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
Unleash the real power of MR simulation
MRCAT Head and Neck lets you plan radiation therapy using MRI only, without the need for CT. Within just one fast MR exam, MRCAT Head and Neck provides excellent soft-tissue contrast for target and OAR delineation, and CT-like density information for dose calculations. This not only extends the benefits of MRI’s excellent soft-tissue contrast to radiotherapy planning and adaptive strategies, but it also eliminates arduous, error-prone CT-MRI registration from the process.
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.
Short scan times promote patient comfort
Head and neck cancer patients often find it difficult to endure an MRI exam, especially when immobilized by a thermoplastic mask. The high-resolution 3D MRCAT source scan is accelerated by Compressed SENSE and requires < 3 minutes to complete – while covering a large FOV (up to 380 mm in the feet-head direction). This promotes patient comfort, as well as productivity by minimizing time in the scanner.

Recommended products
- The Philips Ingenia MR-RT XD platform harnesses the power and value of MRI for radiation therapy planning. It has been designed around the needs of radiation oncology, with ease-of-use, streamlined integration, and versatility in mind. Central to that concept is the ability to define a tailored approach with customizable functionality that meets your individual clinical, workflow, and budgetary requirements – all to provide better patient care.
- MRCAT Brain clinical application allows the use of MRI as the primary imaging modality for radiotherapy planning of primary and metastatic tumors in the brain without the need for CT. Detailed anatomical information for contouring and attenuation maps for dose calculations are both obtained from a single, submillimeter resolution 3D T1W mDIXON MR sequence. Artificial Intelligence (AI) is used for fast computation of continuous Hounsfield units directly on the MR console.
- As a plug-in clinical application to Ingenia MR-RT, MRCAT Prostate + Auto-Contouring provides attenuation maps and automated, MR-based contours of prostate and organs at risk in as little as 20 minutes – all in a repeatable ‘one-click’ workflow.
- MRCAT Pelvis lets you plan radiation therapy using MRI as a single modality solution. Within just one MR exam, MRCAT Pelvis provides excellent soft-tissue contrast for target and OAR delineation, and continuous Hounsfield units for dose calculations. MRCAT (MR for Calculating ATtenuation) data can be used for export to treatment planning systems for CT-equivalent** dose calculations. In addition, MR-based imaging enables CBCT-based positioning based on soft-tissue contrast with the look and feel of CT.
