5 Indications for a CT Scan of the Head Without Contrast

There are five main categories that a CT scan of the head without contrast can view well. They are listed below:

1. Hemorrhage
2. Sinuses
3. Midline shift
4. Bones
5. Ventricles/Empty space

Of course these structures are visualized on other imaging modalities, but a CT without contrast is able to see them particularly well. A good list to keep in mind when choosing an imaging modality! Plus, it keeps the kidneys happy.
