          The objective of this study was to use short and 
						ultrashort TE pulse sequences to demonstrate and 
						distinguish between the collagenous components of 
						peripheral nerve (external epineurium, internal 
						epineurium and perineurium) at 3T and 11.7T. These 
						tissues are not usually demonstrable with standard pulse 
						sequences. Conventional spin echo, 2D and 3D UTE, and 
						UTE-IR sequences were used. Magic angle effects and 
						susceptibility effects were observed. We were able to 
						specifically identify the epineurium and the perineurium 
						within peripheral nerve. Assessing the integrity of 
						these structures is critical for grading peripheral 
						nerve injuries and determining the need for 
						neurosurgical repair.
