Traumatic lesions to the brain are well seen without i.v. contrast agents. In particular, traumatic hemorrhage, be it epidural, subdural, subarachnoid, parenchymal or intraventricular, is spontaneously hyperdense on CT. Theoretically, i.v. contrast would be, at best useless, at worst counterproductive.
A non contrast brain CT scan can pick up bleeds in or around the brain. It can also detect skull fractures and calcifications within the brain. Certain tumours can also be seen without the use of contrast.
Yes, brain tumours can show up very clearly on CT scans especially if the patient is injected with an X-ray dye.
There are no generally contraindicated medications after a contrast enhanced Ct Scan.
A brain scan after a head trauma is nearly always done without contrast, because bleeding also shows up white on the scan. The scan should be done as quickly as possible with the shortest scan time because patients with head injuries are often restless. If there is a suspected neck injury, the patients head will have be scanned in the position it is in, and the patient can not be moved into the 'head box'. After the scan, both brain and bone setting views should be looked at to establish if there are any fractures.

"Unremarkable" in a CT of the brain without contrast means that there are no abnormal findings or any significant issues detected in the brain images. It suggests that the brain appears normal and there are no visible signs of disease or injury.
CT Head or Brain w/o contrast
Yes, brain tumours can show up very clearly on CT scans especially if the patient is injected with an X-ray dye.
CT scans with contrast, and CT scans without contrast.
There are no generally contraindicated medications after a contrast enhanced Ct Scan.
A CT Scan can image an aneurysm without a contrast injection even though it does better with a contrast agent. An MRI will require an contrast agent or an MRI/MRA.
