First, look at the machine. You want a modern digital scanner, not some legacy machine taking forever while exposing you to way more radiation than necessary. Newer tech captures sharper data in a fraction of the time. Next, check the actual credentials. Accreditations like NABH follow strict safety, hygiene, and calibration protocols day in and day out, and the team running the equipment matters just as much as the steel itself. You need certified nuclear medicine techs operating the bed and seasoned specialists reading the scans, not some automated software churning out generic reports in the background.
