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. Advanced applications and imaging sequences, such as RESOLVE and MR spectroscopy, provide additional pathology characterization. And with fast isotropic 3D sequences – like SPACE or VIBE – along with 3D distortion correction, you can achieve better anatomical correlation. Apply dose to the target, spare the organs at risk.

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 and 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.1 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.2

With RESOLVE, diffusion-weighted imaging can be performed with significantly better lesion conspicuity and image quality3 and typical distortions are reduced by a factor of three.4 Therefore, RESOLVE is strongly suited for accurate target delineation.


The EMBRACE study has shown for cervical cancers treated with brachytherapy, that the ability of MRI to visualize and delineate soft tissue improves target coverage and normal tissue sparing:5 MRI used in brachytherapy of cervix carcinoma significantly improves target coverage and reduced organ-at-risk dose.
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.
