Six cadaveric fingers were examined at 11.7T to
determine the appearances of the annular and cruciate
pulleys of the flexor tendons. All named pulleys were
seen. The pulleys showed different anatomic features
including internal structure and magic angle effects
depending on their orientation to Bo. These could
increase or decrease contrast with the surrounding
connective tissue. The study provides a basis for
understanding the visualization of pulleys with clinical
systems at higher field strengths.
