Ask Dr. Z

This was performed by the radiologist in the hospital setting. Can the radiologist bill anything for the CT perfusion study? "Craniocaudad Z axis spiral acquisition performed during injection of Omnipaque. Automated arterial and venous inputs used to create maps of cerebral blood volume, flow, transit times, and Tmax parameters. Findings: Normal CT perfusion with no findings of ischemia or infarction. Contrast was then instilled and patient sent to CT scanner. Impression: Good distribution of contrast with normal appearance of imaged osseous structures. Uncomplicated fluoro-guided lumbar puncture for instillation of myelographic contrast."
