Ultrasound now spans through an extremely wide range of regular uses, covering needs of the entire spectrum of our citizens. The articles published in this issue of the journal are a very illustrative example of such versatility.

Its use spans from the very early times, like the prenatal intrauterine conditions, moving to the perinatal period, the adult life, times at which CT or MRI are scantly of any use and finally to the disease of the elderly, such as Alzheimer’s dementia.
