HCPCS 70553

Magnetic resonance (eg, proton) imaging, brain (including brain stem); without contrast material, followed by contrast material(s) and further sequences

AI EXPLANATION: A brain MRI is an imaging test that uses strong magnetic fields and radio waves to generate detailed, cross-sectional pictures of the brain and brain stem. In this specific examination, the technologist first takes a series of scans without any dye, then administers an intravenous contrast material through a vein and captures additional sequences. The contrast helps highlight blood vessels, tissue details, and areas of inflammation or abnormal growth.
