Chemical-Shift-Encoded MRI for Active Bone Marrow Dosimetry in Radiopharmaceutical Therapy

Краткое описание

This study compares two different imaging procedures to each other, one using positron emission tomography (PET) with fluorothymidine F-18 (FLT) (FLT PET for short), and the other using chemical shift-encoded (CSE) magnetic resonance imaging (MRI) or CSE-MRI for short, to determine specifically if CSE-MRI is as accurate as FLT PET in telling the difference between active and inactive marrow. The best way to do the comparison between the two imaging procedures is if they are done at the same time on the same patient. This is possible with use of a scanner at the University of Wisconsin Hospitals and Clinics (UW Health), the GE SIGNA PET/MR scanner. The prediction is that CSE-MRI as accurate as FLT at telling the difference between active and inactive marrow in patients with metastatic prostate cancer, and that is the primary reason for this study. 15 participants will be enrolled and on study for up to 14 months.
