We will recruit patients to participate in the assessment of new MRI technologies designed to improve chest MRI exams that will result in improvements in patient care.~Several different MRI technologies will be evaluated. Specific evaluation of distinct technologies (eg. new head coil design, and new imaging sequence for the spine) may be evaluated simultaneously, or over non-overlapping periods in time.
The purpose of the study is to improve chest MRI exams, eventually resulting in improvements in patient care.
