The women's vaginal closure force at rest and while contracting her pelvic muscle also was measured. Women with prolapse were found to have a much higher rate of major ...Vaginal birth increases risk of hemorrhage in newborns
...BROOK, Ill. The first researchers to use magnetic resonance imaging (MRI) to study the brains of a large group of babies soon after birth found a small amount of bleeding in and around the brains of one in four babies who were delivered vaginally. The study appears in the February issue of Radiology. "Smal...MR angiography highly accurate in detecting blocked arteries

The scans revealed that a region of the brain called the posterior superior temporal sulcus was activated to a greater degree ...Novel computed imaging technique uses blurry images to enhance view
..., ISAM can do for optical microscopy what magnetic resonance imaging did for nuclear magnetic resonance, and what computed tomography did for X-ray imaging, the scientists say.
