MAGNETOM RT Pro edition for MAGNETOM Aera and SkyraThe time is now for MR in RT.

Customizing a “standard diagnostic” MRI to the needs of RT professionals requires a good amount of effort. In order to provide high process efficiency from the beginning, the MAGNETOM RT Pro edition offers dedicated hardware for the needs of radiation oncologists and enables MR imaging in the treatment position. All RT positioning equipment is tailored to our 70 cm Open Bore scanners to enable smooth workflows and easy patient preparation – for optimal accuracy in radiation therapy.

The MAGNETOM RT Pro edition brings MRI’s excellent soft-tissue contrast to radiation therapy. Our solution comprises dedicated software and applications that advance your capabilities in treatment planning. Benefit from workflow guidance with the RT Dot Engine, helping to ensure consistent results. All protocols included are optimized to improve spatial integrity. Fast isotropic 3D sequences and distortion correction deliver high spatial integrity in regions where it’s most critical to have precise information.

The practical integration of acquired MR data into existing RT workflows is often compromised by limited capabilities of RT planning software solutions to visualize non-axial image data. This missing link is closed with the syngo.via RT Image Suite – a dedicated imaging-for-RT software solution enabling multi-modality image viewing, registration and target contouring. Additional syngo.via software packages support tumor quantification and treatment response assessment to enable optimization of therapy to meet individual needs and thus to improve patient outcome.

Whether for brain lesions or intracranial metastases, MRI helps to provide vital clues for treatment planning of IMRT and Stereotactic Radiosurgery. Siemens provides dedicated RT protocols for Brain as well as Head & Neck exams with the RT Dot Engine. These protocols are optimized for imaging in treatment position with the flexible Tim 4G coils.

In radiation therapy of the prostate, the volume of the organ is often overestimated when using CT only.⁴ With its excellent soft-tissue contrast, MRI can enable a more precise delineation of the prostate and organs at risk. With multi-parametric MRI (diffusion-weighted imaging and Spectroscopy) you can even see metabolically active regions of a tumor which helps to identify regions for dose escalation and enable tailored treatment planning to drive better therapeutic outcomes.⁵

With RESOLVE, diffusion-weighted imaging can be performed with significantly better lesion conspicuity and image quality⁶ and typical distortions are reduced by a factor of three.⁷ Therefore, it is the DWI sequence of choice for accurate target delineation.⁸

For cervical cancers treated with brachytherapy, the EMBRACE study has shown that the ability of MRI to visualize and delineate soft tissue improves target coverage and normal tissue sparing.⁹ With fast isotropic 3D sequences – like SPACE or VIBE – along with 3D distortion correction, you can acquire excellent planning data for the therapy process. Various contrasts for reliable 3D planning in brachytherapy, e.g. T1, T2, and PD are available.
