Siemens introduces new hybrid imaging product line at Society of Nuclear Medicine Conference 2004

Philadelphia 21 June 2004Siemens Medical Solutions has unveiled a new concept in hybrid imaging technology at the 51st annual meeting of the Society of Nuclear Medicine (SNM), held June 19-23, 2004 in Philadelphia, Pennsylvania. The new TruePoint Single-Photon Emission Computed Tomography-Computed Tomography (SPECT-CT) technology is the first to combine the functional sensitivity of SPECT with the rich, anatomical detail of diagnostic multi-slice CT, providing clinicians with true imaging clarity and diagnostic confidence.


"Nuclear medicine is a unique imaging modality in that it is used for diagnosis, dosimetry, and therapeutic delivery of effective radiopharmaceuticals. The addition of diagnostic CT will improve all aspects of SPECT imaging, and minimize the scientific guestimates we've relied upon previously", stated Dr. Homer A. Macapinlac, deputy chairman, Department of Nuclear Medicine, MD Anderson Cancer Center in Houston, Texas. "In fact, nuclear medicine has been nicknamed unclear medicine in the past. Having the ability to fuse and register SPECT images with the anatomical images of diagnostic CT scans will instead make it the clear medicine for the future."

TruePoint SPECT-CT uniquely integrates Siemens' state-of-the-art SPECT imaging technology with Siemens' comprehensive, industry-leading CT technology. Also at SNM, Siemens introduced the first platform to incorporate TruePoint SPECT-CT, the Siemens Symbia product family. "The introduction of TruePoint SPECT-CT technology and the Symbia family again demonstrates the commitment Siemens has made to developing leading-edge technology that is responsive to the needs of our clinical partners", stated Michael Reitermann, president of the Siemens Medical Solutions Nuclear Medicine Group. "TruePoint SPECT-CT delivers on the current and future promise of nuclear medicine by maximizing molecular information in combination with precise anatomical detail. This new technology will enable our customers to further pinpoint the exact location, size, nature and extent of disease, anywhere in the body."

TruePoint SPECT-CT has the potential to revolutionize diagnosis and treatment for cancer, cardiac and neurological diseases. With a single scan, this imaging technology quickly captures comprehensive, accurate diagnostic information both on the molecular and anatomical levels, and will enable physicians to detect changes in molecular activity even before structural changes become visible.

In cardiac applications, TruePoint SPECT-CT will provide invaluable information about cardiac function and overall health. TruePoint is the only SPECT-CT technology available to measure attenuation correction with diagnostic multi-slice CT, providing the most accurate attenuation map possible. With earlier and more accurate diagnosis, physicians will be able to plan treatment more effectively and provide feedback on treatment efficacy, as well as avoid unnecessary invasive surgery and reduce the risks of necessary surgery. Ultimately, this is expected to improve the overall care and prognosis for the patient.

"The introduction of new technology like TruePoint SPECT-CT offers the opportunity to re-examine how the diagnostic process works, the order in which studies are performed and the order in which the whole care pathway is constructed", stated Dr. Macapinlac. "It may well be that a hybrid imaging device that's capable of high quality scans in both modalities - SPECT and CT - will offer all the diagnostic and therapeutic advantages you might expect, as well as getting closer to one-stop shopping for the patient, who only has to make one appointment and undergo a seamless procedure."

With the capability to perform multiple scans in a single, automated procedure, TruePoint SPECT-CT provides unrivalled clinical work flow and efficiency. Acquiring multiple studies during one patient visit enhances therapy planning, speeds exam time, and increases comfort and convenience for the patient.

The Symbia platform with TruePoint SPECT-CT technology will enable clinicians to utilize the device in three ways to perform three separate studies - SPECT, multi-slice CT and SPECT-CT - all with a single system. Symbia's small footprint will make it possible to integrate the system into a variety of clinical settings. In addition, the flexible, scalable system architecture allows Siemens to offer a variety of models within the Symbia family, ranging from systems that offer attenuation correction to premium, multi-slice CT capabilities. Symbia offers various multi-slice CT configurations with speeds of up to 0,6 seconds per rotation, allowing acquisition of a high quality CT scan in a few seconds. This will enable physicians to obtain a functionally accurate, anatomically precise SPECT-CT study 20 times faster than other systems on the market.

The integration of syngo, Siemens' unique software platform, into the Symbia operating system also offers a common, intuitive user interface and enables easy access to patient data. syngo, with its multimodality implementation, is uniquely suited for hybrid imaging systems like Symbia. The syngo software also enables fully automated and integrated user interaction counting tools, so that SPECT and CT datasets can be acquired and processed on one single workstation.
