MR-only Radiotherapy Planning
Powered by syngo.via RT Image Suite
While MR provides excellent soft-tissue contrast and functional information, CT is still required for electron density information for accurate dose calculation. As a result, many institutions have to adapt their RT treatment planning workflow, in which patients are normally scanned on both imaging modalities. Fusing CT and MRI modalities makes the workflow more complicated and adds uncertainties in the planning process.1, 2
MR-based Synthetic CT offers the possibility of combining the superior soft-tissue contrast of MRI for organs-at-risk and target delineation with dosimetric planning. An MR-only workflow eliminates the need for CT to MRI registration, reducing systematic registration errors and unnecessary ionizing radiation from CT scans.

Compressed Sensing GRASP-VIBE for other regions than liver is not for sale in the U.S. Intended Use: Compressed Sensing GRASP-VIBE (GRASP = Golden-angle Radial Sparse Parallel MRI) is intended to be used in dynamic and/or non-contrast liver examinations to support patients who cannot reliably hold their breath for a conventional breath-hold measurement.
