Refinement and Assessment of New MRI Technologies for Thoracic/ Cardiovascular Exams
The purpose of the study is to improve MRI examinations of the chest region that will result in an improvement in patient care.

- New MRI Technologies [ Time Frame: 3 years ] [ Designated as safety issue: No ]
Assessment of the new technologies will be quantified by a variety of performance and image quality/content measures. The appropriate set of measures will be selected based on specific features offered by each assessed technology, but will be drawn from the following quantities:
- Scan speed: Scan speed is time required to set-up and run the new technique relative to the standard method.
- Signal to noise: SNR (signal to noise ratio)is the ratio of average image intensity in target tissue relative to standard deviation of background areas (outside of body). This is a fundamental parameter used to quantify relative performance of new imaging sequences/hardware/software.
- Contrast to noise: CNR (contrast to noise)is the difference in average image intensity between two target tissues relative to noise. This is a key descriptor to quantity lesion/tissue conspicuity, thus is used to characterize relative performance of new imaging sequence/hardware/software.
