OBJECTIVE To audit the appropriateness of skill radiography in children attending an accident and emergency (A&E) department with head injuries. METHODS 569 children presenting to a large teaching hospital A&E unit were retrospectively audited. The indications for radiography according to British published guidelines and American published guidelines were compared with the actual requests for...

Two female patients presented with multiple radiolucent lesions noted on panoramic radiography. Cone-beam computed tomography (CBCT) scans confirmed “punched-out” affecting the skull.

Radiography is used for initial diagnosis and postoperative follow-up. If a radiograph deemed unsuitable diagnosis, it rejected. Retaking disadvantageous the patient because prolongs examination time increases radiation dose. Skull radiography position in which retaking occurs most frequently. In skull radiography, patient’s rotational direction estimated from minute changes inner ear’s structu...

To demonstrate the phylogenetic changes that have led to the current form of the human skull, dried skulls of various representative vertebrates were examined using plain radiography and high-resolution computed tomography. The latter was chosen rather than pluridirectional tomography in anticipation of its future role as the major method for imaging the skull base. The phylogenetic history of ...

background and aims. panoramic radiography is a method widely used because of low absorbed dose in patients (approximately 10 times less than that in the full mouth survey), reasonable cost and time. disadvantages of this radiography technique are magnification and distortion as a result of unequal magnification, which can influence dimensional and angular measurements used in clinical dentistr...

A two-year-old Thoroughbred colt was presented to the Equine Clinic, Onderstepoort Veterinary Academic Hospital for head trauma after rearing and falling backwards, hitting his head on the ground. Following medical therapy for acute onset neurological impairment secondary to a suspected basilar skull fracture, the horse was anaesthetised and computed tomography of the skull was performed. A dia...

BACKGROUND AND PURPOSE The developing fetal skull base has previously been studied via dissection and low-resolution CT. Most of the central skull base develops from endochondral ossification through an intermediary chondrocranium. We traced the development of the normal fetal skull base by using plain radiography, MR imaging, and CT. METHODS Twenty-nine formalin-fixed fetal specimens ranging...
