Why isn't cranial US an option in children older than a few months? O The soft spot is too small. O The increased ultrasound power necessary at that age is potentially brain-damaging. O The brain has become too thick for ultrasonic waves to adequately penetrate. O None of these are the reason
Ultrasound imaging is based on the same principles involved in the sonar used by bats, ships, and submarines. When a sound wave strikes an object, it bounces back, or echoes. By measuring the echo waves , it is possible to determine how far the object is, as well as the object’s size, shape and consistency (solid or fluid).
In medicine, ultrasound is to detect changes in the appearance of organs, tissues, and vessels and to detect abnormal masses, such as tumors.
Ultrasound imaging of the head uses sound waves to generate pictures of the brain and the cerebrospinal fluid.
Head ultrasound is a routine exam for infants who were born prematurely. The procedure is used to screen for brain conditions associated with prematurity, such as bleeding or brain tissue damage.
