Computed Tomography

Computed Tomography allows superior evaluation of bony structures (m – photo) and is preferred over conventional radiography especially considering the 3D reconstruction capabilities. Additionally, CT can be used to diagnose intracranial haemorrhage, alterations in ventricular size or shape, midline shift of the falx cerebri, and brain oedema (Platt and others, 2002). CT does not provide good soft tissue detail of the brain parenchyma, but is frequently the preferred modality for evaluation of human head trauma patients for surgical intervention because of the speed of image acquisition. Typically, haemorrhage is hyperattenuating (hyperdense) on a CT in the acute stages. Over time, the density decreases with clot resorption creating a hypoattenuating lesion similar to brain oedema. A CT can provide images for surgical planning, but should only be pursued in patients who are severely affected or deteriorating requiring surgical intervention.

Magnetic Resonance Imaging

Magnetic Resonance Imaging allows superior soft tissue detail and is preferred for evaluation of the brain, especially the caudal cranial fossa which does not image well with CT due to the presence of CT artifacts in this area (Mechtler and others, 2014). MRI can detect more subtle parenchymal changes that may be missed on a CT and may provide information about prognosis. Haematomas or haemorrhage, parenchymal contusions, and oedema are readily apparent on MRI images (m – photo). Although CT is preferred [...]
