IB Delta T1 Maps
Performs post-processing of MR T1-weighted images and simplifies post-processing tasks.

- T1
- contrast enhancement
- regions of interest
- ROI
Output includes an anatomic image showing the areas of true contrast enhancement.

IB Delta T1 may provide greater sensitivity for stratifying subpopulations over adjudicated 2D manual delineation of enhancing tumor reads.1

Can predict early progression comparable with standard 2D manual method but has the potential for substantial time and cost savings for clinical trials.1

What Customers Are Saying
The T1 with contrast is hard to interpret, but I think the Delta T1 says it all.

What Customers Are Saying
When new areas of enhancement are identified, our surgeons and neuro-oncologists want to see IB's Delta T1 maps and standardized rCBV on our patients to guide therpeutic and surgical management. The additional information added by IB's maps to conventional imaging is instrumental in patient management.
