Put the advantages of the MAGNETOM World to work for you!
MAGNETOM systems are indicated for use as magnetic resonance diagnostic devices (MRDD) that produce transverse, sagittal, coronal and oblique cross sectional images, spectroscopic images and/or spectra, and that display the internal structure and/or function of the head, body or extremities. These images and/or spectra and the physical parameters derived from the images and/or spectra when interpreted by a trained physician, yield information that may assist in diagnosis.. The study protocols, application tips, lectures and presentations contained in this document were developed entirely by the medical professionals identified in the respective articles. These medical professionals did not receive financial support or any other kind of assistance from Siemens Healthineers.
Patient results may vary depending on many factors including system, software version, options, coils, technique and patient condition. Siemens Healthineers is not responsible or liable for results.
Protocols
Radiation Oncology is experiencing growth in the use of magnetic resonance imaging in treatment planning and response assessment. While it can seem daunting to start integrating this technology in Radiation Therapy departments, this trend is inevitable and has been embraced by physicists and physicians alike. Clinical teams of several institutions have created their own solutions to optimize images, in an effort to add valuable clinical insights in treatment planning. This booklet is a compilation of study protocols* and practical tips for several body regions provided by these experts.
This compilation is being shared to foster clinical knowledge among medical professionals.
We would like to thank all the contributors who have worked tirelessly and generously shared their knowledge and expertise.
We look forward to hearing your feedback and suggestions so that we at Siemens Healthineers can continuously improve and do our part in the care of our patients.
