Overview

GE’s Perfusion 4D Neuro is a fast,

easy-to-use automated software for analyzing CT Perfusion images related to stroke and tumor angiogenesis. Its simple user interface and fully automated perfusion post-processing make it easy for you to diagnose quickly and accurately – and make treatment decisions more confidently. GE leverages its de-convolution expertise, with its innovative delay corrected algorithm. Perfusion 4D takes perfusion assessment to the next level, with a new Smart Map that creates noise-reduced functional maps while preserving

Perfusion 4D is fast and simple to use, providing automatic tissue assessment of perfusion changes. The protocol-driven design leads the user step-by-step through the process, reducing keystrokes and improving repeatability. So you can get the information you want; quickly and reliably.

• Fully integrated CT brain stroke

protocol that performs the following algorithmic steps:

‐ Image registration ‐ Bone removal

Indications for Use

CT perfusion 4D is an image analysis software package that allows the user to produce dynamic image data and to generate information with regard to changes in image intensity over time. It supports the analysis of CT Perfusion images, obtained by cine imaging (in the head and body) after the intravenous injection of contrast, in calculation of the various perfusion-related parameters (i.e. regional blood flow, regional blood volume, mean transit time and capillary permeability). The results are displayed in a userfriendly graphic format as parametric images. This software will aid in the

assessment of the extent and type of

perfusion, blood volume and capillary permeability changes, which may be related to stroke or tumor

angiogenesis and the treatment

thereof.
