Technical Performance Assessment of Quantitative Imaging in Radiological Device Premarket Submissions: Guidance for Industry and Food and Drug Administration Staff

FinalCenter for Devices and Radiological Health06/16/2022

Description

This guidance document provides FDA's recommendations on the information, technical performance assessment, and user information that should be included in a premarket submission for radiological devices that include quantitative imaging functions. The recommendations reflect current review practices and are intended to promote consistency and facilitate efficient review of premarket submissions for radiological devices that include quantitative imaging functions.
