About this trial

This is an interventional treatment trial for Heart Disease focused on measuring pediatrics, Heart Disease, Cystic Fibrosis, Severe Asthma, Magnetic Resonance Imaging

Eligibility Criteria

6 Years - undefined (Child, Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

Cardiac Patients:

  1. Patients > 6 years of age
  2. Patients with suspected or confirmed congenital or acquired heart disease
  3. Who undergo a clinically indicated MRI scan, including gadolinium (MRI contrast medium)
  4. And receive gadolinium (= MRI contrast medium) as part of their clinical investigation

Pulmonary Patients:

  1. Patients > 6 years of age
  2. Patients with a chronic and stable lung condition, such as cystic fibrosis, severe asthma.

Exclusion Criteria:

  1. Children under the age of 6 will be excluded as they are routinely scanned under general anesthesia
  2. Patients in whom MRI is contraindicated (e.g. pacemaker, ocular metal, claustrophobia, tattoos)
  3. Patients with a known allergy to gadolinium.
  4. Patients with a history of allergic disposition or have anaphylactic reactions
  5. Moderate-to-severe renal impairment (defined as having a GFR/ eGFR < 60 mL/min)
  6. Have Sickle Cell anemia
  7. Known pregnancy, or breast feeding
  8. Patient is uncooperative during a MRI without sedation or anesthesia

Arm Description

In addition to the routine clinical MRI, we will conduct the DCE MR perfusion imaging research component. For this, we will measure native pre-contrast T1 and then inject a tight bolus of gadolinium (0.1mmol/kg) while acquiring high temporal resolution T1-weighted 3D contrast dynamics information over the whole thorax while the patient is holding his / her breath. Overall, the research component will prolong the clinical study by approximately 5 minutes.

Patients in this group will receive a full cardiac and pulmonary MRI assessment, with the DCE pulmonary perfusion scan added as described above. Overall, the investigation will take approximately 45 minutes

Outcomes

Primary Outcome Measures

Pulmonary blood flow
Pulmonary blood flow as measured with DCE MRI perfusion imaging will be compared to MRI phase contrast imaging, which is the gold standard of non-invasive flow measurements.

Secondary Outcome Measures

Perfusion defects detected
Perfusion defects (number and location) will be compared to images of lung morphology and correlated with pathology within the lung parenchyma and central airways.
Quantitative results from dynamic contrast-enhanced magnetic resonance perfusion imaging
Quantitative results from DCE MRI perfusion imaging (including mean transit time, pulmonary blood flow, pulmonary blood volume) will be correlated with the results of pulmonary perfusion tests, where clinically available.

5. Study Description

Brief Summary
The primary objective of this study is to determine if quantitative Dynamic contrast-enhanced magnetic resonance (DCE MR) perfusion imaging accurately quantifies right and left pulmonary artery blood flow as compared with phase contrast flow velocity mapping (PC), the current gold standard of flow volume measurements.
Detailed Description
Many conditions of the heart or the lungs lead to differences in how the blood is pumped to the lungs. Specifically, some areas of the lung may receive less blood supply than others. We would like to do a research study in children and adolescents who have a heart condition or a chronic or stable lung condition. We are doing this study to see if measuring the circulation of blood in the lungs in children is possible using magnetic resonance imaging (MRI) with a special dye (contrast medium) injection called Magnevist®.

Intervention Type
Procedure
Intervention Name(s)
Phase contrast flow velocity mapping (PC)
Intervention Description
An MRI is done using the phase contrast flow velocity mapping (PC)technique. Using PC, an imaging slice is prescribed perpendicular to the vessel's course. Within the pulmonary circulation, PC can quantify total pulmonary blood flow and the right / left distribution of the lung blood flow volume.
Intervention Type
Procedure
Intervention Name(s)
Dynamic contrast-enhanced magnetic resonance imaging
Intervention Description
Dynamic contrast-enhanced magnetic resonance (DCE MR) perfusion imaging imaging is a non-invasive method to quantify regional pulmonary blood flow. A bolus of gadolinium-containing contrast medium is injected and its passage through the pulmonary circulation traced using a repetitive rapid three-dimensional (3D) T1 weighted angiography sequence.
