What is non contrast cat scan?

A non-contrast CT scan is a type of computed tomography imaging that does not use any contrast agents, such as iodine-based dyes, to enhance the visibility of internal structures. It helps in diagnosing various conditions, including fractures, tumors, and internal bleeding, by providing detailed cross-sectional images of the body. This method is often preferred in situations where patients may have Allergies to contrast materials or when rapid imaging is needed. Non-contrast CT scans are commonly used for evaluating the head, abdomen, and chest.
