Yes, a CAT scan is indeed a CT scan.
CAT (Computed Axial Tomography) scan is an older term for what is now commonly referred to as a CT (Computed Tomography) scan. Both terms refer to the same medical imaging technique that uses X-rays to create detailed cross-sectional images of the body. The "axial" part of the older term, CAT scan, has been dropped as CT scans can now acquire data in a variety of ways other than strictly axial.
Therefore, when someone refers to a CAT scan, they are essentially talking about the same procedure as a CT scan. The change in terminology reflects advancements in the technology and capabilities of the imaging technique.
