MAGNETOM RT Pro edition

MRI delivers excellent soft-tissue contrast as well as exact information on tumor extent and functional parameters, therefore it can add substantial value to radiotherapy. Between 2006 and 2013 its utilization in radiotherapy planning has increased from 6% to 21%.1

The MAGNETOM RT Pro edition for MAGNETOM Aera and Skyra is a comprehensive hardware and software package that helps advance your institution’s clinical capabilities by efficiently integrating this additional modality into existing processes.

Equipped with dedicated positioning support devices and protocols for RT, the MAGNETOM RT Pro edition supports radiation therapy with precision and efficiency. Benefit from MRI information along the complete RT process with multi-modality image viewing. Tailored hardware and software help you increase your institution’s capabilities and advance patient outcome.

Siemens - MRI - MAGNETOM RT Pro edition - Image - A sound basis for MR in RT

Easily scan patients in the treatment position

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.

Partnerships for exact positioning throughout the therapy process:

Consistently rely on intuitive workflows and spatial integrity

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.

Effectively establish multi-modality image viewing and precise contouring2

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.

Approche clinique

MRI offers excellent soft-tissue contrast without dose, making it ideal for RT purposes where computed tomography (CT) information can be enriched with valuable MR information. Check out the examples below to see how the MAGNETOM RT Pro edition helps you expand your clinical capabilities in radiation therapy.

Siemens - MRI in Therapy - MAGNETOM RT Pro edition - Image - Head and Head & Neck

Brain and Head & Neck

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.

Prostate

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

Siemens - MRI - Clinical Application - RESOLVE - Image

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

Gynecological

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.

Caractéristiques techniques

MAGNETOM Aera and MAGNETOM Skyra are MR systems that can meet the needs of high-precision radiation therapy. Excellent image quality and speed are possible with its Tim 4G technology combined with leading applications. Their 70 cm Open Bore can fit a variety of immobilization devices.

3The MRI restrictions (if any) of the metal implant must be considered prior to patient undergoing MRI exam. MR imaging of patients with metallic implants brings specific risks. However, certain implants are approved by the governing regulatory bodies to be MR conditionally safe. For such implants, the previously mentioned warning may not be applicable. Please contact the implant manufacturer for the specific conditional information. The conditions for MR safety are the responsibility of the implant manufacturer, not of Siemens.
