MRCAT Brain

MR-RT clinical application

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.

Features

Unleash the real power of MR simulation

MRCAT Brain lets you plan radiation therapy for patients with primary and metastatic tumors in the brain using MRI as a single-modality solution. Within just one fast MR scan, MRCAT Brain provides excellent soft-tissue contrast for target and OAR delineation, and CT-like density information for dose calculations - directly on the console. This not only extends the benefits of MRI’s outstanding soft-tissue contrast to radiotherapy planning, but it also eliminates arduous, error-prone CT-MRI registration from the process, reducing uncertainties and complexity.

The single scan advantage

With Philips MRCAT (MR for Calculating ATtenuation) Brain imaging protocol, a single mDIXON T1W scan provides information for both contouring and dose calculation for treatment planning. As anatomical and density information originate from the same scan, no image registration is required and spatial and temporal consistency are ensured.

Short scan time promotes patient comfort and productivity

An MR exam can cause stress for patients. Especially if they are immobilized and in treatment position. The MRCAT source scan is accelerated by Compresses SENSE and takes just a few minutes to complete. This promotes patient comfort by minimizing time in the scanner. Furthermore, it can boost productivity by allowing for additional sequences within the timeslot.
