Brain skull

?Method of imaging
?Normal appearance
?Abnormal appearance

Methods of imaging
?Plain films .
?Computed tomography .CT scan
?Magnetic resonance imaging .MRI .
?Ultrasound .US
?Angiography
?Radionuclide s

Plain film

There are four standerd projection for skull:
1-Lateral view
2-Posterioanterior view
3-Towens view
4-Basal view

Appearance
?Skull is very complex structure composed of more than 20 different bones .

Fracture of skull
Linear #: appears as lucent lineand should be differentiated from vascular markining.
Depressed #: appears as area of increase density due to fragment overlap

Computed tomography and magnetic resonance imaging


CT scan and MRI are now the imaging technique of choice
