Evaluation of Attenuation Correction Accuracy in Positron Emission Tomography-Magnetic Resonance Imaging (PET-MRI)
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
The purpose of this research proposal is to establish a mechanism to develop tools that will allow the investigators to measure the impact of magnetic resonance (MR) acquisition correction sequences for attenuation correction on positron emission tomography (PET) quantitation accuracy.

Layout table for eligibility information
Ages Eligible for Study:
18 Years and older (Adult, Older Adult)
Sexes Eligible for Study:
Accepts Healthy Volunteers:
Patients seen at Washington University School of Medicine
Participant must be ≥ 18 years of age
Participant can be a male or a non-pregnant female.
Successful completion of MRI screening form
Participant must have undergone a PET/CT examination with injection of a standard dose of 18F-fluorodeoxyglucose (FDG) or other PET tracer with a half-life greater than one hour either for clinical or research purposes within 3 hrs of the proposed PET-MRI examination.
Participant will be fully informed and has personally signed and dated the written Informed Consent and Health Insurance Portability and Accountability Act (HIPAA) provisions
Subjects for whom exposure to a strong magnetic field would be a health risk (e.g., subjects with cardiac pacemakers or non-MR compatible metallic implants)
Women who are pregnant.
Subjects who require sedation to participate will be excluded.
Patient/participant has a medical condition which in the judgment of the investigator might make supine positioning for the duration of the scan unsafe, such as (but not limited to) congestive heart failure or significant pulmonary disease.
