What is it indicated for?

The Vantage 2.0 ExSPECT option to the ADAC Gamma Camera Systems produces images which depict the anatomical density of a patient. The system is intended to provide an enhancement to the emission images acquired using the ADAC Gamma Camera Systems by correcting for attenuation effects in the patient.

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
