Comparative Study of Conventional 1.5 and 3.0T MR Images With Synthetically Reconstructed MR Images

This study is a prospective, blinded, multi-center multi-reader (MCMR) clinical trial that is statistically powered for non-inferiority of diagnostic image quality of synthetic MR versus conventional MR and collection of supporting radiologic findings and morphology data from radiologists that reflect anticipated clinical usage of synthetic MR technology.

The study consists of three parts:

• Clinical MR acquisition,
• synthetic MR post-processing at a GE facility, and
• blinded image evaluation (BIE) of conventional and synthetic images for each subject.

The study will enroll eligible adult subjects with clinical indications for brain MRI that meet applicable site MR safety criteria and are not pregnant. The study consists of one visit, the subject's MRI scan, without additional follow-up. Results are expected to be representative of expected clinical usage of synthetic MAGiC MR technology in clinical practice.

Inclusion criteria

Subjects must:

• Be an adult 18 years of age or older;
• Have clinical indication for MRI of the brain according to the site standard of care;
• If female of childbearing potential (not surgically sterile or post-menopausal), be determined non-pregnant by a medically qualified investigator or demonstrated non-pregnant by negative urine pregnancy test;
• Be able to hear and understand instructions without assistive devices;
• Have necessary mental capacity to understand instructions be able to comply with protocol requirements;
• Are able and willing to provide written informed consent by signing the informed consent form (ICF).

Exclusion criteria

Subjects will be excluded that:

• Were previously enrolled in this evaluation;
• Have metallic/conductive or electrically/magnetically active implants or attached medical devices (except for dental devices/fillings, surgical clips, and surgical staples) that could be unsafe for MRI;
• Have contraindication(s) to MRI scanning per the routine MR Safety Screening policy of the investigational site;
• Have severe trauma or pre-existing pathology that is expected to interfere with normal conduct of MR scanning or complete scanning of the brain;
• Have medical condition(s) such as those requiring urgent medical care that, in the opinion of a physician Investigator, would prevent safe participation in the study.
