Non-contrast MR Imaging for Whole Body Cancer Detection and Characterization

Overview

This study aims to learn how to improve MRIs (Magnetic Resonance Imaging) that do not require the patient to be injected with a contrast dye. Researchers expect to learn how to better find and describe tumors in patients with prostate cancer. Participants have a whole body research MRI scan within 90 days of a standard-of-care imaging procedure. The research study will collect copies of those scans to compare to the research scans as part of the study analysis. Patients who have additional standard-of-care scans within 12 months after their research scan may be asked to have a second non-contrast MRI for research within 90 days of their follow-up standard of care imaging. The whole body MRI scan will be compared to the standard-of-care scan for prostate cancer detection and to assess patient response to standard-of-care treatment.

Participants will undergo a whole body non-contrast MRI study with a whole-body protocol incorporating routine clinical sequences as well as non-contrast research sequences. The patient will also undergo clinically indicated standard-of-care imaging such as PET/CT, CT, Technetium-99m bone scan or MRI with contrast as determined by the patient's oncologist. When the standard-of-care imaging has not yet been performed upon enrollment, the research MRI will ideally be performed on the same day as the standard-of-care exam. However, scheduling constraints and patient time constraints may preclude scheduling both scans on the same day. In this case, the scans will be performed within a week 90 days of each other. An experienced radiologist will read both scans and results will be provided to the patient's oncologist for clinical follow up. Patients receiving additional standard-of-care imaging within 12 months after the research MRI may be asked to return for an additional whole body MRI scan within 90 days of their standard-of-care scan. The additional research scan will be requested of patients that have evidence of progression during ongoing standard of care treatment and monitoring. The additional scan would be requested of those patients to compare baseline scans to those that are completed during standard of care imaging. This would be an additional tool to verify disease progression or treatment response.
