medrad, Pittsburgh, PA, USA).18-FDG PET/CT: The 18F-FDG injection procedure will be injected and be followed by a \\~20 ml saline flush over a period of \\~20 sec.","id":"EG000","otherNumAffected":0,"otherNumAtRisk":31,"seriousNumAffected":0,"seriousNumAtRisk":31,"title":"Imaging in MGUS, SMM, and MM"}],"frequencyThreshold":"0"}
