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