[NMR tomographic measurement of femoral ante-torsion and tibial torsion].
OBJECTIVE
A new MRI method for the measurement of femoral torsion and tibial torsion is presented.


METHODS
Axial images were generated using a standard gradient echo sequence (FLASH 2D). Otherwise measurement of femoral and tibial torsion was performed according to an established CT method.


RESULTS
The torsion angles measured using MRI were in accordance with the angles measured using the CT method. The MRI method was not more time-consuming than the CT method.


CONCLUSIONS
In respect of radiation exposure, MRI determination of femoral and tibial torsion should be considered particularly in children and patients who have to undergo repeated torsion measurements.
