SOMATOM Definition Edge“Exceeding expectations“ VS. “Accepting the average“ – Second best is not an option.

Confronted with increasingly complex clinical requirements and rising numbers of patients, medical institutions are expected to perform at the limits of capacity every day. The new SOMATOM Definition Edge helps you not only meet, but exceed these expectations by improving your institution’s process efficiency and patient outcome in all clinical capabilities – from contrast media-efficient TAVI planning to precise therapy response management, from low dose therapy control to optimized emergency care workflow.

  • Exceeding expectations in:
  • Cardiology
  • Emergency Medicine
  • Oncology

A follow-up scan of a liver metastasis after microwave ablation treatment acquired by TwinBeam Dual Energy2 shows a hypodense lesion in the liver and in the right kidney. The image contrast is greatly increased by monoenergetic imaging. And both lesions show no significant enhancement in the fused VNC/ iodine image. Therefore, residual tumor tissue can be confidently excluded and a kidney cyst can be diagnosed.
