A brain scan can be called many things, depending on the specific imaging technique used. Several types of brain scans provide detailed images of the brain's structure and function.
Types of Brain Scans:
-
Magnetic Resonance Imaging (MRI): An MRI uses magnets and radio waves to create detailed images of the brain's structures. A brain MRI, also known as a head MRI, is a painless procedure that produces very clear images. Source: Cleveland Clinic This is a common and widely used method. A specialized type, functional MRI (fMRI), studies brain activity. Source: Mayo Clinic

Computed Tomography (CT or CAT) Scan: A CT scan uses X-rays to create cross-sectional images of the brain. Source: Johns Hopkins Medicine It's often used for quickly identifying brain injuries or bleeding. Source: NIH

Positron Emission Tomography (PET) Scan: A PET scan uses a radioactive tracer to show brain activity and metabolic function.

In summary, the term "brain scan" is a general term; the specific name depends on the imaging modality used, such as MRI, CT, or PET. Each technique offers unique insights into the brain's anatomy and function. Source: Dignity Health
