Refinement and Assessment of New MRI Technologies for Thoracic/ Cardiovascular Exams

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.

Inclusion Criteria:

- If you are a male or a non-pregnant female patient, age 18 years or older, of any
ethnic background presenting to MRI for a clinically-ordered chest MRI exam, you are
eligible to participate in this study.

- If you are a female of child bearing potential you will be questioned for the
possibility of pregnancy. Pregnancy screening, if necessary, is performed routinely by
ordering physicians prior to MRI scanning to confirm the patient is not pregnant.

Exclusion Criteria:

- Patients who have electrically, magnetically or mechanically activated implants such
as heart pacemaker, magnetic surgical clips, prostheses or implanted neurological
stimulator.

- Pregnant patients or patients who are nursing

- Patients who are claustrophobic.
