Physical, morphological and biochemical effects of prenatal ultrasound exposure on rabbit fetus / Farah Wahida Ahmad Zaiki

Ultrasound is extensively used in various clinical specialties throughout the developed world since it was perceived to lack in bioeffects. Somehow, through the advances in the capability of ultrasound equipment that triggered greater image processing power, the revision of potential bioeffects is n...
