What is TRAC?
TRAC stands for Tumor Response Assessment by Criteria, which describes a service of reviewing medical imaging modalities with identification and measurements of characterization tumor burden/response. The TRAC reports provided are simultaneously morphologic annotations and calculations of tumor response
The Lesion Overview Chart illustrates how individual target lesions have responded in a stacked chart. This can help delineate graphically the relative response between all target lesions identified.
TRAC reports provide detailed measurements for each target, non-target, and other findings as needed per response criteria. Additionally, the series and slice measured is included for ease of finding lesions in PACS or other.
Lesion Snapshots provide a glimpse into the actual portion of the radiology image which was measured, and shows the outline of the measurement along with the details of the measurement below the image.
How to Order TRAC Reports
While Ordering CT/MR/PET
1. In the ordering interface, at the questions “What type of special image processing is requested, select “Tumor Response Assessment”.
2. Indicate whether this patient is known to participate in a research trial.
3. REQUIRED: Select response criteria. Choose only what is required for care or documented research.
4. Indicate whether the CT/MRI is a baseline or follow-up time point for response. REQUIRED: If follow-up, provide baseline date (when current treatment began.
5. Provide contact info so that we may ask questions when necessary.
After PCT/MR/PET Complete
Enter one of the following orders and also answer the special image processing questions for Tumor Response Assessment.
- CT 3D Tumor Response Evaluation
- MR 3D Tumor Response Evaluation
- PET 3D Tumor Response Evaluation
