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.

What is a non-contrast CT scan?
There are two types of contrast used in CT, oral and IV. The oral contrast is usually a thin barium sulfate suspension and is used to distend and coat the stomach and intestines. IV contrast is usually a nonionic iodinated liquid injected into your arm. This highlights anatomy with blood flow. A noncontrast ct scan usually refers to NOT using the IV contrast, oral may still be used.
Where does the doctor inject contrast into the abdomen for a Ct of the abdomen and pelvis?
C-T, or computed tomography, is a series of x-rays done in 3 dimensional 'slices' of the study area of the body, which allows for very specific detail of the imaged area. A C-T may be either non-contrast, contrast, or both. No matter what part of the body is being imaged, the liquid contrast material is injected intravenously. A nurse or specially trained technician will start an IV, usually in the arm, and inject the contrast material, and then the C-T scan is performed. If both non-contrast and contrast studies are being performed, the non-contrast study is done first.
What can you eat before a pet scan?

What is an X ray procedure that reveals cross-sectional views of internal structural damage or problems in the brain?
There are two procedures that are non invasive to check for internal and structural problems of the brain. The x-ray procedure that involves cross-sectional views of these internal brain structures is a CAT scan.

How is MRI contrast administered for a brain MRI?
MRI, or Magnetic Resonance Imaging, is an imaging technique using a very powerful magnet and sophisticated detectors or 'scanners' to obtain very detailed images of any part of the body. There is no radiation or x-rays involved. The MRI can be non-contrast, contrast, or both. If both, the non-contrast proceedure is done first. No matter what part of the body is being imaged, the contrast is injected intravenously. A nurse or specially trained technician will start an IV, usually in the arm, and then the liquid contrast material is injected, and the MRI performed.
What is non destructive scanning?
You change the material as part of the scan.
What 2 non destructive methods for improving contrast to an image?
In Photoshop U can use Curves from Adjustments palette or Brightness/Contrast and in Camera Raw all adjustments are non-destructive.
Is brain cancer communicable or non communicable?
