Study summary

Investigators are doing this study to determine which of four imaging techniques: Fludeoxyglucose Positron Emission Tomography (18 FDG PET) computerized tomography (CT), 18 FDG PET Magnetic resonance imaging (MRI), C-11 acetate PET CT, and C-11 acetate PET MRI) is the best test for finding sites of active myeloma disease.

Read the detailed description

Participants who are clinically scheduled to undergo F-18 FDG PET/CT myeloma evaluation will also undergo F-18 FDG PET/MRI, and C-11 acetate PET CT/MRI. On Day 1 of study, participants will undergo F-18 FDG PET/CT-MRI. F-18 FDG radiopharmaceutical is infused intravenously, followed by a 60 minute waiting uptake phase. After 60 minutes, participant will undergo PET/CT imaging for 30 minutes. At 90 minutes, participant will undergo PET/MRI imaging for 30 minutes. On Day 2 of study, participants will undergo C-11 PET/CT-MRI. C-11 radiopharmaceutical is infused intravenously, followed by a 10 minute uptake phase. After 10 minutes, participant will undergo PET/CT imaging for 30 minutes, followed by a 60 minute pause with the participant at rest. At the end of 60 minute pause, the participant is given the second C-11 acetate infusion, followed by a 10 minute waiting uptake phase. After 10 minutes, participant will undergo PET/MRI imaging for 30 minutes. On Day 3, study team member makes a phone call to participant for follow up.

Study arms

  • Experimental
    Multiple Myeloma Patients

    Participants will receive 4 different techniques of diagnosis: Fludeoxyglucose (F-18 FDG) PET/MRI, Sodium Acetate (C-11 acetate) PET/CT, C-11 PET/MRI, and F-18 FDG PET/CT. Each participant will receive both PET drugs by both diagnostic techniques and is therefore included in the analysis population for the four reporting groups.

What researchers measure

Primary outcomes

  1. Mean Multiple Myeloma Lesions Detected

    The number of lesions detected in the scans will be averaged for each technique. Two techniques (scans) will be tested on Day 1 and two techniques (scans) will be tested on Day 2.

    Time frame: Day 1, Day 2

Secondary outcomes

  1. Visual Image Analysis of Detected Multiple Myeloma Lesions

    The visual image analysis scale has a range of 0-4: (0 no uptake; 1 benign, 2 probably benign, 3 probably malignant, 4 malignant).

    Time frame: Approximately one month after Day 2
