Potential heating effect in the gravid uterus during MR HASTE imaging.
Our purpose was to evaluate if temperature changes occur in maternal or fetal tissues during HASTE imaging.


METHODS
Pregnant pigs were scanned with the HASTE technique, and temperatures were measured with phase maps and temperature probes inserted into the amniotic fluid and fetal brain.


RESULTS
Fiberoptic probes showed that no heating occurred in fetal tissues or amniotic fluid during HASTE imaging.


CONCLUSIONS
Our current HASTE protocols do not deposit a significant amount of heat in the gravid uterus. J. Magn. Reson. Imaging 2001;13:856-861.
