The effect of magnetic resonance imaging on neural tube development in an early chicken embryo model.

Purpose: We aimed to determine whether varying the magnetic field during magnetic resonance imaging would affect the development of chicken embryos and neural tube defects.

Methods: Following incubation for 24 h, we exposed chicken embryos to varying magnetic fields for 10 min to assess the impact on development. Three magnetic resonance imaging devices were used, and the eggs were divided into four groups: group 1 is exposed to 1 T, group 2 is exposed to 1.

Olfactory functions after transsphenoidal pituitary surgery: endoscopic versus microscopic approach.

Objectives/hypothesis: Olfactory disturbances could be observed following transsphenoidal pituitary surgeries. To our knowledge, no previous comparative studies on olfactory functions after transsphenoidal endoscopic and microscopic approaches have been performed.

Study Design: Prospective study comparing olfactory functions between endoscopic and microscopic transsphenoidal pituitary surgery.
