CT (Computed Tomography) scanning uses X-rays and computer processing to create detailed cross-sectional images of the body. It's faster than MRI, widely available, and excellent for bone, lung, and vascular imaging. Contrast agents (iodinated) can be injected to highlight blood vessels and lesions. Key uses include trauma, stroke, cancer staging, and pulmonary embolism detection.

Now let me search the medical library for detailed textbook content on CT scans.

I found key textbook sections. Let me read the dedicated CT sections from Grainger & Allison's (the radiology textbook) and Cummings Otolaryngology, and also get the CT image from the Frameworks book.

Excellent textbook content retrieved. Let me also get a CT image to include in the response.
