💬In plain words
What the trial is, and whether it could suit you
Background:
\- Magnetic resonance imaging (MRI) scans must be performed according to specified sets of parameters that provide optimal images of each organ and each area of the body. These scanning parameters are often specific to the institution or organization at which they are employed, and may also depend on the manufacturer of the MRI scanning equipment. Because MRI scanning equipment is always being updated and upgraded, researchers are interested in developing new and optimized scanning parameters for MRI scans.
Objectives:
\- To improve current methods and develop new techniques for magnetic resonance imaging.
Eligibility:
* Individuals 18 years of age and older who are either volunteers or current NIH protocol participants.
* Participants must not have any medical history factors (e.g., extreme claustrophobia, history of metal implants) that would prevent them from receivin

📋 Eligibility rules (as published)
* INCLUSION CRITERIA:
A. Volunteer individuals
B. Lab Eligibility parameters (for contrast scans within 4 weeks of gadolinium injection):
C. Creatinine below upper normal limit
D. eGFR \>= 60 mL/min/1.73m2
E. Age \>= 60 or history of renal disease: test GFR within 1 week prior to contrast
F. Willing to travel to the NIH for follow-up visits.
G. 18 years old
H. Able to understand and sign informed consent
I. No MRI scan with gadolinium injection in the last 6 months under this protocol.
EXCLUSION CRITERIA:
A. Implanted metal clips or wires of the type which may concentrate radiofrequency fields or cause tissue damages from twisting in a Magnetic field. Examples:
* Aneurysm clip, implanted neural stimulator,
* Implanted cardiac pacemaker, defibrillator, or certain other implanted electrical or metallic devices,
* Cochlear implant, ocular foreign body (metal shavings),
* Any implanted device (pumps, infusion devices, etc.),
* Shrapnel injuries,
* History of metal in head or eyes or other parts of the body.
B. Pregnant women
C. Paralyzed hemidiaphragm
D. Over 500 lbs and/or a body circumference that prevents the study subject from laying flat in the scanner
E. Surgery of uncertain type
F. Untreatable claustrophobia otherwise requiring anesthesia.
G. Any contraindications that the Physician identifies from the subject, MRI Safety Questionnaire, and/or History and Physical.
EXCLUSION FOR PARTICIPANTS FOR GADOLINIUM CONTRAST:
(Inclusive of the above exclusion criteria):
A. Allergy to gadolinium for scans using contrast; will be eligible for non-contrast scans.
B. Acute renal failure, renal transplant, dialysis and renal failure individuals (eGFR \<60 mL/min/1.73m2 and/or clinically diagnosed).
C. Individuals with a history of liver transplant or severe liver disease.
D. Lactating women
E. Individuals with hemoglobinopathies or severe asthma.
F. Patient preference to not undergo intravenous line placement and/or receive gadolinium contrast. Contrast administration is optional and participants may still undergo a non-contrast study.
G. GBCA with an MRI scan in the last 6 months. This includes scan performed with GBCA at any outside institution and / or at the clinical center .In addition, they cannot have reached their maximum of 4 GBCA imaging studies under this protocol. They will be excluded from having a contrast enhanced MRI, but will not be excluded from the protocol for non-contrast MRI studies.
