What is a CT scan?
A CT scan stands for a Computed Tomography scan. It is an imaging method in radiology. It uses X-rays and a computer to produce images of your internal organs such as bones, tissues, etc. A CT scan offers more clarity and detailed images than a regular X-ray. It is a non-invasive procedure, meaning it is done without any surgical interventions in your body.
A CT scan is a fast, painless, and precise procedure. Its best feature is its ability to simultaneously evaluate and take images of bones, internal organs, and blood vessels. During emergencies, the scan may help identify internal injuries and bleeding. It is a cost-effective method, making it more accessible.

What is a CT scan with contrast?
A CT scan with contrast involves ingesting a special dye called contrast material, which blocks X-rays. This may appear white or opaque in pictures. It helps highlight specific areas of the body like blood vessels, intestines, etc.
