Trial summary

This study will examine ways to establish and standardize normal measurements for children, specific to gender, age, and body surface, when using magnetic resonance imaging (MRI). MRI, which was introduced in the 1980s, is being used more frequently for children. Read more about this study

  • <TAB>
  • To assess whether subjects are indeed normal, the legal guardian will be asked to fill out a questionnaire. Subjects also will be excluded for a paralyzed hemidiaphragm, morbid obesity (BMI greater than 30%), claustrophobia, smokers, significant asthma (greater than one asthma attack per month for the past three months), pregnancy, major medical illness requiring regular medications (such as steroids that may alter muscle mass, sickle cell disease, thalassemia), history of cardiac disease (requiring SBE prophylaxis when visiting the dentist), and/or history of significant previous surgery that may alter cardiac anatomy (such as diaphragmatic hernia, tracheoesophageal fistula).
  • Females of menstruating age will receive a pregnancy test as part of the screening process to participate in this protocol. If they do not wish to be tested, they cannot participate in this voluntary protocol.

About this study

Official title: Cardiovascular Magnetic Resonance Imaging of Pediatric Healthy Volunteers

This study will examine ways to establish and standardize normal measurements for children, specific to gender, age, and body surface, when using magnetic resonance imaging (MRI). MRI, which was introduced in the 1980s, is being used more frequently for children. In this study, researchers seek to understand how a child's heart is different from that of an adult, when an MRI is used for tests. More children with congenital heart disease are living longer. Researchers are looking for a better way to assess their cardiac anatomy and function, and to compare findings with normal function.

Patients ages 8 to 21 in good health and who do not smoke may be eligible for this study. There will be a blood or urine test to check for pregnancy in female volunteers who have begun menstruating or who are over age 12. Pregnancy test results must be negative for those patients to stay in the study. The MRI technique uses a strong magnetic field and radio waves to obtain images of body organs and tissues. For that procedure, patients will lie still on a table that slides into the enclosed tunnel of the scanner. They will be in the scanner from 20 to 60 minutes. As the scanner takes pictures, patients will hear knocking or beeping sounds, and they will wear earplugs to reduce the noise. Patients will be able to communicate with the MRI staff at all times during the scan. At any time, patients or their parents may ask that the patients be moved out of the machine. If they would like, patients can bring a music CD or listen to a radio station through headphones. Some MRI techniques require monitoring while the patient is undergoing the scan. For monitoring of the heart, an electrocardiogram (EKG) will be performed to make sure that the heart rhythm is normal and that heart disease is not present. Patients may be asked to wear adhesive patches that are attached to wires of the EKG machine on their chests. To monitor breathing, patients may be asked to wear a rubber belt that stretches as they take a breath. So that the best quality images are produced, patients may be asked to hold their breath for about 15 seconds.

During the MRI scan, patients may experience peripheral nerve stimulation, usually experienced as a muscle twitch. It is caused by rapid switching of magnetic fields and is not serious. Patients who feel a muscle twitch should report that sensation to the person performing the scan. It is possible, though unlikely, for a painful sensation to result from nerve stimulation. Patients should immediately report if they have pain so that the scan can be stopped.

Read the detailed description

A cardiac MRI (Magnetic Resonance Imaging) scan will be performed on normal children and young adult volunteers. These studies will be conducted in the MRI systems located in the NIH Clinical Center in Bethesda, Maryland. The results will be used to establish the normal standard MRI measurements for the pediatric population; including left ventricular mass, ejection fractions and other standard cardiac measurements.

Questions about this trial

What is this clinical trial studying?

An observational study of Healthy, run by National Heart, Lung, and Blood Institute (NHLBI) at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 9 Dec 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00353899, which also lists 3 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Dec 2019; AzTrials last refreshed its copy on 8 Nov 2026.
