IB Delta T1 Maps
Comparison of standardized (calibrated) pre- (T1) and post-contrast (T1+C) anatomic images.

Overview
Reader misinterpretation and disagreement can contribute to radiologist burnout and diagnostic errors. Standard T1+C imaging can be variable and confounded by other bright enhancing signals, such as post-surgical blood product and may miss subtle enhancing regions which may not appear as an area of concern until weeks or months later in the treatment plan.
Delta T1 Maps aims to resolve this by detecting subtle regions of enhancing while subtracting out blood product and other artifacts that may appear bright on pre-contrast images.




Features
-
The IB Delta T1 module performs post-processing of DICOM images and simplifies post processing tasks.
-
It includes automated image registration features requiring minimal user interaction.
- It performs Voxel Intensity Calibration™ (“standardization”) of MR images.
- It allows for the creation of difference images to ease identification of changes between two images (e.g., signal changes due to contrast uptake between pre- and post-contrast images).
Benefits
- Delta T1 maps aims to make the delineation of contrast enhancing regions more objective, faster and consistent.
- Delta T1 aims to predict early progression comparable with the standard 2d manual method but offers the potential for substantial time and cost savings for clinical trials.
