Characteristic MR Findings of Growing Skull Fracture in Children
complication of skull fracture, occurring almost exclusively in infants and children under the age of three (1, 2). It follows head trauma with accompanying skull fracture. Dural tear associated with skull fracture is the basic mechanism by which this condition occurs. Growing skull fracture is most commonly observed in the frontal and parietal regions, but it can occur anywhere in the skull (3...
متن کاملSequential changes of traumatic vertebral compression fracture on MR imaging.
The purpose of this study was to evaluate the sequential signal intensity changes in post-traumatic vertebral compression fractures of varying ages. Sixty-six patients with 115 post-traumatic vertebral compression fractures underwent MR imaging. The ages of fractures at the time of MR images ranged from 1 day to 6 years. Sequential follow-up MR imagings were obtained in 4 patients for 2 years a...
متن کاملStudying friction and shear fracture in thin confined films using a rotational shear apparatus.
This paper describes the effects of the elastic modulus and sliding velocity on the friction and shear fracture of smooth silanized rigid disks rotating against thin confined films of poly(dimethylsiloxane) (PDMS) elastomers. A rigid glass disk is rotated against thin PDMS films of different thicknesses and moduli bonded to a glass plate at various speeds. While the disk rotates on the PDMS coa...
متن کاملGolgi's apparatus
Golgi reported an " internal reticular apparatus " in neurons — a structure now known as the Golgi apparatus. Although this is by far his best-remembered work, Golgi made many other important scientific discoveries in his lifetime (1843–1926), and in 1906 shared the Nobel prize for Physiology or Medicine with Santiago Ramón y Cajal for their studies on the structure of the nervous system. As we...
