The two imaging technologies complement one another perfectly: magnetic reso-
nance imaging (MRI) provides millimeter-precise images of the body’s organs, while
positron emission tomography (PET) displays, above all, the metabolic activity of cells.
The Siemens Biograph mMR is the world’s first device to combine MRI and PET imag-
ing in an integrated system – enabling clinicians to simultaneously capture data on
organ function and metabolism as well as any changes in organs in a single scan.
For patients, this means
diagnoses in less time and with less radiation exposure.
Instead of having to perform several separate scans, clinicians can now acquire all
images in a single process – thus shortening patient waiting times. The integration
of MRI and PET technologies also reduces the amount of radiation that patients are
exposed to, compared to conventional imaging technologies.
Until now, two separate devices were required for these examinations because
the operation of conventional PET detectors is impaired by the strong magnetic fields
gene rated by MRI scanners. Previously, the images generated had to be superimposed
using special software. This second step reduced precision since patients – and thus
organ positions – often shifted between scans. The Siemens Biograph mMR features
new PET detectors whose operation is not disturbed by the MRI’s strong magnetic field.
That’s why the innovative system can capture all data simultaneously, recording even
the smallest details and functional processes. Healthcare facilities also profit from
the Siemens Biograph mMR: the system streamlines processes and cuts costs for floor
space and operation by eliminating the need for a second system. And that’s to the
advantage of a growing number of patients around the world.

A pioneering achievement in medical imaging,
the Biograph mMR combines two previously separate
technologies in a single system.
1 MR scanning has not been established as safe for imaging fetuses and infants less than two years of age. The responsible physician
must evaluate the benefits of the MR examination compared to those of other imaging procedures.
The statements by Siemens’ customers described herein are based on results that were achieved in the customer’s unique setting.
Since there is no “typical” hospital and many variables exist there can be no guarantee that other customers will achieve the same results.
