NCT00001194

Brief Summary

This protocol is designed to investigate the use of novel techniques in MRI that may not yet be commercially available. Specifically, the protocol enables patients to take advantage of new pulse sequence software, coil design or post processing capabilities not otherwise available. The informed consent explains MRI in lay terms, describes the use of contrast agents and lists contraindications to MRI.
