Special Considerations
MRI is superior to computed tomography (CT) in most cases where differentiation of soft tissues is necessary. It can view organs without obstruction by bone and foreign bodies. It is capable of showing the tissues from multiple viewpoints and is a noninvasive way to evaluate blood flow.
A CT scan may be preferred for:
- acute trauma of the head and face
- acute (less than 72 hours) neurologic dysfunction
- early symptoms of stroke
- subarachnoid or intracranial hemorrhage (within the first 24 to 48 hours)
- skull bone disorders, disorders involving the bones of the ear
