The overall purpose is to study how a variety of technological approaches in Magnetic resonance imaging (MRI) can be used to provide improved performance non-contrast MR imaging as used for angiography and perfusion.  These include but are not limited to improvements in: (i) receiver coils; (ii) pulse sequences for data acquisition; (iii) methods for image reconstruction; (iv) algorithms for deriving MRI-based quantitative parameters and biomarkers.

The purpose of this study is to evaluate whether newly developed acquisition techniques or 1.5 Tesla and 3.0 Tesla MRI scanners systems can provide improvements over current acquisition techniques. The objective of this protocol is to allow investigators to perform initial test evaluation in humans of new MRI acquisition techniques.  

All pulse sequences, including the ones that we testing, can be used on FDA-approved MRI scanners as long as they meet FDA guidelines for non-significant risk, and our new sequences all meet these guidelines.

All MRI test scans of new pulse sequences will be performed subject to FDA guidelines which have been determined to pose Non-Significant Risk.

The purpose of this study is to look at a contrast-enhanced MR angiography method in comparison to current methods. The contrast-enhanced method can generate images with more spatial detail and can be used to view a much larger region of the patient’s body than is presently possible.
