Technical Development of Cardiovascular Magnetic Resonance Imaging (CMR) Using a Low Specific Absorption Rate (SAR) Scanner System
NCT03331380 · View on ClinicalTrials.gov ↗
Study Summary
Background: Researchers are testing version of a system known as a magnetic resonance imagining (MRI) scanner that uses strong magnetic fields, radio waves and the like to create images of the organs in the body. It uses lower energy levels than other MRI scanners. This may help scan people with metal devices in their body, or in invasive heart procedures using metal tools. Objective: To test a new MRI scanner and software changes to create better pictures. Eligibility: People with disease and healthy volunteers, ages 18 and older. Design: Participants will be screened with blood tests. Participants may have both the new MRI and a conventional MRI or only the new one. If 2 are done, they must be within 60 days. For both MRI versions, participants lie on a table that slides into a large tube. During scans, they will hold their breath for up to 20 seconds at a time. Heart activity will be measured by wires connected to pads on the skin. A flexible belt may be used to monitor their breathing. They will be in the scanner up to 2 hours. Participants can agree to have a dye called gadolinium injected into their arm during the scan. This brightens the pictures. Participants can agree to take a drug called a vasodilator. This helps detect areas of the heart with abnormal blood supply. Scans of the heart are taken before, during, and after they get the medicine. The drug may cause temporary chest pain or shortness of breath. They may get other drugs to relieve these symptoms. Sponsoring Institution: National Heart, Lung, and Blood Institute

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT03331380
The ClinicalTrials.gov registry entry for NCT03331380 describes a study currently listed as recruiting. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 2,950 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Heart, Lung, and Blood Institute (NHLBI), which has 381 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with CAD appearing as the primary indexed condition, and to 4 interventions — of which MRI scan - obj 1 is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT03331380 reports 1 study location spanning 1 distinct geographic area — top geographies include Maryland. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
