MRCAT Head and Neck
MR-RT clinical application
MRCAT Head and Neck enables the use of MRI as a primary imaging modality for radiotherapy planning of patients with soft tissue tumors in the Head and Neck, without the need for CT. Powered by AI, MRCAT (MR for Calculating ATtenuation) images with CT-like density information are automatically generated from a single, high-resolution MR scan and can be used for CT-equivalent¹ dose calculations and accurate² patient positioning.

Features
Consistent, accurate imaging protocol
Image acquisition is made easy by a dedicated ExamCard that includes a single, multi-contrast 3D T1W mDIXON scan, which is standardized to deliver consistent results and high geometric accuracy. The MRCAT Head and Neck scan can be acquired before or after contrast agent administration. Additional sequences, e.g. for delineation, can be easily added to the protocol to address your specific clinical needs.
Automatic generation of synthetic CT images using AI
MRCAT Head and Neck uses Artificial Intelligence (AI) for fast computation of MRCAT attenuation maps based on the mDIXON source scan. The resulting MRCAT density maps provide continuous Hounsfield Units for CT-like image appearance and are shown right at the MR console for immediate review.
Rely on MRCAT-based patient positioning
You can use MRCAT data for patient positioning verification at the linac that is as accurate² as with conventional CT images. MRCAT’s continuous Hounsfield units, with the look and feel of CT, enable CBCT-based positioning using soft-tissue or bony contrast. You can also use MRCAT data to generate MR-based digitally reconstructed radiographs (DRRs) to allow for patient positioning using bony structures.
