Calibration of MR and PET-MR Imaging Protocols at RIC

August 19, 2024 updated by: Daniel S. Berman, Cedars-Sinai Medical Center

Calibration of MR and PET-MR Imaging Protocols at the Cedars-Sinai Medical Center (CSMC) Biomedical Imaging Research Institute (BIRI) Research Imaging Core

This is a protocol to facilitate on-site calibration of the technical aspects of the Siemens Biograph mMR (molecular MR) Positron Emission Tomography-Magnetic Resonance (PET-MR) scanner and the 3T Siemens Vida MR scanner at the Cedars-Sinai Medical Center (CSMC) Biomedical Imaging Research Institute (BIRI) Research Imaging Core after scanner installation. The mMR is a FDA-approved standard clinical device (non-experimental) and will be used in accordance with clearance and approval from the FDA. The Vida is a state-of-the-art FDA approved scanner and will be clinically licensed within a short time.

Detailed Description

PET-MR Protocol on the Biograph mMR: This protocol requires the use of a radioisotope. To avoid administering radioisotope solely for the purposes of this calibration, we will recruit 20 patients from the clinical population at the S. Mark Taper Foundation Imaging Center at CSMC who are already receiving an isotope dose for their standard-of-care examination and are willing to be scanned at the Research Imaging Core on the same day right after their clinical exam. Subjects who are having a PET-MR after receiving FDG will have the same body part scanned as they did for clinical testing.

MR-only Protocol on the Biograph mMR:To set up MR-only protocols, we will enroll 20 volunteers for MR-only on the mMR scanner. This is a standard MR scan with no isotope involved. Those volunteers who are participating in the MR-only scan will have major body parts and organs scanned as needed for calibration.

MR imaging on the Siemens Vida 3T scanner: applications training is taking place and we will build clinical protocols in the future

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Other: PET-MR imaging on Biograph mMR scanner
Research PET-MR imaging on Biograph mMR scanner will be conducted immediately following administration of FDG for clinically approved scan. No additional radioisotope will be administered for the research scan.
Other: PET-MR imaging on Biograph mMR scanner
Participants will undergo PET-MR imaging on the Biograph mMR scanner to evaluate the technical aspects of the total acquisition protocol directly post clinical administration of FDG, thus removing the requirement for additional radioisotope.
Other Names:
  • PET-MR
  • Siemens Biograph mMR
  • molecular imaging
  • mMR
Other: MR-only imaging on Biograph mMR scanner
Participants will undergo research MR-only imaging on Biograph mMR scanner.
Other: MR-only imaging on Biograph mMR scanner
Participants will undergo MR-only imaging to test the technical aspects of the MR-only protocol on the Biograph mMR scanner. No drug administered.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
composite of measures of organ uptake, maximum target-to-background ratio and maximum standard uptake value as standard with FDG PET for maximum image quality for all standard protocols.
Time Frame: one day
The mMR is a FDA-approved standard clinical device (non-experimental) and will be used in accordance with clearance and approval from the FDA. Results obtained from these tests will not be analyzed towards the end point of any study and will solely be used to finalize and calibrate the technical performance of the new scanner. All scans will be visually assessed for technique calibration.
