Offering nuclear cardiology solutions

Nuclear cardiologists who use Siemens’ Symbia Intevo™ xSPECT¹ system—the latest evolution in SPECT and CT integration—can dramatically reduce the length of imaging protocols with IQ●SPECT, a field-upgradeable hardware and software combination that enables the reduction of imaging time from 16 minutes to 4 minutes, or up to 75% less injected dose.2 These shortened exams allow a sustainable approach to nuclear cardiology that enables improved acquisition time and reduced patient dose without compromising high-quality diagnostic information.


Siemens’ Biograph mCT Flow™¹ positron emission tomography/computed tomography (PET●CT) system helps assess coronary artery disease (CAD) and heart damage as well as differentiate healthy muscle from damaged muscle.¹ Biograph mCT Flow provides automated, rigid registration of CT and PET during cardiac imaging. A proprietary algorithm identifies the heart and aligns the two images for optimal attenuation correction, improving workflow and reducing user variability. The system allows the user to verify PET/CT registration accuracy in either patient (transverse/sagittal/coronal) or cardiac (SA/VLA/HLA) orientation. Biograph mCT Flow helps the user automatically detect respiratory motion during cardiac studies, enabling dual-gated PET with cardiac-gated list mode acquisition for optimal motion-frozen imaging, offline histogramming, and reconstruction.

Optimizing cardiac workflow with Dot

Siemens developed the Cardiac Dot® (Day optimizing throughput) Engine to reduce the complexity of cardiac magnetic resonance imaging (MRI) and to increase productivity by guiding the user through cardiac exams. With a few mouse clicks, the Cardiac Dot Engine automatically selects customized protocols based on the patient’s clinical condition. Through user guidance, patient personalization, and exam automation provided by Cardiac Dot workflow technology, users can increase productivity in the healthcare setting as much as 50 percent.³

Providing quantitative cardiac assays

A comprehensive portfolio of assays such as cTnI, BNP, NT-proBNP, and CardioPhase® hsCRP helps manage patients throughout the continuum of cardiovascular disease. Siemens offers troponin testing on several of its core testing platforms, including ADVIA Centaur® systems, Dimension Vista® systems, and Dimension® EXL™ systems, and provides consistent results by offering true clinical concordance between the point of care and central laboratory for guideline-compliant sensitive cardiac troponin. The Stratus® CS Acute Care™ Diagnostics System provides quantitative cardiac assays for fast, accurate evaluation of patients presenting with acute myocardial infarction (AMI) at the point of care. These assays include the Stratus® CS Acute Care™ Troponin I method (cTnl), 4 which, by helping to improve the diagnostic accuracy and rapid detection of AMI, facilitates earlier detection of myocardial injury, enabling more rapid diagnosis and faster initiation of appropriate therapy.
