Occupational exposure levels of static magnetic field during routine MRI examination in 3T MR system.

abstract：:Several investigators have reported robust, statistically significant results that indicate that weak (approximately 1 microT) magnetic fields (MFs) increase the rate of morphological abnormalities in chick embryos. However, other investigators have reported that weak MFs do not appear to affect embryo morphology at a...
